given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for

Description

The metricbeat installs the metricbeat operating system and service collector maintained by elastic.

Setup

What metricbeat affects

By default metricbeat adds a software repository to your system and installs metricbeat along with required configurations.

Beginning with metricbeat

Full metricbeat functionality cam be configured with the modules and outputs parameters declared. This module can run but the metricbeat agent on the nodes may not start their services without these parameters defined.

class{'metricbeat':
  modules => [
    {
      'module'     => 'system',
      'metricsets' => [
        'cpu',
        'load',
        'memory',
        'process',
      ],
      'processes'  => ['.*'],
    },
  ],
  outputs => {
    'elasticsearch' => {
      'hosts' => ['http://localhost:9200'],
      'index' => 'metricbeat',
    },
  },
}

Usage

As of this writing all the default values follow the upstream values. This module saves all configuration options in a to_yaml() fashion. Therefore this allows some advanced configuration settings to be easily rendered.

To ship metrics from an Apache Web Server to Elasticsearch

class{'metricbeat':
  modules => [
    {
      'module'     => 'apache',
      'metricsets' => ['status'],
      'hosts'      => ['http://localhost'],
    },
  ],
  outputs => {
    'elasticsearch' => {
      'hosts' => ['http://localhost:9200'],
    },
  },
}

To ship metrics from a MySQL Database Server to Logstash

class{'metricbeat':
  modules => {
    'module' => 'mysql',
    'metricsets' => ['status'],
    'hosts'      => ['tcp(127.0.0.1:3306)/']
    'username'   => 'root',
    'password'   => 'secret',
  },
  outputs => {
    'logstash' => {
      'hosts' => ['localhost:5044'],
    },
  },
}

To use the module via Hiera:

metricbeat::major_version: '6'
metricbeat::manage_repo: true
metricbeat::package_ensure: 'latest'
metricbeat::cloud_id: 'xxx'
metricbeat::cloud_auth: 'xxx:xxx'
metricbeat::fields_under_root: true
metricbeat::fields:
  'metricbeat.config.modules':
    'path': '${path.config}/modules.d/*.yml'
    'reload.enabled': false
  'setup.dashboards.enabled': true
  'setup.template.settings':
    'index.number_of_shards': 1
    'index.codec': 'best_compression'
metricbeat::outputs:
  'elasticsearch':
    'hosts': 'localhost:9200'
metricbeat::xpack:
  'monitoring':
    'enabled': true
metricbeat::module_templates:
  - system

Please review the elastic documentation for configuration options and service compatability.

Upgrade to 6.0

Version 0.2.0 of this module supports Metricbeat 6.0. Please review the Metricbeat Changelog for a full list of software changes and the module changelog for a list of module updates.

To upgrade existing installations:

class{'metricbeat':
  'major_version'  => '6',
  'package_ensure' => 'latest',
  ...
}

Processors

Libbeat 5.0 and later include a feature for filtering/enhancing exported data called processors. These may be added into the configuration by populating the processors parameter and may apply to all events or those that match certain conditions.

To drop events when field apache.status.total_accesses is 0

class{'metricbeat':
  processors => [
    {
      'drop_event' => {
        'when' => {
          'apache.status.total_accesses' => 0,
        }
      }
    }
  ],
  ...
}

To drop the mysql.status.aborted.clients field from the output

class{'metricbeat':
  processors => [
    {
      'drop_field' => {
        'fields' => 'mysql.status.aborted.clients',
      }
    }
  ]
}

Please review the documentation
