puppet-graylog_collector

Overview

Puppet module to manage Graylog Collector

You should refer to the Graylog Collector Documentation at http://docs.graylog.org/en/latest/pages/collector.html to aide you in the use of this module. Most parameters map to the configuration options.

Module Description

Manages the installation and configuration of Graylog Collector, including configuring inputs and outputs.

Setup

What graylog_collector affects

Installs the Graylog Collector via archive or package
Optionally manages package managment repos
Optionally manages the user/group to run as
Optionally provides an init script and optionally manages the service

The absolute path to the java executable to use for running the Graylog Collector.

java_opts

Default: undef

Any additional Java options to pass when running Graylog Collector.

user

Default: 'root'

The user to run Graylog Collector as. Keep in mind that the collector needs access to whatever files you feed to it.

group

Default: 'root'

The group for the collector. This is used for ownership of the config files.

manage_user

Default: false

Specifies whether this module should manage the user. If you're running as root, you probably shouldn't let this module manage the user.

manage_group

Default: false

Specifies whether this module should manage the group. If you're running as root, you probably shouldn't let this module manage the group.

manage_init

Default: undef

Specifies whether this module should manage the init script or init config file.

If install_from is set to package, this manage_init defaults to false

If installing from archive, it defaults to true

manage_service

Default: true

Specifies whether this module should manage the service.

service_ensure

Default: 'running'

State of the service.

service_enable

Default: true

Enable the service on boot or not.

service_name

Default: 'graylog-collector'

The name of the service to manage if manage_service is true.

install_from

Default: depends on platform

Possible values are package and archive

Defaults to package for:

Ubuntu 12x
Ubuntu 14x
Debian 8
EL 7

Defaults to archive for everything else.

Refer to the Graylog Collector documentation for information about package repositories.

version

Default: depends on installation method

For archive, it defaults to 0.4.1. For package, it defaults to installed

The version of Graylog Collector to install.

source_url

Default: 'https://packages.graylog2.org/releases/graylog-collector/graylog-collector-0.4.0.tgz'

This is not relevant if install_from is set to package

URL to download the tarball from for installation when install_from is set to 'archive'

service_file

Absolute path to the location of the init script or service definition.

service_template

Optional custom template to use for the service file/init script.

manage_repo

Whether this module should manage the package repositories. This is only relevant if installing via package.

Defined Type: `graylog_collector::input`

Refer to http://docs.graylog.org/en/latest/pages/collector.html#input-settings and http://docs.graylog.org/en/latest/pages/collector.html#input-output-routing

input_name

Default: $title

The name of the input to manage

path

Default: undef

If collecting an absolute path, this should refer to it.

type

Default: 'file'

path_glob_root

Default: undef

If you're collecting a file glob (e.g. *.log), this should refer to the base directory that contains that glob.

Example: '/usr/share/tomcat/logs'

path_glob_pattern

Default: undef

The glob pattern used for collection.

Example: '.log' or '.{err,log}'

content_splitter

Default: 'NEWLINE'

How to split the content. Basically - how to separate messages. Valid options are 'NEWLINE' or 'PATTERN'

content_splitter_pattern

Default: undef

If splitting on 'PATTERN', what regex should be used to separate log messages.

Note that regex escapes must be escaped. So a normal regex pattern of \d should be \\d

charset

Default: 'UTF-8'

reader_interval

Default: '100ms'

global_message_fields

Hash.

Default: {}

Message fields allow for you to add your own fields to a log message. For example, appending the application name or some other metadata. The 'global' message fields parameter is intended for situations where you'd like to apply a global set of fields to all inputs, but allow for application-specific fields to be added. Since these are hashes, you would normally need a wrapper or some other trickery to combine a global set of fields with application-specific fields, or declare your global fields with every declaration of an input. This is useful, for example, when you'd like to set message fields with something like Hiera or in a base profile.

The global message fields will be merged with the 'message_fields' parameter.

Example:

global_message_fields {
  'fqdn'            => $::fqdn,
  'org_environment' => $::org_environment,
}

message_fields

Hash.

Default: {}

Refer to 'global_message_fields' above. These are fields in addition to the 'global_message_fields'. These take precedence, however.

global_message_fields {
  'application_name' => 'tomcat',
  'app'              => 'pluto',
  'logfile'          => 'catalina.out',
}

outputs

Default: undef

Array.

The outputs to send this input to. See graylog::collector::output You can specify an output on the input or an input on the output (whoa).

Defined Type: `graylog_collector::output`

Refer to http://docs.graylog.org/en/latest/pages/collector.html#output-settings and http://docs.graylog.org/en/latest/pages/collector.html#input-output-routing

output_name

Default: title

The name of the output to configure. Example: 'gelf'

type

Default: gelf

The type of output. Valid options are 'gelf' and 'stdout'

host

Default: undef

If type is 'gelf', this refers to the host to send logs to. The Graylog2 server should have a GELF TCP input configured and listening.

port

Default: undef

If type is 'gelf', this refers to the port to send logs to. The Graylog2 server should have a GELF TCP input configured and listening.

client_tls

Boolean.

Default: false

Specifies whether to use TLS to connect when the output is 'gelf'

client_tls_cert_chain_file

Default: undef

client_tls_verify_cert

Boolean.

Default: true

client_queue_size

Default: '512'

client_connect_timeout

Default: '5000'

client_reconnect_delay

Default: '1000'

client_tcp_no_delay

Boolean.

Default: true

client_send_buffer_size

Default: '-1'

inputs

Array.

Default: undef

Works like 'outputs' with graylog_collector::input. What inputs should be sent to this output. You can leave this empty and specify them with the input if you'd like.

Examples

Example of declaring the common configuration in a base profile:

class profile::base::graylog {
  class { '::graylog_collector':
    server_url => '8.8.8.8:12900',
  }

  graylog_collector::output { 'gelf':
    type => 'gelf',
    host => '8.8.8.8',
    port => '12900',
  }
}

Example of managing an 'input' for a specific application:

class profile::apps::pluto {
  graylog_collector::input { 'pluto_catalina_out':
    path                     => "${catalina_base}/logs/catalina.out",
    content_splitter         => 'PATTERN',
    content_splitter_pattern => '^(\\d{4}-\\d{2}-\\d{2}|\\d{2}-\\w{3}-\\d{4})\\s\\d{1,2}:\\d{1,2}:\\d{1,2}',
    message_fields           => {
      'application_name' => 'tomcat',
      'app'              => 'pluto',
      'logfile'          => 'catalina.out',
    }
  }
}

Example of a file glob:

class profile::apps::pluto {
  graylog_collector::input { 'pluto_tomcat_logs':
    path_glob_root           => "${catalina_base}/logs",
    path_glob_pattern        => "*.{out,log,txt}",
    content_splitter         => 'PATTERN',
    content_splitter_pattern => '^(\\d{4}-\\d{2}-\\d{2}|\\d{2}-\\w{3}-\\d{4})\\s\\d{1,2}:\\d{1,2}:\\d{1,2}',
    message_fields           => {
      'application_name' => 'tomcat',
      'app'              => 'pluto',
    }
  }
}

An example of using a collector to add 'global_message_fields' to all inputs:

Graylog_collector::Input <| |> {
  outputs               => [ 'gelf' ],
  global_message_fields => {
    'fqdn'            => $::fqdn,
    'org_environment' => $::org_environment,
  }
}
