############################################################################
# OVERVIEW
############################################################################
# This file contains possible settings you can use to configure inputs,
# distributed inputs such as forwarders, and file system monitoring in
# inputs.conf.
#
# Each stanza controls different search commands settings.
#
# There is an inputs.conf file in the $SPLUNK_HOME/etc/system/default/ directory.
# Never change or copy the configuration files in the default directory.
# The files in the default directory must remain intact and in their original
# location.
#
# To set custom configurations, create a new file with the name inputs.conf in
# the $SPLUNK_HOME/etc/system/local/ directory. Then add the specific settings
# that you want to customize to the local configuration file.
# For examples, see inputs.conf.example.
#
# You must restart the Splunk platform instance to enable configuration changes.
#
# To learn more about configuration files (including file precedence) see the
# documentation located at
# http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles
#

############################################################################
# GLOBAL SETTINGS
############################################################################
# Use the [default] stanza to define any global settings.
#   * You can also define global settings outside of any stanza, at the top of
#     the file.
#   * Each .conf file should have at most one default stanza. If there are
#     multiple default stanzas, settings are combined. In the case of
#     multiple definitions of the same setting, the last definition in the
#     file wins.
#   * If a setting is defined at both the global level and in a specific
#     stanza, the value in the specific stanza takes precedence.
#   * Do not add any new global settings to the [default] stanza unless you 
#     understand all the repercussions of your changes. It is especially 
#     important not to add new settings if your inputs.conf file is created 
#     in an app that has global permissions or is located in the 
#     $SPLUNK_HOME/etc/system directory. 
#   * Modifying the inputs.conf file might cause other apps or splunkd to fail.

############################################################################
# GENERAL SETTINGS:
# The following settings are valid for all input types (except file system
# change monitor, which is described in a separate section in this file).
# You must first enter a stanza header in square brackets, specifying the input
# type. See later in this file for examples. Then, use any of the
# following settings.
#
# To specify global settings for Windows Event Log inputs, place them in
# the [WinEventLog] global stanza as well as the [default] stanza.
############################################################################

host = <string>
* Sets the host key/field to a static value for this input stanza.
* The input uses this field during parsing and indexing. It also uses this
  field at search time.
* As a convenience, the input prepends the chosen string with 'host::'.
* When set to '$decideOnStartup', sets the field to the hostname of executing
  machine. The hostname is checked and the field set at every splunkd startup.
* If you run multiple instances of the software on the same machine (hardware
  or virtual machine), choose unique values for 'host' to differentiate
  your data, ex. myhost-sh-1 or myhost-idx-2.
* Do not put the <string> value in quotes. Use host=foo, not host="foo".
* When 'host' is set to "$decideOnStartup", you can further control how splunkd
  derives the hostname by using the 'hostnameOption' setting in server.conf.
  * For example, if you want splunkd to use the fully qualified domain
    name for the machine, set "host = $decideOnStartup" in inputs.conf and
    "hostnameOption = fullyqualifiedname" in server.conf.
  * More information on hostname options can be found in the server.conf
    specification file.
* If you remove the 'host' setting from $SPLUNK_HOME/etc/system/local/inputs.conf
  or remove $SPLUNK_HOME/etc/system/local/inputs.conf, the setting reverts to
  "$decideOnStartup". Apps that need a resolved host value should use the
  'host_resolved' property in the response for the REST 'GET' call of the
  input source. This property is set to the hostname of the local Splunk
  instance. It is a read only  property that is not written to inputs.conf.
* Default: "$decideOnStartup"

run_only_one= <boolean>
* Determines if a scripted or modular inputs runs on one search head
  in SHC.
* Currently not supported. This setting is related to a feature that is
  still under development.
* Default: true

index = <string>
* Sets the index to store events from this input.
* Primarily used to specify the index to store events that come in through
  this input stanza.
* Default: main (or whatever you have set as your default index)

source = <string>
* Sets the source key/field for events from this input.
* Detail: Sets the source key initial value. The key is used during
  parsing/indexing, in particular to set the source field during
  indexing. It is also the source field used at search time.
* As a convenience, the chosen string is prepended with 'source::'.
* Avoid overriding the source key. The input layer provides a more accurate
  string to aid in problem analysis and investigation, recording the file
  from which the data was retrieved. Consider using source types, tagging,
  and search wildcards before overriding this value.
* Do not put the <string> value in quotes: Use source=foo,
  not source="foo".
* Default: the input file path

sourcetype = <string>
* Sets the sourcetype key/field for events from this input.
* Explicitly declares the source type for this input instead of letting
  it be determined through automated methods. This is important for
  search and for applying the relevant configuration for this data type
  during parsing and indexing.
* Sets the sourcetype key initial value. The key is used during
  parsing or indexing to set the source type field during
  indexing. It is also the source type field used at search time.
* As a convenience, the chosen string is prepended with 'sourcetype::'.
* Do not put the <string> value in quotes: Use sourcetype=foo,
  not sourcetype="foo".
* If not set, the indexer analyzes the data and chooses a source type.
* No default.

queue = [parsingQueue|indexQueue]
* Sets the queue where the input processor deposits the events it reads.
* Set to "parsingQueue" to apply the props.conf file and other parsing rules to
  your data. For more information about the props.conf file and rules
  timestamps and linebreaks, see the props.conf file and the
  online documentation at http://docs.splunk.com/Documentation.
* Set to "indexQueue" to send your data directly into the index.
* Default: parsingQueue

# Pipeline Key defaulting.

* Pipeline keys in general can be defaulted in inputs stanzas.
* The list of user-available, modifiable pipeline keys is described in
  transforms.conf.spec. See transforms.conf.spec for further information on
  these keys.
* The currently-defined keys which are available literally in inputs stanzas
  are as follows:

queue = <value>
_raw = <value>
_meta = <value>
_time = <value>

* Inputs have special support for mapping host, source, sourcetype, and index
  to their metadata names such as host -> Metadata:Host
* Defaulting these values is not recommended, and is
  generally only useful as a workaround to other product issues.
* Defaulting these keys in most cases overrides the default behavior of
  input processors, but this behavior is not guaranteed in all cases.
* Values defaulted here, as with all values provided by inputs, can be
  altered by transforms at parse time.

############################################################################
# This section contains options for routing data using inputs.conf rather than
# outputs.conf.
#
# NOTE: Concerning routing via inputs.conf:
# This is a simplified set of routing options you can use as data comes in.
# For more flexible options or details on configuring required or optional
# settings, see outputs.conf.spec.
############################################################################

_TCP_ROUTING = <comma-separated list>
* A comma-separated list of tcpout group names.
* This setting lets you selectively forward data to one or more specific indexers.
* Specify the tcpout group that the forwarder uses when forwarding the data.
  The tcpout group names are defined in outputs.conf with
  [tcpout:<tcpout_group_name>].
* To forward data to all tcpout group names that have been defined in
  outputs.conf, set to '*' (asterisk).
* To forward data from the "_internal" index, you must explicitly set
  '_TCP_ROUTING' to either "*" or a specific splunktcp target group.
* Default: The groups specified in 'defaultGroup' in [tcpout] stanza in
  the outputs.conf file

_SYSLOG_ROUTING = <comma-separated list>
* A comma-separated list of syslog group names.
* Use this setting to selectively forward the data to specific destinations as
  syslog events.
* Specify the syslog group to use when forwarding the data.
  The syslog group names are defined in outputs.conf with
  [syslog:<syslog_group_name>].
* The destination host must be configured in outputs.conf, using
  "server=[<ip>|<servername>]:<port>".
* This setting does not work on a universal forwarder.
* Default: The groups specified in 'defaultGroup' in the [syslog] stanza in
  the outputs.conf file

_INDEX_AND_FORWARD_ROUTING = <string>
* If set for any input stanza, causes all data coming from that input
  stanza to be labeled with this setting.
* When 'selectiveIndexing' is in use on a forwarder:
  * Data without this label will not be indexed by that forwarder.
  * Data with this label will be indexed in addition to any forwarding.
* This setting does not actually cause data to be forwarded or not forwarded in
  any way, nor does it control where the data is forwarded in multiple-forward
  path cases.
* Only has effect if you use the 'selectiveIndexing' feature in outputs.conf.
* Default: not set

############################################################################
# Deny list
############################################################################

[blacklist:<path>]
* Protects files on the file system from being indexed or previewed.
* The input treats a file as denied if the file starts with any of the
  defined deny list <paths>.
* Adding a file to the deny list with the specified path occurs even if a monitor
  stanza defines an allow list that matches the file path.
* The preview endpoint returns an error when asked to preview an
  excluded file.
* The oneshot endpoint and command also returns an error.
* When a denied file is monitored, using monitor:// or batch://,
  the 'filestatus' endpoint shows an error.
* For fschange with the 'sendFullEvent' option enabled, contents of
  denied files are not indexed.

############################################################################
# Input types
############################################################################
Valid input stanzas, along with their input-specific settings, follow:

############################################################################
# MONITOR:
############################################################################

[monitor://<path>]
* Configures a file monitor input to watch all files in the <path> you specify.
* <path> can be an entire directory or a single file.
* You must specify the input type and then the path, so put three slashes in
  your path if you are starting at the root on *nix systems (to include the
  slash that indicates an absolute path).

# Additional settings:

host_regex = <regular expression>
* If specified, <regular expression> extracts host from the path to the file
  for each input file.
    * Detail: This feature examines the source key; if source is set
      explicitly in the stanza, that string is matched, not the original
      filename.
* Specifically, the first group of the regular expression (regex) is used
  as the host.
* If the regex fails to match, the input uses the default 'host' setting.
* If 'host_regex' and 'host_segment' are both set, the input ignores 'host_regex'.
* No default.

host_segment = <integer>
* If set to N, the Splunk platform sets the Nth "/"-separated segment of the path
  as 'host'.
    * For example, if you set "host_segment = 3" and the path is
      /logs/servers/host08/abc.txt, the third segment, "host08", is used.
* If the value is not an integer or is less than 1, the default 'host'
  setting is used.
* On Windows machines, the drive letter and colon before the backslash *does not*
  count as one segment.
    * For example, if you set "host_segment = 3" and the monitor path is
      D:\logs\servers\host01, Splunk software sets the host as "host01" because
      that is the third segment.
* No default.

whitelist = <regular expression>
* If set, files from this input are monitored only if their path matches the
  specified regular expression.
* Takes precedence over the deprecated '_whitelist' setting, which functions
  the same way.
* No default.

blacklist = <regular expression>
* If set, files from this input are NOT monitored if their path matches the
  specified regex.
* Takes precedence over the deprecated '_blacklist' setting, which functions
  the same way.
* If a file matches the regexes in both the deny list and allow list settings,
  the file is NOT monitored. Deny lists take precedence over allow lists.
* No default.

NOTE concerning wildcards and monitor:
* You can use wildcards to specify your input path for monitored inputs. Use
  "..." for recursive directory matching and "*" for wildcard matching in a
  single directory segment.
* "..." searches recursively through one or more directories. This means that
  /foo/.../bar matches foo/1/bar, foo/1/2/bar, etc.
* You can use multiple "..." specifications in a single input path. For
  example: /foo/.../bar/...
* The asterisk (*) matches anything in a single path segment; unlike "...", it
  does not search recursively. For example, /foo/*/bar matches the files
  /foo/1/bar, /foo/2/bar, etc. However, it does not match
  /foo/bar or /foo/1/2/bar.
  A second example: /foo/m*r/bar matches /foo/mr/bar, /foo/mir/bar,
  /foo/moor/bar, etc. It does not match /foo/mi/or/bar.
* You can combine "*" and "..." as needed: foo/.../bar/* matches any file in
  the bar directory within the specified path.
* A monitor stanza path will interpret regular expression metacharacters as
  strings unless they are preceded by the wildcard values "*" or "..." in a prior
  segment of the path.
* In the case where multiple unique monitor inputs overlap through the use of
  wildcards or specific paths defined in the monitor stanza, the Splunk platform
  processes the files using the monitor stanza that is the closest
  specific match.

crcSalt = <string>
* Use this setting to force the input to consume files that have matching CRCs,
  or cyclic redundancy checks.
    * By default, the input only performs CRC checks against the first 256
      bytes of a file. This behavior prevents the input from indexing the same
      file twice, even though you might have renamed it, as with rolling log
      files, for example. Because the CRC is based on only the first
      few lines of the file, it is possible for legitimately different files
      to have matching CRCs, particularly if they have identical headers.
* If set, <string> is added to the CRC.
* If set to the literal string "<SOURCE>" (including the angle brackets), the
  full directory path to the source file is added to the CRC. This ensures
  that each file being monitored has a unique CRC. When 'crcSalt' is invoked,
  it is usually set to <SOURCE>.
* Be cautious about using this setting with rolling log files; it could lead
  to the log file being re-indexed after it has rolled.
* In many situations, 'initCrcLength' can be used to achieve the same goals.
* Default: empty string

initCrcLength = <integer>
* How much of a file, in bytes, that the input reads before trying to
  identify whether it has already seen the file.
* You might want to adjust this if you have many files with common
  headers (comment headers, long CSV headers, etc) and recurring filenames.
* Cannot be less than 256 or more than 1048576.
* CAUTION: Improper use of this setting causes data to be re-indexed. You
  might want to consult with Splunk Support before adjusting this value - the
  default is fine for most installations.
* Default: 256 (bytes)

ignoreOlderThan = <non-negative integer>[s|m|h|d]
* The monitor input compares the modification time on files it encounters
  with the current time. If the time elapsed since the modification time
  is greater than the value in this setting, Splunk software puts the file
  on the ignore list.
* Files on the ignore list are not checked again until the Splunk
  platform restarts, or the file monitoring subsystem is reconfigured. This
  is true even if the file becomes newer again at a later time.
  * Reconfigurations occur when changes are made to monitor or batch
    inputs through Splunk Web or the command line.
* Use 'ignoreOlderThan' to increase file monitoring performance when
  monitoring a directory hierarchy that contains many older, unchanging
  files, and when removing or adding a file to the deny list from the
  monitoring location is not a reasonable option.
* Do NOT select a time that files you want to read could reach in
  age, even temporarily. Take potential downtime into consideration!
  * Suggested value: 14d, which means 2 weeks
  * For example, a time window in significant numbers of days or small
    numbers of weeks are probably reasonable choices.
  * If you need a time window in small numbers of days or hours,
    there are other approaches to consider for performant monitoring
    beyond the scope of this setting.
* NOTE: Most modern Windows file access APIs do not update file
  modification time while the file is open and being actively written to.
  Windows delays updating modification time until the file is closed.
  Therefore you might have to choose a larger time window on Windows
  hosts where files may be open for long time periods.
* Value must be: <number><unit>. For example, "7d" indicates one week.
* Valid units are "d" (days), "h" (hours), "m" (minutes), and "s"
  (seconds).
* No default, meaning there is no threshold and no files are
  ignored for modification time reasons

followTail = <boolean>
* Whether or not the input should skip past current data in a monitored file
  for a given input stanza.
* This setting lets you skip over data in files, and immediately begin indexing
  current data.
* If you set to "1", monitoring starts at the end of the file (like
  *nix 'tail -f'). The input does not read any data that exists in
  the file when it is first encountered. The input only reads data that
  arrives after the first encounter time.
* If you set to "0", monitoring starts at the beginning of the file.
* This is an advanced setting. Contact Splunk Support before using it.
* Best practice for using this setting:
  * Enable this setting and start the Splunk instance.
  * Wait enough time for the input to identify the related files.
  * Disable the setting and restart the instance.
* Do not leave 'followTail' enabled in an ongoing fashion.
* Do not use 'followTail' for rolling log files (log files that get renamed as
  they age) or files whose names or paths vary.
* Default: 0

alwaysOpenFile = <boolean>
* Whether or not an input opens a file to check whether it has already
  been indexed, by skipping the modification time and size checks.
* Only useful for files that do not update modification time or size.
* Only known to be needed when monitoring files on Windows, mostly for
  Internet Information Server logs.
* Configuring this setting to "1" can increase load and slow indexing. Use it
  only as a last resort.
* Default: 0

time_before_close = <integer>
* The amount of time, in seconds, that the file monitor must wait for
  modifications before closing a file after reaching an End-of-File
  (EOF) marker.
* Tells the input not to close files that have been updated in the
  past 'time_before_close' seconds.
* Default: 3

multiline_event_extra_waittime = <boolean>
* Whether or not the file monitor input delays sending an event delimiter when
  it reads a file with multiple-line events, to account for the time it
  sometimes takes for lines of those events to arrive.
* By default, the file monitor sends an event delimiter when:
  * It reaches EOF of a file it monitors and
  * The last character it reads is a newline.
* In some cases, it takes time for all lines of a multiple-line event to
  arrive.
* Set to "true" to delay sending an event delimiter until the time that the
  file monitor closes the file, as defined by the 'time_before_close' setting,
  to allow all event lines to arrive.
* Default: false

recursive = <boolean>
* Whether or not the input monitors subdirectories that it finds within a
  monitored directory.
* A value of "true" means the input monitors sub-directories.
* A value of "false" means the input does not monitor sub-directories.
* Default: true

followSymlink = <boolean>
* Whether or not the input follows any symbolic links within a monitored directory.
* A value of "true" means the input follows symbolic links
  and monitors files at the symbolic link destination.
* Additionally, any allow lists or deny lists that the input stanza defines
  also apply to files at the symbolic link destination.
* A value of "false" means the input ignores symbolic links
  that it finds within a monitored directory.
* Default: true

_whitelist = ...
* DEPRECATED.
* This setting is valid unless the 'whitelist' setting also exists.

_blacklist = ...
* DEPRECATED.
* This setting is valid unless the 'blacklist' setting also exists.


############################################################################
# BATCH  ("Upload a file" in Splunk Web):
############################################################################

Use the 'batch' input for large archives of historic data. If you
want to continuously monitor a directory or index small archives, use 'monitor'
(see the MONITOR section). 'batch' reads in the file and indexes it, and then
deletes the file on disk.

[batch://<path>]
* A one-time, destructive input of files in <path>.
* This stanza must include the 'move_policy = sinkhole' setting.
* This input reads and indexes the files, then DELETES THEM IMMEDIATELY.
* For continuous, non-destructive inputs of files, use 'monitor' instead.

# Additional settings:

move_policy = sinkhole
* This setting is required. You *must* include "move_policy = sinkhole"
  when you define batch inputs.
* This setting causes the input to load the file destructively.
* CAUTION: Do not use the 'batch' input type for files you do not want to
  delete after indexing.
* The 'move_policy' setting exists for historical reasons, but remains as a
  safeguard. As an administrator, you must explicitly declare
  that you want the data in the monitored directory (and its sub-directories) to
  be deleted after being read and indexed.

host_regex = see the definition in the MONITOR section.
host_segment = see the definition in the MONITOR section.
crcSalt = see the definition in the MONITOR section.
time_before_close = see the definition in the MONITOR section.

log_on_completion = <boolean>
* Whether or not the Splunk platform writes an entry into the
  splunkd.log file when it indexes files with this input.
* When set to "false", this setting prevents the Splunk platform from
  writing to splunkd.log when it indexes files with this input.
* Default: true

# 'batch' inputs do not use the following setting:
# source = <string>

followSymlink = <boolean>
* Works similarly to the same setting for monitor, but does not delete files
  after following a symbolic link out of the monitored directory.

# The following settings work identically as for [monitor::] stanzas,
# documented previously
host_regex = <regular expression>
host_segment = <integer>
crcSalt = <string>
recursive = <boolean>
whitelist = <regular expression>
blacklist = <regular expression>
initCrcLength = <integer>
time_before_close = <integer>


############################################################################
# TCP: Transport Control Protocol (TCP) network inputs
############################################################################

[tcp://<remote server>:<port>]
* Configures the input to listen on a specific TCP network port.
* If a <remote server> makes a connection to this instance, the input uses this
  stanza to configure itself.
* If you do not specify <remote server>, this stanza matches all connections
  on the specified network port.
* Generates events with source set to "tcp:<port>", for example: tcp:514
* If you do not specify a sourcetype, the input generates events with sourcetype
  set to "tcp-raw".

# Additional settings:

connection_host = [ip|dns|none]
* How the network input sets the host field for the events it generates.
* A value of "ip" sets the host to the IP address of the system sending the data.
* A value of "dns" sets the host to the reverse DNS entry for the IP address of
  the system that sends the data. For this to work correctly, set the forward
  DNS lookup to match the reverse DNS lookup in your DNS configuration.
* A value of "none" leaves the host as specified in inputs.conf, typically the
  hostname of the system running Splunk software.
* Default: dns

queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB

persistentQueueSize = <integer>[KB|MB|GB|TB]
* The maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
  persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
  interact, search the online documentation for "persistent queues".
* If you set this to a value other than 0, then 'persistentQueueSize' must
  be larger than either the in-memory queue size (as defined by the 'queueSize'
  setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
  server.conf).
* Default: 0 (no persistent queue)

requireHeader = <boolean>
* Whether or not to require a header be present at the beginning of every
  stream.
* This header can be used to override indexing settings.
* Default: false

listenOnIPv6 = [no|yes|only]
* Whether or not the input listens on IPv4, IPv6, or both protocols.
* Set to "yes" to listen on both IPv4 and IPv6 protocols.
* Set to "only" to listen on only the IPv6 protocol.
* Default: The setting in the [general] stanza of the server.conf file

acceptFrom = <comma- or space-separated list>
* A list of TCP networks or addresses to accept connections from.
* Use commas or spaces to separate multiple network rules.
* The accepted formats for network and address rules are:
    1. A single IPv4 or IPv6 address (examples: "192.0.2.3", "2001:db8::2:1")
    2. A Classless Inter-Domain Routing (CIDR) block of addresses
       (examples: "192.0.2/24", "2001:DB8::/32")
    3. A DNS name. Use "*" as a wildcard.
       (examples: "myhost.example.com", "*.example.org")
    4. The wildcard "*" matches anything.
* A prefix of '!' for an entry sets a rule to deny and reject connections. The ACL
 applies rules in order, and uses the first matching rule. For example,
 the rules "!192.0.2/24, *" prevents connections from the 192.0.2/24
 network, but accepts all other connections.
* Default: * (accept from anywhere)

rawTcpDoneTimeout = <seconds>
* The amount of time, in seconds, that a network connection can remain idle
  before Splunk software declares that the last event over that connection
  has been received.
* If a connection over this port remains idle for more than
  'rawTcpDoneTimeout' seconds after receiving data, it adds a Done-key. This
  declares that the last event has been completely received.
* Default: 10

[tcp:<port>]
* Configures the input listen on the specified TCP network port.
* This stanza is similar to [tcp://<remote server>:<port>], but listens for
  connections to the specified port from any host.
* Generates events with a source of tcp:<port>.
* If you do not specify a sourcetype, generates events with a source type of
  tcp-raw.
* This stanza supports the following settings:

connection_host = [ip|dns|none]
queueSize = <integer>[KB|MB|GB]
persistentQueueSize = <integer>[KB|MB|GB|TB]
requireHeader = <boolean>
listenOnIPv6 = [no|yes|only]
acceptFrom = <comma- or space-separated list>
rawTcpDoneTimeout = <integer>

############################################################################
# Data distribution:
############################################################################

# Global settings for splunktcp. Used on the receiving side for data forwarded
# from a forwarder.

[splunktcp]
route = [has_key|absent_key:<key>:<queueName>;...]
* Settings for the light forwarder.
* The receiver sets these parameters automatically -- you do not need to set
  them yourself.
* The property route is composed of rules delimited by ';' (semicolon).
* The receiver checks each incoming data payload through the cooked TCP port
  against the route rules.
* If a matching rule is found, the receiver sends the payload to the specified
  <queueName>.
* If no matching rule is found, the receiver sends the payload to the default
  queue specified by any queue= for this stanza. If no queue= key is set in
  the stanza or globally, the receiver sends the events to the parsingQueue.

enableS2SHeartbeat = <boolean>
* Specifies the global keepalive setting for all splunktcp ports.
* This option is used to detect forwarders which might have become unavailable
  due to network, firewall, or other problems.
* The receiver monitors each connection for presence of a heartbeat, and if the
  heartbeat is not seen for 's2sHeartbeatTimeout' seconds, it closes the
  connection.
* Default: true (heartbeat monitoring enabled)

s2sHeartbeatTimeout = <integer>
* The amount of time, in seconds, that a receiver waits for heartbeats from
  forwarders that connect to this instance.
* The receiver closes a forwarder connection if it does not receive
  a heartbeat for 's2sHeartbeatTimeout' seconds.
* Default: 600 (10 minutes)

inputShutdownTimeout = <integer>
* The amount of time, in seconds, that a receiver waits before shutting down
  inbound TCP connections after it receives a signal to shut down.
* Used during shutdown to minimize data loss when forwarders are connected to a
  receiver.
* During shutdown, the TCP input processor waits for 'inputShutdownTimeout'
  seconds and then closes any remaining open connections.
* If all connections close before the end of the timeout period,
  shutdown proceeds immediately, without waiting for the timeout.

stopAcceptorAfterQBlock = <integer>
* The amount of time, in seconds, to wait before closing the splunktcp port.
* If the receiver is unable to insert received data into the configured queue
  for more than the specified number of seconds, it closes the splunktcp port.
* This action prevents forwarders from establishing new connections to this
  receiver.
* Forwarders that have an existing connection will notice the port is closed
  upon test-connections and move to other receivers.
* After the queue unblocks, and the TCP input can continue processing data, the
  receiver starts listening on the port again.
* This setting should not be adjusted lightly as extreme values can interact
  poorly with other defaults.
* NOTE: If there are multiple tcp/splunktcp listener ports configured,
  all listening ports will be shut down regardless of whether other queues are
  blocked or not.
* Default: 300 (5 minutes)

listenOnIPv6 = no|yes|only
* See the description for this setting in the [tcp://<remote server>:<port>]
  stanza.

acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]
  stanza.

negotiateProtocolLevel = <unsigned integer>
* If set, lets forwarders that connect to this receiver (or specific port)
  send data using only up to the specified feature level of the Splunk
  forwarder protocol.
* If set to a value that is lower than the default, denies the use
  of newer forwarder protocol features during connection negotiation. This
  might impact indexer efficiency.
* Default (if 'negotiateNewProtocol' is "true"): 1
* Default (if 'negotiateNewProtocol' is not "true"): 0

negotiateNewProtocol = <boolean>
* DEPRECATED.
* Use the 'negotiateProtocolLevel' setting instead.
* Controls the default configuration of the 'negotiateProtocolLevel' setting.
* Default: true

concurrentChannelLimit = <unsigned integer>
* The number of unique channel codes that are available for forwarders to
  use to communicate with an indexer.
* Each forwarder that connects to this indexer may use up to
  'concurrentChannelLimit' unique channel codes.
* In other words, each forwarder may have up to 'concurrentChannelLimit'
  channels in flight concurrently.
* The receiver closes a forwarder connection if a forwarder attempts to
  exceed this value.
* This setting only applies when the new forwarder protocol is in use.
* Default: 300

logRetireOldS2S = <boolean>
* Whether or not the Splunk platform logs the usage of old versions of Splunk-to-Splunk (S2S) 
  protocol.
* The old S2S protocol retirement logs provide visibility into customers' usage 
  of the old S2S protocol version V3 which is less performant than the current version V4.
* A value of "true" means that splunkd generates warning logs for the old S2S protocol 
  versions.  
* See the 'logRetireOldS2SRepeatFrequency' setting for additional constraints on
  when the Splunk platform logs the use of old S2S protocol versions. 
* Default: true


logRetireOldS2SMaxCache = <unsigned integer>
* The size of the cache for tracking forwarders that use old S2S protocols.
* The cache keeps track of unique forwarders that use the old S2S protocol. When a 
  forwarder is in the cache, the Splunk platform doesn't log usage of the old protocol
  for that forwarder for a time period of 'logRetireOldS2SRepeatFrequency', to avoid generating 
  duplicate logs.
* If the cache fills before the 'logRetireOldS2SRepeatFrequency' period elapses, 
  the Splunk platform removes the forwarder that has been in the cache the longest
  from the cache to make space.
* Update this setting as per the number of forwarders that currently use the old S2S 
  protocol to send data to indexers. If the number of forwarders that use 
  old S2S protocols is larger than the cache size, some forwarders might generate duplicate 
  logs even though the previous log was within the 'logRetireOldS2SRepeatFrequency' 
  period.
* When you restart Splunk Enterprise, the cache resets and the timer starts over.
* This setting takes effect only when 'logRetireOldS2S' has a value of "true".
* Default: 10000

logRetireOldS2SRepeatFrequency = <timespan>
* The interval between writing repeat entries into the retire old S2S warning log 
  for a certain forwarder.
* This setting helps reduce retire old S2S log size by providing control over how
  often to log.
* When a forwarder uses the old S2S protocol version to communicate with splunkd, splunkd 
  adds the forwarder to a cache. Subsequent communication with the same 
  forwarder won't generate a new entry to the log until a period of 
  'logRetireOldS2SRepeatFrequency' has elapsed. Splunkd then resets the log timestamp and 
  writes another "retire old S2S protocol" warning log entry.
* The Splunk platform enforces this setting as long as the size of the cache
  does not exceed 'logRetireOldS2SMaxCache' entries. When there are more than
  'logRetireOldS2SMaxCache' entries, the cache removes the entry with the oldest
  access time to make space.
* When you restart Splunk Enterprise, the cache resets and the timer starts over.
* This setting takes effect only when 'logRetireOldS2S' has a value of "true".
* A value of "0" means that the platform logs old S2S protocol warning entries every time
  it receives a communication using the old S2S protocol version.
* Default: 1d

# Forwarder-specific settings for splunktcp.

[splunktcp://[<remote server>]:<port>]
* Receivers use this input stanza.
* This is the same as the [tcp://] stanza, except the remote server is assumed
  to be a Splunk instance, most likely a forwarder.
* <remote server> is optional. If you specify it, the receiver listens only for
  data from <remote server>.
  * Use of <remote server> is not recommended. Use the 'acceptFrom' setting,
    which supersedes this setting.

connection_host = [ip|dns|none]
* For splunktcp, the 'host' or 'connection_host' is be used if the remote
  Splunk instance does not set a host, or if the host is set to
  "<host>::<localhost>".
* "ip" sets the host to the IP address of the system sending the data.
* "dns" sets the host to the reverse DNS entry for IP address of the system
  that sends the data. For this to work correctly, set the forward DNS lookup
  to match the reverse DNS lookup in your DNS configuration.
* "none" leaves the host as specified in inputs.conf, typically the Splunk
  system hostname.
* Default: ip

compressed = <boolean>
* Whether or not the receiver communicates with the forwarder in
  compressed format.
* Applies to non-Secure Sockets Layer (SSL) receiving only. There is no
  compression setting required for SSL.
* A value of "true" means the receiver communicates with the forwarder in
  compressed format.
* If set to "true", there is no longer a requirement to also set
  "compressed = true" in the outputs.conf file on the forwarder.
* Default: false

enableS2SHeartbeat = <boolean>
* Specifies the keepalive setting for the splunktcp port.
* This option is used to detect forwarders which might have become unavailable
  due to network, firewall, or other problems.
* The receiver monitors the connection for presence of a heartbeat, and if it
  does not see the heartbeat in 's2sHeartbeatTimeout' seconds, it closes the
  connection.
* This overrides the default value specified at the global [splunktcp] stanza.
* Default: true (heartbeat monitoring enabled)

s2sHeartbeatTimeout = <integer>
* The amount of time, in seconds, that a receiver waits for heartbeats from
  forwarders that connect to this instance.
* The receiver closes the forwarder connection if it does not see a heartbeat
  for 's2sHeartbeatTimeout' seconds.
* This overrides the default value specified at the global [splunktcp] stanza.
* Default: 600 (10 minutes)

queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB

negotiateProtocolLevel = <unsigned integer>
* See the description for this setting in the [splunktcp] stanza.

negotiateNewProtocol = <boolean>
* See the description for this setting in the [splunktcp] stanza.

concurrentChannelLimit = <unsigned integer>
* See the description for this setting in the [splunktcp] stanza.

[splunktcp:<port>]
* This input stanza is the same as [splunktcp://[<remote server>]:<port>], but
  the input accepts connections from any server.
* See the online documentation for [splunktcp://[<remote server>]:<port>] for
  more information on the following supported settings:

connection_host = [ip|dns|none]
compressed = <boolean>
enableS2SHeartbeat = <boolean>
s2sHeartbeatTimeout = <integer>
queueSize = <integer>[KB|MB|GB]
negotiateProtocolLevel = <unsigned integer>
negotiateNewProtocol = <boolean>
concurrentChannelLimit = <unsigned integer>

# Access control settings.
[splunktcptoken://<token name>]
* Use this stanza to specify forwarders from which to accept data.
* You must configure a token on the receiver, then configure the same
  token on forwarders.
* The receiver discards data from forwarders that do not have the
  token configured.
* This setting is enabled for all receiving ports.
* This setting is optional.
* NOTE: When specifying a <token name>, you must use a specific format,
  as follows: NNNNNNNN-NNNN-NNNN-NNNN-NNNNNNNNNNNN. Failure to use this
  format results in the token being ignored.
  * For example, 'A843001F-B2B5-4F94-847D-D07802685BB2'

token = <string>
* The value of the token.
* Must be in the format NNNNNNNN-NNNN-NNNN-NNNN-NNNNNNNNNNNN. Failure to
  use this string format results in the token being ignored.

# SSL settings for data distribution:

[splunktcp-ssl:<port>]
* Use this stanza type if you are receiving encrypted, parsed data from a
  forwarder.
* Set <port> to the port on which the forwarder sends the encrypted data.
* Forwarder settings are set in outputs.conf on the forwarder.
* Compression for SSL is enabled by default. On the forwarder you can still
  specify compression with the 'useClientSSLCompression' setting in
  outputs.conf.
* The 'compressed' setting is used for non-SSL connections. However, if you
  still specify 'compressed' for SSL, ensure that the 'compressed' setting is
  the same as on the forwarder, as splunktcp protocol expects the same
  'compressed' setting from forwarders.

connection_host = [ip|dns|none]
* See the description for this setting in the [splunktcp:<port>] stanza.
* Default: ip

compressed = <boolean>
* See the description for this setting in the [splunktcp:<port>] stanza.

* Select whether this receiver listens on IPv4, IPv6, or both protocols.
* Set to "yes" to listen on both IPv4 and IPv6 protocols.
* Set to "only" to listen on only the IPv6 protocol.
* Default: The setting in the [general] stanza of the server.conf file

acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]

* Use this stanza type if you are receiving encrypted, unparsed data from a
  forwarder or third-party system.
* Set <port> to the port on which the forwarder/third-party system is sending
  unparsed, encrypted data.
* To create multiple SSL inputs, you can add the following attributes to each
  [tcp-ssl:<port>] input stanza. If you do not configure a certificate in the
  port, the certificate information is pulled from the default [SSL] stanza:
  * serverCert = <path_to_cert>
  * sslRootCAPath = <path_to_cert> Only add this setting if you
    have not configured the 'sslRootCAPath' setting in server.conf.
  * sslPassword = <string>

* Select whether the receiver listens on IPv4, IPv6, or both protocols.
* Set to "yes" to listen on both IPv4 and IPv6 protocols.
* Set to "only" to listen on only the IPv6 protocol.
* If not present, the receiver uses the setting in the [general] stanza
  of server.conf.

password = <string>
* DEPRECATED.
* Do not use this setting. Use the 'sslPassword' setting instead.

rootCA = <string>
* DEPRECATED.
* Do not use this setting. Use 'server.conf/[sslConfig]/sslRootCAPath' instead.
* Used only if 'sslRootCAPath' is not set.
* The path must refer to a PEM format file that contains one or more root CA
  certificates that have been concatenated together.

requireClientCert = <boolean>
* Whether or not a client must present an SSL certificate to authenticate.
* A value of "true" means that clients must present a certificate to authenticate.
* Default (if using self-signed and third-party certificates): false
* Default (if using the default certificates; overrides the existing
  "false" setting): true

sslVersions = <comma-separated list>
* A list of SSL versions to support.
* The versions available are "ssl3", "tls1.0", "tls1.1", and "tls1.2"
* The special version "*" selects all supported versions. The version "tls"
  selects all versions that begin with "tls".
* To remove a version from the list, prefix it with "-".
* SSLv2 is always disabled. Specifying "-ssl2" in the version list has
  no effect.
* When configured in Federal Information Processing Standard (FIPS) mode, the
  "ssl3" version is always disabled, regardless of this configuration.
* The default can vary. See the 'sslVersions' setting in
  $SPLUNK_HOME/etc/system/default/inputs.conf for the current default.

supportSSLV3Only = <boolean>
* DEPRECATED.
* SSLv2 is now always disabled.
* Use the 'sslVersions' setting to set the list of supported SSL versions.

cipherSuite = <string>
* If set, uses the specified cipher string for the input processors.
* Must specify 'dhFile' to enable any Diffie-Hellman ciphers.
* The default can vary. See the 'cipherSuite' setting in
  $SPLUNK_HOME/etc/system/default/inputs.conf for the current default.

ecdhCurveName = <string>
* DEPRECATED.
* Use the 'ecdhCurves' setting instead.
* This setting specifies the Elliptic Curve Diffie-Hellman (ECDH) curve to
  use for ECDH key negotiation.
* Splunk software only supports named curves that have been specified
  by their SHORT name.
* The list of valid named curves by their short and long names
  can be obtained by running this CLI command:
  $SPLUNK_HOME/bin/splunk cmd openssl ecparam -list_curves
* Default: empty string

ecdhCurves = <comma-separated list>
* A list of ECDH curves to use for ECDH key negotiation.
* The curves should be specified in the order of preference.
* The client sends these curves as a part of an SSL Client Hello.
* The server supports only the curves specified in the list.
* Splunk software only supports named curves that have been specified
  by their SHORT names.
* The list of valid named curves by their short and long names can be obtained
  by running this CLI command:
  $SPLUNK_HOME/bin/splunk cmd openssl ecparam -list_curves
* Example setting: "ecdhCurves = prime256v1,secp384r1,secp521r1"

allowSslRenegotiation = <boolean>
* Whether or not to let SSL clients renegotiate their connections.
* In the SSL protocol, a client might request renegotiation of the connection
  settings from time to time.
* A value of "false" means the server rejects all renegotiation
  attempts, which breaks the connection.
* This limits the amount of CPU a single TCP connection can use, but it can
  cause connectivity problems, especially for long-lived connections.
* Default: true

sslQuietShutdown = <boolean>
* Enables quiet shutdown mode in SSL.
* Default: false

logCertificateData = <boolean>
* Whether or not the Splunk platform logs certificate data for
  Transport Layer Security (TLS) certificates.
* The certificate data logs provide visibility into the certificates
  in use for the Splunk-to-Splunk (S2S) channel. The logs collect data such
  as common name (CN), issuer name, SHA256 fingerprint, serial number, and
  validity dates.
* A value of "true" means that splunkd generates logs for TLS certificates.
* Refer to the 'certLogRepeatFrequency' setting for additional constraints on
  when the Splunk platform logs certificate data. 
* Default: true

certLogMaxCacheEntries = <integer>
* The size of the cache for tracking certificate entries.
* The cache keeps track of the certificates for a time period of
  'certLogRepeatFrequency' to avoid generating duplicate logs.
* If the cache fills before the 'certLogRepeatFrequency' period elapses, the
  cache removes the entry with the oldest access time to make space.
* Update this setting as per the number of forwarders that are
  sending data to indexers. If the number of forwarders is larger than the
  cache size, some of the certificates might generate duplicate logs
  even though the previous log was within the 'certLogRepeatFrequency' period.
* When you restart Splunk Enterprise, the cache resets and the timer starts over.
* This setting takes effect only when 'logCertificateData' has a value of 'true'.
* Default: 10000

certLogRepeatFrequency = <timespan>
* The interval between writing repeat entries into the certificate data
  log for a certain certificate.
* This setting helps reduce certificate data log size by providing control
  over how often to log certificate data.
* When the Splunk platform receives a certificate the first time in a TLS
  connection, it adds the certificate to a cache. Subsequent connections
  with the same certificate won't generate a new entry to the log until
  a period of 'certLogRepeatFrequency' has passed. After this amount of
  time elapses, splunkd resets the log timestamp and writes another
  certificate log entry.
* The Splunk platform enforces this setting as long as the size of the cache
  does not reach 'certLogMaxCacheEntries'. When there are more than
  'certLogMaxCacheEntries', the cache removes the entry with the oldest
  access time to make space.
* When you restart Splunk Enterprise, the cache resets and the timer starts over.
* This setting takes effect only when 'logCertificateData' has a value of 'true'.
* A value of "0" means that the platform logs certificate data every time
  it receives a certificate.
* Default: 1d

sslCommonNameToCheck = <comma-separated list>
* Checks the common name of the client certificate against this list of names.
* If there is no match, assumes that the Splunk instance is not authenticated
  against this server.
* For this setting to work, you must also set 'requireClientCert' to "true".
* This setting is optional.
* Default: empty string (no common name checking)

sslAltNameToCheck = <comma-separated list>
* Checks the alternate name of the client certificate against this list of names.
* If there is no match, assumes that the Splunk instance is not authenticated
  against this server.
* For this setting to work, you must also set 'requireClientCert' to "true".
* This setting is optional.
* Default: empty string (no alternate name checking)

useSSLCompression = <boolean>
* Whether or not the server lets forwarders that connect to it negotiate SSL-
  layer data compression.
* A value of "true" means the server lets forwarders negotiate
  SSL-layer data compression.
* Default: The value of 'server.conf/[sslConfig]/allowSslCompression'

sslServerHandshakeTimeout = <integer>
* The timeout, in seconds, for an SSL handshake to complete between
  forwarder and the TCP input processor.
* If the TCP input processor does not receive a "Client Hello" from the forwarder
  within 'sslServerHandshakeTimeout' seconds, the server terminates
  the connection.
* Default: 60

############################################################################
# UDP (User Datagram Protocol network input):
############################################################################

[udp://<remote server>:<port>]
* Similar to the [tcp://] stanza, except that this stanza causes the Splunk
  instance to listen on a UDP port.
* Only 1 stanza per port number is currently supported.
* Configures the instance to listen on a specific port.
* If you specify <remote server>, the specified port only accepts data
  from that host.
* If <remote server> is empty - [udp://<port>] - the port accepts data sent
  from any host.
  * The use of <remote server> is not recommended. Use the 'acceptFrom'
    setting, which supersedes this setting.
* Generates events with source set to udp:portnumber, for example: udp:514
* If you do not specify a sourcetype, generates events with sourcetype set
  to udp:portnumber.

# Additional settings:

connection_host = [ip|dns|none]
* "ip" sets the host to the IP address of the system sending the data.
* "dns" sets the host to the reverse DNS entry for IP address of the system
  that sends the data. For this to work correctly, set the forward DNS lookup
  to match the reverse DNS lookup in your DNS configuration.
* "none" leaves the host as specified in inputs.conf, typically the Splunk
  system hostname.
* If the input is configured with a 'sourcetype' that has a transform that
  overrides the 'host' field e.g. 'sourcetype=syslog', that takes
  precedence over the host specified here.
* Default: ip

_rcvbuf = <integer>
* The receive buffer, in bytes, for the UDP port.
* If you set the value to 0 or a negative number, the input ignores the value.
* If the default value is too large for an OS, the instance tries to set
  the value to 1572864/2. If that value is also too large, the instance
  retries with 1572864/(2*2). It continues to retry by halving the value until
  it succeeds.
* Default: 1572864

no_priority_stripping = <boolean>
* Whether or not the input strips <priority> syslog fields from events it
  receives over the syslog input.
* A value of "true" means the instance does NOT strip the <priority>
  syslog field from received events.
* NOTE: Do NOT set this setting if you want to strip <priority>.
* Default: false

no_appending_timestamp = <boolean>
* Whether or not to append a timestamp and host to received events.
* A value of "true" means the instance does NOT append a timestamp
  and host to received events.
* NOTE: Do NOT set this setting if you want to append timestamp and host
  to received events.
* Default: false

queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB

persistentQueueSize = <integer>[KB|MB|GB|TB]
* The maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
  persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
  interact, search the online documentation for "persistent queues"..
* If you set this to a value other than 0, then 'persistentQueueSize' must
  be larger than either the in-memory queue size (as defined by the 'queueSize'
  setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
  server.conf).
* Default: 0 (no persistent queue)

listenOnIPv6 = [no|yes|only]
* Select whether the instance listens on the IPv4, IPv6, or both protocols.
* Set this to 'yes' to listen on both IPv4 and IPv6 protocols.
* Set to 'only' to listen on only the IPv6 protocol.
* If not present, the input uses the setting in the [general] stanza
  of server.conf.

acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]
  stanza.
* Default: "*" (accept from anywhere)

[udp:<port>]
* This input stanza is the same as [udp://<remote server>:<port>], but does
  not have a <remote server> restriction.
* See the documentation for [udp://<remote server>:<port>] to configure
  supported settings:

connection_host = [ip|dns|none]
_rcvbuf = <integer>
no_priority_stripping = <boolean>
no_appending_timestamp = <boolean>
queueSize = <integer>[KB|MB|GB]
persistentQueueSize = <integer>[KB|MB|GB|TB]

acceptFrom = <comma- or space-separated list>

############################################################################
# FIFO (First In, First Out queue):
############################################################################

[fifo://<path>]
* This stanza configures the monitoring of a FIFO at the specified path.

queueSize = <integer>[KB|MB|GB]
* Maximum size of the in-memory input queue.
* Default: 500KB

persistentQueueSize = <integer>[KB|MB|GB|TB]
* Maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
  persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
  interact, search the online documentation for "persistent queues"..
* If you set this to a value other than 0, then 'persistentQueueSize' must
  be larger than either the in-memory queue size (as defined by the 'queueSize'
  setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
  server.conf).
* Default: 0 (no persistent queue)

############################################################################
# Scripted Input:
############################################################################

[script://<cmd>]
* Runs <cmd> at a configured interval and indexes the output
  that <cmd> returns.
* To determine the interval at which the input runs <cmd>,
  use the 'interval' setting.
* The <cmd> must reside in one of the following directories:
  * $SPLUNK_HOME/etc/system/bin/
  * $SPLUNK_HOME/etc/apps/$<APPNAME>/bin/
  * $SPLUNK_HOME/bin/scripts/
* The path to <cmd> can be an absolute path, make use of an environment
  variable such as $SPLUNK_HOME, or use the special pattern of an initial '.'
  as the first directory to indicate a location inside the current app.
  For more scripted input examples, search the documentation for
  "Add a scripted input with inputs.conf."
* <cmd> can also be a path to a file that ends with a ".path" suffix. A file
  with this suffix is a special type of pointer file that points to a command
  to be run. Although the pointer file is bound by the same location
  restrictions mentioned previously, the command referenced inside it can
  reside anywhere on the file system. The .path file must contain exactly
  one line: the path to the command to run, optionally followed by command-line
  arguments. The file can contain additional empty lines and lines that begin
  with '#'. The input ignores these lines.

interval = [<decimal>|<cron schedule>]
* How often, in seconds, to run the specified command, or a valid "cron"
  schedule.
* If you specify the interval as a number, it may have a fractional
  component; for example, 3.14
* To specify a cron schedule, use the following format:
  * "<minute> <hour> <day of month> <month> <day of week>"
  * Cron special characters are acceptable. You can use combinations of "*",
  ",", "/", and "-" to specify wildcards, separate values, specify ranges
  of values, and step values.
* The cron implementation for data inputs does not currently support names
  of months or days.
* The special value "0" forces this scripted input to be run continuously.
  As soon as the script exits, the input restarts it.
* The special value "-1" causes the scripted input to run once on start-up.
* NOTE: when you specify a cron schedule, the input does not run the
  script on start-up.
* Default: 60.0

passAuth = <string>
* The user to run the script as.
* If you provide a username, the instance generates an auth token for that
  user and passes it to the script through the stdin data stream.
* No default.

python.version = [default|python|python2|python3|python3.7|python3.9|latest]
* For Python scripts only, selects which Python version to use.
* Set to either "default" or "python" to use the system-wide default Python
  version.
* Set to "python3" or "python3.7" to use the Python 3.7 version.
* Set to "python3.9" to use the Python 3.9 version.
* In the context of configuring apps, the "latest" value is not currently
  supported. It is related to a feature that is still under development.
* Optional.
* Default: Not set; uses the system-wide Python version.

queueSize = <integer>[KB|MB|GB]
* Maximum size of the in-memory input queue.
* Default: 500KB

persistentQueueSize = <integer>[KB|MB|GB|TB]
* Maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
  persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
  interact, search the online documentation for "persistent queues"..
* If you set this to a value other than 0, then 'persistentQueueSize' must
  be larger than either the in-memory queue size (as defined by the 'queueSize'
  setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
  server.conf).
* Default: 0 (no persistent queue)

index = <string>
* The index where the scripted input sends the data.
* The script passes this parameter as a command-line argument to <cmd> in
  the format: -index <index name>.
  If the script does not need the index info, it can ignore this argument.
* If you do not specify an index, the script uses the default index.

send_index_as_argument_for_path = <boolean>
* Whether or not to pass the index as an argument when specified for
  stanzas that begin with 'script://'
* A value of "true" means the script passes the argument as
  '-index <index name>'.
* To avoid passing the index as a command line argument, set this to "false".
* Default: true

start_by_shell = <boolean>
* Whether or not to run the specified command through the operating system
  shell or command prompt.
* A value of "true" means the host operating system runs the
  specified command through the OS shell ("/bin/sh -c" on *NIX,
  "cmd.exe /c" on Windows.)
* A value of "false" means the input runs the program directly
  without attempting to expand shell metacharacters.
* You might want to explicitly set a value of "false" for scripts
  that you know do not need UNIX shell metacharacter expansion. This is
  a Splunk best practice.
* Default (on *nix machines): true
* Default (on Windows machines): false

# File system change monitor (fschange monitor)
############################################################################
#
# The file system change monitor has been deprecated as of Splunk Enterprise
# version 5.0 and might be removed in a future version of the product.
#
# You cannot simultaneously monitor a directory with both the 'fschange'
# and 'monitor' stanza types.
#

[fschange:<path>]
* Monitors changes (such as additions, updates, and deletions) to this
  directory and any of its sub-directories.
* <path> is the direct path. Do not preface it with '//' like with
  other inputs.
* Sends an event for every change.

disabled = <boolean>
* Whether or not the file system change monitor input is active.
* Set a value of "true" to disable the input, and "false" to enable it.
* Default: false

# Additional settings:
# NOTE: The 'fschange' stanza type does not use the same settings as
# other input types. It uses only the following settings:

  set 'signedaudit' to "false"): _audit
* Default: (in all other cases): the default index

signedaudit = <boolean>
* Whether or not to send cryptographically signed add/update/delete events.
* A value of "true" means the input does the following to
  events that it generates:
  * Puts the events in the _audit index.
  * Sets the event sourcetype to 'audittrail'
* A value of "false" means the input:
  * Places events in the default index.
  * Sets the sourcetype to whatever you specify (or "fs_notification"
    by default).
* You must set 'signedaudit' to "false" if you want to set the index for
  fschange events.
* You must also enable auditing by using the audit.conf file.
* Default: false

filters = <comma-separated list>
* The fschange input applies each filter, left to right, for each file
  or directory found during the monitor poll cycle.
* See the "File System Monitoring Filters" section later in this file
  for help on how to define a fschange filter.

recurse = <boolean>
* Whether or not the fschange input should look through all sub-directories
  for changes to files in a directory.
* A value of "true" means the input searches recursively through
  sub-directories within the directory specified in [fschange].
* Default: true

followLinks = <boolean>
* Whether or not the fschange input follows any symbolic
  links it encounters.
* A value of "true" means the input follows symbolic links.
* CAUTION: Do not set this setting to "true" unless you can confirm that
  doing so will not create a file system loop (For example, in
  Directory A, symbolic link B points back to Directory A.)
* Default: false

pollPeriod = <integer>
* How often, in seconds, to check a directory for changes.
* Default: 3600 (1 hour)

hashMaxSize = <integer>
* The maximum size, in bytes, that a file can be for the fschange input to
  calculate a SHA256 hash for that file.
* Tells the fschange input to calculate a SHA256 hash for every file that
  is this size or smaller, in bytes.
* The input uses this hash as an additional method for detecting changes to the
  file or directory.
* Default: -1 (disabled)

fullEvent = <boolean>
* Whether or not to send the full event if the input detects an add or
  update change.
* Set to "true" to send the full event if an add or update change is detected.
* Further qualified by the 'sendEventMaxSize' setting.
* Default: false

sendEventMaxSize = <integer>
* The maximum size, in bytes, that an fschange event can be for the input to
  send the full event to be indexed.
* Limits the size of event data that the fschange input sends.
* This also limits the size of indexed file data.
* Default: -1 (unlimited)

sourcetype = <string>
* Sets the source type for events from this input.
* The input automatically prepends "sourcetype=" to <string>.
* Default (if you set the 'signedaudit' setting to "true"): audittrail
* Default (if you set the 'signedaudit' setting to "false"): fs_notification

host = <string>
* Sets the host name for events from this input.
* Default: whatever host sent the event

filesPerDelay = <integer>
* The number of files that the fschange input processes between processing
  delays, as specified by the 'delayInMills' setting.
* After a delay of 'delayInMills' milliseconds, the fschange input processes
  'filesPerDelay' files, then waits 'delayInMills' milliseconds again before
  repeating this process.
* This setting helps throttle file system monitoring so it consumes less CPU.
* Default: 10

delayInMills = <integer>
* The delay, in milliseconds, that the fschange input waits between
  processing 'filesPerDelay' files.
* After a delay of 'delayInMills' milliseconds, the fschange input processes
  'filesPerDelay' files, then waits 'delayInMills' milliseconds again before
  repeating this process.
* This setting helps throttle file system monitoring so it consumes less CPU.
* Default: 100


############################################################################
# File system monitoring filters:
############################################################################

[filter:<filtertype>:<filtername>]
* Defines a filter of type <filtertype> and names it <filtername>.
* <filtertype>:
  * Filter types are either 'blacklist' or 'whitelist.' 'blacklist' is the
    deny list filter type and 'whitelist' is the allow list filter type.
  * An allow list filter processes all file names that match the
    regular expression list that you define within the stanza.
  * A deny list filter skips all file names that match the
    regular expression list.
* <filtername>
  * The fschange input uses filter names that you specify with
    the 'filters' setting for a given fschange stanza.
  * You can specify multiple filters by separating them with commas.

regex<integer> = <regular expression>
* Deny list and allow list filters can include a set of regular expressions.
* The name of each regular expression MUST be 'regex<integer>', meaning the
  string "regex" and then an integer. <integer> starts at 1 and increments by 1.
* The input applies each regular expression in numeric order:
  regex1=<regular expression>
  regex2=<regular expression>
  ...

* No default.

maxSockets = <integer>
* The number of HTTP connections that the HTTP event collector input
  accepts simultaneously.
* Set this setting to constrain resource usage.
* If you set this setting to 0, the input automatically sets it to
  one third of the maximum allowable open files on the host.

  connections.
* Default: 0

maxThreads = <integer>
* The number of threads that can be used by active HTTP transactions.
* Set this to constrain resource usage.
* If you set this setting to 0, the input automatically sets the limit to
  one third of the maximum allowable threads on the host.

* If set to a negative value, the input does not enforce a limit on threads.
* Default: 0

rollingRestartReturnServerBusy = <boolean>
* Whether or not HTTP Event Collector endpoints return HTTP errors 404 (not found) or 503 (server busy)
  when a client connects to an indexer that is currently shutting down during a rolling restart.
* This setting applies to instances on the Classic Experience only.
* NOTE: Do not change this setting unless instructed to do so by Splunk Support.
* Default: true

keepAliveIdleTimeout = <integer>
* How long, in seconds, that the HTTP Event Collector input lets a keep-alive
  connection remain idle before forcibly disconnecting it.
* If this value is less than 7200, the input sets it to 7200.
* Default: 7200

busyKeepAliveIdleTimeout = <integer>
* How long, in seconds, that the HTTP Event Collector lets a keep-alive
  connection remain idle while in a busy state before forcibly disconnecting it.
* CAUTION: Setting this to a value that is too large
  can result in file descriptor exhaustion due to idling connections.
* If this value is less than 12, the input sets it to 12.
* Default: 12

serverCert = <string>
* The full path to the server certificate PEM format file.
* The same file may also contain a private key.
* Splunk software automatically generates certificates when it first
  starts.
* You may replace the auto-generated certificate with your own certificate.
* Default: $SPLUNK_HOME/etc/auth/server.pem

sslKeysfile = <string>
* DEPRECATED.
* Use the 'serverCert' setting instead.

  (Certificate Authority) certificate PEM format file that contains one or
  more certificates concatenated together.
* Default: cacert.pem

caPath = <string>

* Use absolute paths for all certificate files.
* If certificate files given by other settings in this stanza are not absolute
  paths, then they are relative to this path.
* Default: $SPLUNK_HOME/etc/auth

sslVersions = <comma-separated list>
* A comma-separated list of SSL versions to support.
* The versions available are "ssl3", "tls1.0", "tls1.1", and "tls1.2"
* The special version "*" selects all supported versions. The version "tls"
  selects all versions "tls1.0" or newer.
* To remove a version from the list, prefix it with "-".
* SSLv2 is always disabled. Specifying "-ssl2" in the version list
  has no effect.
* When configured in Federal Information Processing Standard (FIPS) mode, the
  "ssl3" version is always disabled, regardless of this configuration.
* Default: *,-ssl2  (anything newer than SSLv2)

cipherSuite = <string>
* The cipher string to use for the HTTP Event Collector input.
* Use this setting to ensure that the server does not accept connections using
  weak encryption protocols.
* If you set this setting, the input uses the specified cipher string for
  the HTTP server.
* Default: The default cipher string that 'OpenSSL' provides

sslServerHandshakeTimeout = <integer>
* The timeout, in seconds, for an SSL handshake to complete between an
  HEC client and the Splunk HEC server.

  'sslServerHandshakeTimeout' seconds, the server terminates
  the connection.
* Default: 60

listenOnIPv6 = [no|yes|only]
* Whether or not this input listens on IPv4, IPv6, or both.
* Set to "no" to make the input listen only on the IPv4 protocol.
* Set to "yes" to make the input listen on both IPv4 and IPv6 protocols.
* Set to "only" to make the input listen on only the IPv6 protocol.
* Default: The setting in the [general] stanza of the server.conf file

acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]
  stanza.
* Default: "*" (accept from anywhere)

requireClientCert = <boolean>
* Requires that any client connecting to the HEC port has a certificate that
  can be validated by the certificate authority specified in the
  'caCertFile' setting.
* Default: false

ecdhCurveName = <string>
* DEPRECATED.
* Use the 'ecdhCurves' setting instead.
* This setting specifies the ECDH curve to use for ECDH key negotiation.
* Splunk software only supports named curves that have been specified by their
  SHORT names.
* The list of valid named curves by their short or long names

  $SPLUNK_HOME/bin/splunk cmd openssl ecparam -list_curves
* Default: empty string

ecdhCurves = <comma-separated list>
* ECDH curves to use for ECDH key negotiation.
* The curves should be specified in the order of preference.
* The client sends these curves as a part of Client Hello.
* The server supports only the curves specified in the list.
* Splunk software only supports named curves that have been specified by their
  SHORT names.
* The list of valid named curves by their short or long names can be obtained
  by executing this command:
  $SPLUNK_HOME/bin/splunk cmd openssl ecparam -list_curves
* Example setting: ecdhCurves = prime256v1,secp384r1,secp521r1
* Default: empty string

crossOriginSharingPolicy = <origin_acl> ...
* A list of the HTTP Origins for which to return Access-Control-Allow-*
  Cross-origin Resource Sharing (CORS) headers.
* These headers tell browsers that web applications at those sites
  can be trusted to make requests to the REST interface.
* The origin is passed as a URL without a path component (for example
  "https://app.example.com:8000").
* This setting can take a list of acceptable origins, separated
  by spaces and/or commas.
* Each origin can also contain wildcards for any part.  Examples:
    * *://app.example.com:*  (either HTTP or HTTPS on any port)
    * https://*.example.com  (any host under example.com, including
      example.com itself).
* An address can be prefixed with a '!' to negate the match, with
  the first matching origin taking precedence. Example:
    * "!*://evil.example.com:* *://*.example.com:*" to not avoid
      matching one host in a domain.
* "*" matches all origins.
* Default: empty string

crossOriginSharingHeaders = <string>
* A list of the HTTP headers to which splunkd sets
  "Access-Control-Allow-Headers" when replying to
  Cross-Origin Resource Sharing (CORS) preflight requests.
* The "Access-Control-Allow-Headers" header is used in response to
  a CORS preflight request to tell browsers which HTTP headers can be
  used during the actual request.
* A CORS preflight request is a CORS request that checks to see if
  the CORS protocol is understood and a server is aware of using
  specific methods and headers.
* This setting can take a list of acceptable HTTP headers, separated
  by commas.
* A single "*" can also be used to match all headers.
* Default: empty string

forceHttp10 = [auto|never|always]
* Whether or not the REST HTTP server forces clients that connect
  to it to use the HTTP 1.0 specification for web communications.
* When set to "always", the REST HTTP server does not use some
  HTTP 1.1 features such as persistent connections or chunked
  transfer encoding.
* When set to "auto", it does this only if the client did not send
  a User-Agent header, or if the user agent is known to have bugs
  in its support of HTTP/1.1.
* When set to "never" it always allows HTTP 1.1, even to
  clients it suspects might be buggy.
* Default: auto

sslCommonNameToCheck = <comma-separated list>
* A list of SSL Common Names to match against certificates that incoming
  HTTPS connections present to this instance.
* If you configure this setting and also set 'requireClientCert' to "true",
  splunkd limits most inbound HTTPS connections to hosts that use
  a cert with one of the listed common names.
* The most important scenario to use this setting is distributed search.
* This feature does not work with the deployment server and client
  communication over SSL.
* This setting is optional.
* Default: empty string (no common name checking)

sslAltNameToCheck = <comma-separated list>
* If you set this setting and also set 'requireClientCert' to true,
  splunkd can verify certificates that have a so-called
  "Subject Alternate Name" that matches any of the alternate
  names in this list.
  * Subject Alternate Names are effectively extended descriptive
    fields in SSL certs beyond the commonName. A common practice for
    HTTPS certs is to use these values to store additional valid
    hostnames or domains where the cert should be considered valid.
* Accepts a comma-separated list of Subject Alternate Names to consider
  valid.
* Items in this list are never validated against the SSL Common Name.
* This feature does not work with the deployment server and client
  communication over SSL.
* This setting is optional.
* Default: empty string (no alternate name checking)

sendStrictTransportSecurityHeader = <boolean>
* Whether or not to force inbound connections to always use SSL with
  the "Strict-Transport-Security" header..
* If set to "true", the REST interface sends a "Strict-Transport-Security"
  header with all responses to requests made over SSL.
* This can help prevent a client being tricked later by a Man-In-The-Middle
  attack to accept a non-SSL request. However, this requires a commitment that
  no non-SSL web hosts will ever be run on this hostname on any port. For
  example, if Splunk Web is in default non-SSL mode this can break the
  ability of the browser to connect to it. Enable with caution.
* Default: false

allowSslCompression = <boolean>
* Whether or not to allow data compression over SSL.
* If set to "true", the server allows clients to negotiate
  SSL-layer data compression.
* Default: true

allowSslRenegotiation = <boolean>
* Whether or not to let SSL clients renegotiate their connections.
* In the SSL protocol, a client may request renegotiation of the connection
  settings from time to time.
* Setting this to false causes the server to reject all renegotiation
  attempts, which breaks the connection.
* This limits the amount of CPU a single TCP connection can use, but it can
  cause connectivity problems, especially for long-lived connections.
* Default: true

ackIdleCleanup = <boolean>
* Whether or not to remove ACK channels that have been idle after a period
  of time, as defined by the 'maxIdleTime' setting.
* A value of "true" means the server removes the ACK channels that are idle
  for 'maxIdleTime' seconds.
* Default: true

maxIdleTime = <integer>
* The maximum amount of time, in seconds, that ACK channels can be idle
  before they are removed.
* If 'ackIdleCleanup' is "true", the system removes ACK channels that have
  been idle for 'maxIdleTime' seconds.
* Default: 600 (10 minutes)

channel_cookie = <string>
* The name of the cookie to use when sending data with a specified channel ID.
* The value of the cookie is the channel sent. For example, if you have
  set 'channel_cookie=foo' and sent a request with channel ID set to 'bar',
  then you will have a cookie in the response with the value 'foo=bar'.
* If no channel ID is present in the request, then no cookie is returned.
* This setting is to be used for load balancers (for example, AWS ELB) that can
  only provide sticky sessions on cookie values and not general header values.
* If no value is set (the default), then no cookie is returned.
* Default: empty string (no cookie)

maxEventSize = <positive integer>[KB|MB|GB]
* The maximum size of a single HEC (HTTP Event Collector) event.
* HEC disregards and triggers a parsing error for events whose size is
  greater than 'maxEventSize'.
* Default: 5MB


route = [has_key|absent_key:<key>:<queueName>;...]
* See 'route' in the "[splunktcp]" stanza for
  information on this setting.

* Default: 0 (enabled)

description = <string>
* A human-readable description of this token.
* Default: empty string

indexes = <comma-separated list>
* The indexes that events for this token can go to.
* If you do not specify this value, the index list is empty, and any index
  can be used.
* Separate multiple indexes with commas.
* The Splunk platform accepts and indexes events without a specified
  index to a default index.
* No default.

s2s_indexes_validation = [ disabled | disabled_for_internal | enabled_for_all ]
* The method of index validation for Splunk-to-Splunk (S2S) events for this
  token.
* A value of "disabled" means the Splunk platform doesn't validate the
  event's index and the "indexes" setting has no effect for the S2S events.
* A value of "disabled_for_internal" means the Splunk platform doesn't
  validate internal indexes and allows all S2S events destined for them. The
  platform validates other indexes according to the "indexes" setting.
* A value of "enabled_for_all" means the platform validates all indexes
  according to the "indexes" setting.
* The platform silently drops rejected events.
* Default: disabled_for_internal

index = <string>

* Default: the default index

sourcetype = <string>
* The default sourcetype to use if it is not specified in an event.
* Default: empty string

  be larger than either the in-memory queue size (as defined by the
  'queueSize' setting in inputs.conf or 'maxSize' settings in [queue] stanzas
  in server.conf).
* Default: 0 (no persistent queue)

connection_host = [ip|dns|proxied_ip|none]
* Specifies the host if an event doesn't have a host set.
* "ip" sets the host to the IP address of the system sending the data.
* "dns" sets the host to the reverse DNS entry for IP address of the system
  that sends the data. For this to work correctly, set the forward DNS lookup
  to match the reverse DNS lookup in your DNS configuration.
* "proxied_ip" checks whether an X-Forwarded-For header was sent
  (presumably by a proxy server) and if so, sets the host to that value.
  Otherwise, the IP address of the system sending the data is used.
* "none" leaves the host as specified in the HTTP header.
* No default.

useACK = <boolean>
* When set to "true", acknowledgment (ACK) is enabled. Events in a request
  are tracked until they are indexed. An events status (indexed or not) can be

* This setting can be set at the stanza level.
* Default: false

allowQueryStringAuth = <boolean>
* Enables or disables sending authorization tokens with a query string.
* This is a token level configuration. It may only be set for
  a particular token.
* To use this feature, set to "true" and configure the client application to
  include the token in the query string portion of the URL they use to send
  data to HEC in the following format:
  "https://<URL>?<your=query-string>&token=<your-token>" or
  "https://<URL>?token=<your-token>" if the token is the first element in the
  query string.
* If a token is sent in both the query string and an HTTP header, the token in
  the query string takes precedence, even if this feature is disabled. In
  other words, if a token is present in the query string, any token in the
  header for that request is not used.
* NOTE: Query strings may be observed in transit and/or logged in cleartext.
  There is no confidentiality protection for the transmitted tokens.
    * Before using this in production, consult security personnel in your
      organization to understand and plan to mitigate the risks.
    * At a minimum, always use HTTPS when you enable this feature. Check your
      client application, proxy, and logging configurations to confirm that
      the token is not logged in clear text.
    * Give minimal access permissions to the token in HEC and restrict the
      use of the token only to trusted client applications.
* Default: false

# WINDOWS INPUTS:
############################################################################*

* Windows platform specific input processor.
# ***********
# Splunk software on Windows ships with several Windows-only inputs. They are
# defined in the default inputs.conf.

* Use the "disabled=" setting to enable/disable any of them.
* A short summary of the inputs follows:
  * Perfmon: Monitors Windows performance counters, objects, and instances.
  * WinRegMon: Tracks and report any changes that occur in the
    local system Registry.
  * ADMon: Indexes existing Active Directory (AD) objects and listens for AD
    changes.
  * WMI: Retrieves event logs remotely and locally through the Windows
    Management Instrumentation subsystem. It can also gather performance
    data remotely, as well as receive various system notifications. See
    wmi.conf.spec for information on how to configure this input.

#*******
# The following Windows input specifications are for parsing on non-Windows
# platforms.

############################################################################
# Performance Monitor
############################################################################

[perfmon://<name>]

* This section explains possible settings for configuring
  the Windows Performance Monitor input.
* Each perfmon:// stanza represents an individually configured performance
  monitoring input. If you configure the input through Splunk Web, then the
  value of "<NAME>" matches what was specified there. While you can add
  performance monitor inputs manually, it is a best practice to use Splunk
  Web to configure them, because it is easy to mistype the values for
  Performance Monitor objects, counters, and instances.
* NOTE: The perfmon stanza is for local systems ONLY. To define performance
  monitor inputs for remote machines, use wmi.conf.

object = <string>
* A valid Performance Monitor object as defined within Performance
  Monitor (for example, "Process," "Server," "PhysicalDisk").
* You can specify a single valid Performance Monitor object or use a
  regular expression (regex) to specify multiple objects.
* This setting is required, and the input does not run if the setting is
  not present.
* No default.

counters = <semicolon-separated list>
* This can be a single counter, or multiple valid Performance Monitor
  counters.
* This setting is required, and the input does not run if the setting is
  not present.
* "*" is equivalent to all available counters for a given Performance
  Monitor object.
* No default.

nonmetric_counters = <semicolon-separated list>
* A list of performance counters on which the performance monitor input
  must not perform sampling.
* When the input retrieves the value for a counter that is in this list,
  it returns the latest value it retrieves, rather than an average of
  the values that it got over the sampling interval, as defined by the
  'samplingInterval' setting.
* Add counters to this setting in cases where the values that the input
  returns for a setting would be incorrect if it were averaged over a
  'samplingInterval', or where average, minimum, or maximum values for a
  counter would not be of any interest.
* As an example, the "ID Process" counter works better as a non metric counter
  because the most recent measurement of the counter is more relevant
  than the average of any measurements of that counter.
* No default.

instances = <semicolon-separated list>
* One or more multiple valid Performance Monitor instances.
* "*" is equivalent to all available instances for a given Performance Monitor
  counter.
* If applicable instances are available for a counter and this setting is not
  present, then the input logs data for all available instances (this is the
  same as setting "instances = *").
* If there are no applicable instances for a counter, then you can omit
  this setting.
* No default.

interval = <integer>
* How often, in seconds, to poll for new data.
* This setting is required, and the input does not run if the setting is
  not present.
* The recommended setting depends on the Performance Monitor object,
  counter(s), and instance(s) that you define in the input, and how much
  performance data you need.
  * Objects with numerous instantaneous or per-second counters, such
    as "Memory", "Processor", and "PhysicalDisk" should have shorter
    interval times specified (anywhere from 1-3 seconds).
  * Less volatile counters such as "Terminal Services", "Paging File",
    and "Print Queue" can have longer intervals configured.
* Default: 300

mode = [single|multikv]
* Specifies how the performance monitor input generates events.
* Set to "single" to print each event individually.
* Set to "multikv" to print events in multikv (formatted multiple
  key-value pair) format.
* Default: single

samplingInterval = <positive integer>
* How often, in milliseconds, to poll for new data.
* This is an advanced setting.
* Enables high-frequency performance sampling. The input collects
  performance data every sampling interval. It then reports averaged data
  and other statistics at every interval.
* The minimum legal value is 100, and the maximum legal value must be less
  than the 'interval' setting.
* If not set, high-frequency sampling does not occur.
* No default (disabled).

stats = <average;count;dev;min;max>
* Reports statistics for high-frequency performance sampling.
* This is an advanced setting.
* Setting a 'samplingInterval' is required to use 'stats'.
* Acceptable values are: average, count, dev, min, max.
* You can specify multiple values by separating them with semicolons.
* Adds new fields that append the stats function name.
  Setting 'average' replaces the stats displayed in the default field.
* No default. (disabled)

disabled = <boolean>
* Specifies whether or not the input is enabled.
* Set to 1 to disable the input, and 0 to enable it.
* Default: 0 (enabled)

showZeroValue = <boolean>
* Specifies whether or not the input collects zero-value event data.
* Set to 1 to capture zero value event data, and 0 to ignore such data.
* Default: 0 (ignore zero value event data)

useEnglishOnly = <boolean>
* Controls which Windows Performance Monitor API the input uses.
* If set to "true", the input uses PdhAddEnglishCounter() to add the
  counter string. This ensures that counters display in English
  regardless of the Windows machine locale.
* If set to "false", the input uses PdhAddCounter() to add the counter string.
* NOTE: if you set this setting to true, the 'object' setting does not
  accept a regular expression as a value on machines that have a non-English
  locale.
* Default: false

useWinApiProcStats = <boolean>
* Whether or not the Performance Monitor input uses process kernel mode and
  user mode times to calculate CPU usage for a process, rather than using
  the standard Performance Data Helper (PDH) APIs to calculate those values.
* A problem was found in the PDH APIs that causes Performance Monitor inputs
  to show maximum values of 100% usage for a process on multicore Windows
  machines, even when the process uses more than 1 core at a time.
* When you configure this setting to "true", the input uses the
  GetProcessTime() function in the core Windows API to calculate
  CPU usage for a process, for the following Performance Monitor
  counters, only:
** Processor Time
** User Time
** Privileged Time
* This means that, if a process uses 5 of 8 cores on an 8-core machine, that
  the input should return a value of around 500, rather than the incorrect 100.
* When you configure the setting to "false", the input uses the standard
  PDH APIs to calculate CPU usage for a process. On multicore systems, the
  maximum value that PDH APIs return is 100, regardless of the number of
  cores in the machine that the process uses.
* Performance monitor inputs use the PDH APIs for all other Performance
  Monitor counters. Configuring this setting has no effect on those counters.
* NOTE: If the Windows machine uses a non-English system locale, and you
  have set 'useWinApiProcStats' to "true" for a Performance Monitor input,
  then you must also set 'useEnglishOnly' to "true" for that input.
* Default: false

formatString = <string>
* Controls the print format for double-precision statistic counters.
* Do not use quotes when specifying this string.
* Default: %.20g

usePDHFmtNoCap100 = <boolean>
* Whether or not performance counter values that are greater than 100 (for example,
  counter values that measure the processor load on computers with multiple
  processors) are reset to 100.
* If set to "true", the counter values can exceed 100.
* If set to "false", the input resets counter values to 100 if the
  processor load on multiprocessor computers exceeds 100.
* Default: false

############################################################################
# Direct Access File Monitor
############################################################################

# For Windows systems only.
# Does not use file handles

[MonitorNoHandle://<path>]

* This input intercepts file writes to the specific file.
* <path> must be a fully qualified path name to a specific file. Wildcards
  and directories are not accepted.
* This input type does not function on *nix machines.
* You can specify more than one stanza of this type.

disabled = <boolean>
* Whether or not the input is enabled.
* Default: 0 (enabled)

index = <string>
* Specifies the index where this input sends the data.
* This setting is optional.
* Default: the default index

############################################################################
# Windows Event Log Monitor
############################################################################

[WinEventLog://<name>]

* This section explains possible settings for configuring the
  Windows Event Log monitor.
* Each WinEventLog:// stanza represents an individually configured WinEventLog
  monitoring input. If you you configure the input through Splunk Web, the
  value of "<NAME>" matches what was specified there. While you can add
  event log monitor inputs manually, it is best practice to use Splunk
  Web to configure Windows event log monitor inputs because it is
  easy to mistype the values for event log channels.
* NOTE: The WinEventLog stanza is for local systems ONLY. To define event log
  monitor inputs for remote machines, use wmi.conf.

start_from = <string>
* How the Event Log input is to chronologically read the Event Log channels.
* A value of "oldest" means that the input reads Windows event logs
  from the oldest to the most recent.
* A value of "newest" means that the input reads Windows event logs
  in reverse, from the most recent to the oldest. After the input consumes
  the backlog of events, it stops.
* If you set this setting to "newest", and at the same time give the
  'current_only' setting a value of "false", the combination can result in the
  input indexing duplicate events.
* Do not set this setting to "newest" and at the same time give the
  'current_only' setting a value of "true". This results in the input not 
  collecting any events because you told it to read existing events
  from newest to oldest and read only incoming events concurrently, which
  is a logically impossible combination.
* Default: oldest

use_old_eventlog_api = <boolean>
* Whether or not to read Event Log events with the Event Logging API.
* This is an advanced setting. Contact Splunk Support before you change it.
* A value of "true" means the input uses the Event Logging API (instead of the
  Windows Event Log API) to read from the Event Log on Windows Server 2008,
  Windows Vista, and later installations.
* Default: false (Use the API that is specific to the OS)

use_threads = <integer>
* Specifies the number of threads, in addition to the default writer thread,
  that can be created to filter events with the deny list/allow list
  regular expression.
* This is an advanced setting. Contact Splunk Support before you change it.
* The maximum number of threads is 15.
* Default: 0

thread_wait_time_msec = <integer>
* The interval, in milliseconds, between attempts to re-read Event Log files
  when a read error occurs.
* This is an advanced setting. Contact Splunk Support before you change it.
* Default: 5000

#
# NOTE: The 'suppress_*' settings are similar to, but operate differently than,
# the 'evt_exclude_fields' setting. The 'suppress_*' settings avoid using the
# Windows API to gather Windows events that match the available
# fields, which helps with CPU performance. The 'evt_exclude_fields'
# is valid for all Windows Event Log fields, and while it does use
# the Windows API for all transactions, it discards the fields in
# each event that match, which helps reduce total data ingestion.
#

suppress_checkpoint = <boolean>
* Whether or not the Event Log strictly follows the 'checkpointInterval'
  setting when it saves a checkpoint.
* This is an advanced setting. Contact Splunk Support before you change it.
* By default, the Event Log input saves a checkpoint from between zero
  and 'checkpointInterval' seconds, depending on incoming event volume.
  If you set this setting to "true", that does not happen.
* Default: false

suppress_sourcename = <boolean>
* Whether or not to exclude the 'sourcename' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'sourcename' field from events
  and thruput performance (the number of events processed per second) improves.
* Default: false

suppress_keywords = <boolean>
* Whether or not to exclude the 'keywords' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'keywords' field from events and
  thruput performance (the number of events processed per second) improves.
* Default: false

suppress_type = <boolean>
* Whether or not to exclude the 'type' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'type' field from events and
  thruput performance (the number of events processed per second) improves.
* Default: false

suppress_task = <boolean>
* Whether or not to exclude the 'task' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'task' field from events and
  thruput performance (the number of events processed per second) improves.
* Default: false

suppress_opcode = <boolean>
* Whether or not to exclude the 'opcode' field from events.
  When set to true, the input excludes the 'opcode' field from events and
  thruput performance (the number of events processed per second) improves.
* This is an advanced setting. Contact Splunk Support before you change it.
* Default: false

current_only = <boolean>
* Whether or not to acquire only events that arrive while the instance is 
  running.
* A value of "true" means the input only acquires events that arrive
  while the instance runs and the input is on. The input does not read
  data which was stored in the Windows Event Log while the instance was not
  running. This means that there will be gaps in the data if you restart the
  instance or experiences downtime.
* A value of "false" means the input first gets all existing events
  that are stored in the log which have higher event IDs (have arrived more
  recently) than the most recent events acquired. The input then monitors
  events that arrive in real time.
* If you set this setting to "false", and at the same time set the
  'start_from' setting to "newest", the combination can result in the
  indexing of duplicate events.
* Do not set this setting to "true" and at the same time set the
  'start_from' setting to "newest". This results in the input not collecting
  any events because you told it to read existing events from oldest
  to newest and read only incoming events concurrently, which is a 
  logically impossible combination.
* Default: false (Gather stored events with higher event IDs first before 
  monitoring live events)

batch_size = <integer>
* How many Windows Event Log items to read per request.
* If troubleshooting identifies that the Event Log input is a bottleneck in
  acquiring data, increasing this value can help.
  * NOTE: Splunk Support has seen cases where large values can result in a
    stall in the Event Log subsystem. If you increase this value
    significantly, monitor closely for trouble.
* In local and customer acceptance testing, a value of 10 was acceptable
  for both throughput and reliability.
* Default: 10

checkpointInterval = <integer>
* How often, in seconds, that the Windows Event Log input saves a checkpoint.
* Checkpoints store the eventID of acquired events. This lets the input
  continue monitoring at the correct event after a shutdown or outage.
* Default: 0

checkpointSync = <boolean>
* Determines whether the input processor forces writing a checkpoint file to disk
  immediately or lets the operating system handle when writing of the
  file to disk occurs.
* A value of "true" means the input processor triggers writing of a checkpoint
  file to disk immediately. It also saves the file to a temporary location and
  renames it instead of overwriting the existing file.
* Default: false

channel_wait_time = <integer>
* How long, in seconds, that the Windows Event Log input waits for an Event Log
  channel that is not available to become available again.
* Some Event Log channels, like the Windows Defender channel, become
  unavailable during a Windows Defender Platform update and it takes
  some time to become available again.
* If the Event Log input is unable to collect event logs from a certain
  Event Log channel, change this setting to an appropriate value.
  For example, if the input does not collect Windows Defender event logs
  after a Windows Defender Platform update, increase this value.
* The maximum wait time is 180 (3 minutes).
* Default: 0

disabled = <boolean>
* Whether or not the input is enabled.
* Set to 1 to disable the input, and 0 to enable it.
* Default: 0 (enabled)

evt_resolve_ad_obj = <boolean>
* How the input should interact with Active Directory while indexing Windows
  Event Log events.
* If you set this setting to true, the input resolves the Active
  Directory Security IDentifier (SID) objects to their canonical names for
  a specific Windows Event Log channel.
* If you enable the setting, the rate at which the input reads events
  on high-traffic Event Log channels can decrease. Latency can also increase
  during event acquisition. This is due to the overhead involved in performing
  AD translations.
* When you set this setting to true, you can optionally specify the domain
  controller name or dns name of the domain to bind to with the 'evt_dc_name'
  setting. The input connects to that domain controller to resolve the AD
  objects.
* If you set this setting to false, the input does not attempt any resolution.
* Default: false (disabled) for all channels

evt_skip_GUID_resolution = <comma-separated list>
* A list of Windows Event Codes for which the Splunk platform does not contact
  the domain controller to resolve global unique identifiers (GUIDs) that
  are withing the event.
* Separate multiple event IDs or event ID ranges with commas. 
* If the event code matches an event, The Splunk platform does not contact 
  the DC to resolve any GUIDs in this event.
* This setting only takes effect if 'evt_resolve_ad_obj' has a value of "true".
* If 'evt_resolve_ad_obj' has a value of "false", this setting has no effect.
* This setting has no effect on SID resolution.
* See 'Event ID list format' later in this file for the proper 
  formatting of the event list.
* Default: none

evt_dc_name = <string>
* Which Active Directory domain controller to bind to for AD object
  resolution.
* If you prefix a dollar sign to a value (for example, $my_domain_controller),
  the input interprets the value as an environment variable. If the
  environment variable has not been defined on the host, it is the same
  as if the value is blank.
* This setting is optional.
* This setting can be set to the NetBIOS name of the domain controller
  or the fully-qualified DNS name of the domain controller. Either name
  type can, optionally, be preceded by two backslash characters. The following
  examples represent correctly formatted domain controller names:

    * "FTW-DC-01"
    * "\\FTW-DC-01"
    * "FTW-DC-01.splunk.com"
    * "\\FTW-DC-01.splunk.com"
    * $my_domain_controller

evt_dns_name = <string>
* The fully-qualified DNS name of the domain that the input should bind to for
  AD object resolution.
* This setting is optional.

evt_resolve_ad_ds = [auto|PDC]
* How the input should choose the domain controller to bind for
  AD resolution.
* This setting is optional.
* If set to PDC, the input only contacts the primary domain controller
  to resolve AD objects.
* If set to auto, the input lets Windows chose the best domain controller.
* If you set the 'evt_dc_name' setting, the input ignores this setting.
* Default: auto (let Windows determine the domain controller to use)

evt_ad_cache_disabled = <boolean>
* Enables or disables the AD object cache.
* Default: false (enabled)

evt_ad_cache_exp = <integer>
* The expiration time, in seconds, for AD object cache entries.
* This setting is optional.
* Default: 3600 (1 hour)

evt_ad_cache_exp_neg = <integer>
* The expiration time, in seconds, for negative AD object cache entries.
* This setting is optional.
* Default: 10

evt_ad_cache_max_entries = <integer>
* The maximum number of AD object cache entries.
* This setting is optional.
* Default: 1000

evt_exclude_fields = <comma-separated list>
* A list of valid Windows Event Log fields to exclude from Windows
  Event Log events.
* Specify fields that you want excluded from each event report.
* Do not exclude fields that you have also added to allow lists or
  deny lists. If fields are present in both, then 'evt_exclude_fields'
  excludes those fields, regardless of their presence in the allow list
  or deny list and the allow list or deny list will not behave as
  expected. The input logs an error to splunkd.log in this case.
* This setting is similar to, but operates differently than, the
  'suppress_*' settings. The 'suppress_*' settings avoid using the
  Windows API to gather Windows events that match the available
  fields, which helps with CPU performance. The 'evt_exclude_fields'
  is valid for all Windows Event Log fields, and while it does use
  the Windows API for all transactions, it discards the fields in
  each event that match, which helps reduce total data ingestion.
* Does not effect event report if 'renderXML' is set to "true".
* The 'evt_exclude_fields' setting is valid for all Windows Event Log fields.
* No default.

evt_sid_cache_disabled = <boolean>
* Enables or disables account Security IDentifier (SID) cache.
* This setting is global. It affects all Windows Event Log stanzas.
* Default: 0

evt_sid_cache_exp = <unsigned integer>
* The expiration time, in seconds, for account SID cache entries.
* This setting is global. It affects all Windows Event Log stanzas.
* This setting is optional.
* Default: 3600

evt_sid_cache_exp_neg = <unsigned integer>
* The expiration time, in seconds, for negative account SID cache entries.
* This setting is optional.
* This setting is global. It affects all Windows Event Log stanzas.
* Default: 10

evt_sid_cache_max_entries = <unsigned integer>
* The maximum number of account SID cache entries.
* This setting is global. It affects all Windows Event Log stanzas.
* This setting is optional.
* Default: 10

wec_event_format = [raw_event|rendered_event]
* The content format of the events that the Splunk platform expects to receive
  from a Windows Event Collector (WEC) subscription, before WEC sends the
  events to their destination log, for example, a Windows Event Log channel.
* This setting helps associate incoming WEC event formats with the Splunk
  platform internal interpretation before the platform looks up pre-rendered
  messages in Windows event logs.
* If the WEC subscription that targets this channel has its 'content Format'
  set to "Events", then set 'wec_event_format' to "raw_event".
* If the WEC subscription that targets this channel has its 'content Format'
  set to "RenderedText", then set 'wec_event_format' to "rendered_event".
* If multiple WEC subscriptions share the same value for the 'destination log'
  setting, but have different 'content Format' values, you have two options: 
  * You can update the WEC subscriptions so that they share the same values for 
    'content format'.
  * Or you can create custom ForwardedEvents channels for each WEC 
    subscription, point each WEC subscription to a custom ForwardedEvents 
    channel, and set equivalent values for 'wec_event_format' as described 
    previously.
* If Windows Event Collector does not forward these events, this setting is 
  optional.
* NOTE: You must restart the Splunk platform when you update WEC subscriptions,
  to synchronize with the new subscription configuration.
* Default (for 'ForwardedEvents' and custom channels named 'ForwardedEvents-1',
  'ForwardedEvents-2', etc.): rendered_event
* Default (for all other channels): raw_event

index = <string>
* Specifies the index that this input should send the data to.
* This setting is optional.
* Default: The default index

* These settings are optional.
* Both numbered and unnumbered allow lists and deny lists support two formats:
  * A comma-separated list of event IDs.
  * A list of key=regular expression pairs.
  * You cannot combine these formats. You can use either format on a specific
    line.

* Numbered allow list settings are permitted from 1 to 9, so whitelist1 through
  whitelist9 and blacklist1 through blacklist9 are supported.
* If no allow list or deny  list rules are present, the input reads all events.

############################################################################
# Event Log allow list and deny list formats
############################################################################

* Event ID list format:
  * A comma-separated list of terms.
  * Terms may be a single event ID (e.g. 6) or range of event IDs (e.g. 100-200)
  * Example: 4,5,7,100-200
    * This applies to events with IDs 4, 5, 7, or any event ID between 100
      and 200, inclusive.
  * A single asterisk (*) means all event codes.
  * The event ID list format provides no additional functionality over the
    key=regex format, but can be easier to understand:
    List format:      4,5,7,100-200
    Regex equivalent: EventCode=%^(4|5|7|1..|200)$%

* key=regex format:
  * A whitespace-separated list of Event Log components to match, and
    regular expressions to match against against them.
  * There can be one match expression or multiple expressions per line.
  * The key must belong to the set of valid keys provided in the "Valid
    keys for the key=regex format" section.
  * The regex consists of a leading delimiter, the regex expression, and a
    trailing delimiter. Examples: %regex%, *regex*, "regex"
  * When multiple match expressions are present, they are treated as a
    logical AND.  In other words, all expressions must match for the line to
    apply to the event.
  * If the value represented by the key does not exist, it is not considered
    a match, regardless of the regex.
  * Example:
    whitelist = EventCode=%^200$% User=%jrodman%
    Include events only if they have EventCode 200 and relate to User jrodman

# Valid keys for the key=regex format:

* The following keys are equivalent to the fields that appear in the text of
  the acquired events:
  * Category, CategoryString, ComputerName, EventCode, EventType, Keywords,
    LogName, Message, OpCode, RecordNumber, Sid, SidType, SourceName,
    TaskCategory, Type, User
* There are three special keys that do not appear literally in the event.
  * $TimeGenerated: The time that the computer generated the event
  * $Timestamp: The time that the event was received and recorded by the
                Event Log service.
  * $XmlRegex: Use this key for filtering when you render Windows Event
    log events in XML by setting the 'renderXml' setting to "true". Search
    the Splunk platform Getting Data In Manual for "Filter data in XML format 
    with the XmlRegex key" for details.
* The 'EventType' key is only available on Windows Server 2003 /
  Windows XP and earlier.

  "Monitor Windows Event Log Data" topic in the online documentation.

suppress_text = <boolean>
* Whether or not to include the description of the event text for a
  given Event Log event.
* This setting is optional.
* Set this setting to true to suppress the inclusion of the event
  text description.
* Set this value to false to include the event text description.
* Default: false

renderXml = <boolean>
* Whether or not the input returns the event data in XML (eXtensible Markup
  Language) format or in plain text.
* A value of "true" means that the input renders events in XML format.
* A value of "false" means that the input renders events in plain text.
* If you give this setting a value of "true", you should also give the
  'suppress_text', 'suppress_sourcename', 'suppress_keywords', 'suppress_task', and
  'suppress_opcode' settings a value of "true" to improve thruput performance.
* A value of "true" also changes the method by which you create allow-
  and deny lists to filter events. For these kinds of lists to work, you
  must use the '$xmlRegex' special key and assign regular expression values
  to use those lists. 
* Search the Splunk platform Getting Data In Manual for "Filter data in XML format
  with the XmlRegex Key" for details.
* Default: false

[admon://<name>]

* This section explains possible settings for configuring the Active Directory
  monitor input.
* Each admon:// stanza represents an individually configured Active
  Directory monitoring input. If you configure the input with Splunk Web,
  then the value of "<NAME>" matches what was specified there. While

  to use Splunk Web to configure Active Directory monitor
  inputs because it is easy to mistype the values for Active Directory
  monitor objects.

targetDc = <string>
* The fully qualified domain name of a valid, network-accessible
  Active Directory domain controller (DC).
* This setting is case sensitive. Do not use 'targetdc' or 'targetDC',

  Monitor input.
* Each WinRegMon:// stanza represents an individually configured
  WinRegMon monitoring input.
* If you configure the inputs with Splunk Web, the value of "<NAME>" matches
  what was specified there. While you can add event log monitor inputs

  the specified hive when it starts for the first time. It then
  monitors live events.
* Default: 0 (do not capture a baseline for the specified hive
  first before monitoring live events)

baseline_interval = <integer>
* Selects how much downtime in continuous registry monitoring should trigger
  a new baseline for the monitored hive and/or key.
* In detail:
  * Sets the minimum time interval, in seconds, between baselines.
  * At startup, a WinRegMon input does not generate a baseline if less time
    has passed since the last checkpoint than baseline_interval chooses.
  * In normal operation, checkpoints are updated frequently as data is
    acquired, so this will cause baselines to occur only when monitoring was
    not operating for a period of time.
* If baseline is set to 0 (disabled), the setting has no effect.
* Default: 86400 (1 day)

disabled = <boolean>
* Whether or not the input is enabled.

* The authentication region to use for signing requests when interacting
  with the Amazon Security Lake storage system that supports the Amazon S3 API.
* Used with v4 signatures only.
* The instance automatically constructs the Amazon S3 endpoint based on the
  bucket name and region specified in the SQS message (for example,
  https://<bucketname>.s3-us-west-1.amazonaws.com). When the SQS message does
  not provide a 'kms.auth_region', the instance attempts to extract the value
  from the Amazon s3 endpoint URL ("us-west-1" in the given example) for KMS
  authentication.
* If this setting is not set and the instance cannot determine an
  authentication region, the instance signs the request with an empty region
  value. This can lead to rejected requests when non-AWS S3-compatible storage
  is used.
* Optional.
* No default.

remote_queue.sqs_datalake.large_message_store.kms.key_id = <string>
* Currently not supported. This setting is related to a feature that is
  still under development.
* Specifies the identifier for KMS. The identifier is one of the following two
  things:

* This setting applies only for modular inputs. It takes effect only if you
  specify it under a default stanza of a modular input scheme.
* A default stanza of a modular input scheme begins with the notation
  [<scheme name>]
* If set to "true", Splunk software runs introspection on a modular input
  scheme even when you have disabled all the input scripts for the scheme.
* If set to "false", Splunk software does not run introspection on a modular
  input scheme where you have disabled all scripts for the scheme.
* If introspection does not run for a scheme, then Splunk software does not
  register the modular input scripts that are associated with the scheme
  for execution and it is disabled completely.
* Use the 'disabled' setting to enable or disable individual modular input scripts.
* For example, to turn introspection off for the modular input scheme "myScheme":

* This is the systemd-journald input component for Splunk

journalctl-include-fields = <string>
* This setting and the "journalctl-exclude-fields" setting control the fields
  that the journald input retrieves. 
* The input selects most of the fields if they are in 
  "one of "journalctl-include-fields" and not in 'journalctl-exclude-fields'.
* The exceptions are MESSAGE, CURSOR, and _REALTIME_TIMESTAMP. The system 
  treats these fields specially.
