Puppet Class: splunk

Inherits:
splunk::params
Defined in:
manifests/init.pp

Overview

Class: splunk

The splunk module will install Splunk agents in the form of a Light Weight Fowarder, Heavy Forwarder, Universal Forwarder. It will also install servers for index, job and search configurations.

Please Note: This Module assumes you have the Splunk Packages in some sort of package repo.

Parameters

Document parameters here.

index

Default index to sent inputs to. Defaults to ‘os’

localusers
licenseserver

fqdn of License host, passing this param will turn the node into a license slave of a configured license server. For a license master set licenseserver => ‘self’

nagios_contacts

Accepts a comma seperated list of contacts. Then enables and exports Nagios Service checks for monitoring.

output_hash

Optional hash of outputs that can be used instead of, or in addition to the default group (tcpout) Useful for forwarding data to third party tools from indexers.

output_hash => { ‘syslog:example_group’ => {

    'server' => 'server.example.com:514' }
}
package_provider

Defaults to undef

package_source

Defaults to undef

port

Splunk Default Input Port for indexers. Defaults to 9997. This sets both The ports Monitored and the ports set in outputs.conf

proxyserver

Define a proxy server for Splunk to use. Defaults to false.

purge

purge => true purge defaults to false, and only accepts a boolean as an argument. purge purges all traces of splunk without a backup.

splunkadmin
target_group

Hash used to define splunk default groups and servers, valid configs are { ‘target group name’ => ‘server/ip’ }

type

Install type. Defaults to Universal Forwarder valid inputs are: uf : Splunk Universal Forwarder lwf : Splunk Light Weight Forwarder hwf : Splunk Heavy Weight Forwarder jobs : Splunk Jobs Server - Search + Forwarding search : Splunk Search Head indexer : Splunk Distribuited Index Server

version

Install package version, defaults to ‘latest’

Variables

Here you should define a list of variables that this module would require.

sample_variable

Explanation of how this variable affects the funtion of this class and if it has a default. e.g. “The parameter enc_ntp_servers must be set by the External Node Classifier as a comma separated list of hostnames.” (Note, global variables should not be used in preference to class parameters as of Puppet 2.6.)

Examples

class { splunk:
  type => 'lwf',
}
