Description

This module can be used to install and configure the Graylog Collector Sidecar. (http://docs.graylog.org/en/2.2/pages/collector_sidecar.html)

Setup

Since this module has not been published to puppetforge yet, include its git repository in your Puppetfile:

mod 'gcs',
    git: 'https://github.com/tentwentyfour/puppet-graylog-collector-sidecar.git',
    ref: '0.4.2'

Setup requirements

The module requires puppetlabs-stdlib, puppet-remote_file and puppetlabs-apt on Debian-based OSs.

What graylog-collector-sidecar affects

The graylog-collector-sidecar module manages the following things:

  • Graylog-collector-sidecar packages
  • Graylog-collector-sidecar configuration file
  • Graylog-collector-sidecar service

Usage

You can configure the module using hiera:

include ::gcs

gcs::server_url: http://my.graylog.server:9000/api
gcs::update_interval: 15
gcs::tags:
  - linux
  - icinga2
  - nginx

The same can be achieved using puppet manifests only:

class { '::gcs':
    update_interval => 10,
    server_url      => 'http://my.graylog.server:9000/api',
    tags            => [
       'linux',
       'icinga2',
       'nginx',
    ],
}

  • Start collector-sidecar and enable the service

This class requires that you set the server_url parameter. All other parameters are optional.
