An Ansible Role that installs MetricBeat on Red Hat/CentOS or Debian/Ubuntu.

Special thanks to Emiliano Castagnari (https://github.com/torian) for his Filebeat role. This role is based on the code of https://github.com/torian/ansible-role-filebeat

• EL / Centos (6 / 7)
• Debian (Wheezy / Jessie)
• Ubuntu (Trusty)

Available variables are listed below, along with their default values as definied in defaults/main.yml.

MetricBeat user and group. If you run MetricBeat with a user other than root make sure your logs are readable by the MetricBeat user. Add the MetricBeat user to a privileged group, with access to your logs.

On Ubuntu you would add the user to the adm group. On CentOS you can adjust the permissions with the setfacl command, e.g. sudo setfacl -m g:metricbeat:r <path>.

metricbeat_user: root
metricbeat_group: root

Create the metricbeat user and group.

metricbeat_create_user: true

MetricBeat version to use.

metricbeat_version: 5.0.0-alpha4

Make use of the MetricBeat repo (yum or apt).

You may use a URL to install a specific .deb or .rpm. To do so, change metricbeat_use_repo value to false, then (optionally) adjust the value of metricbeat_baseurl (which has a default value set for you).

metricbeat_use_repo: true

MetricBeat base URL for package download if metricbeat_use_repo: false

metricbeat_baseurl: "https://download.elastic.co/beats/metricbeat"

Start MetricBeat at boot time.

metricbeat_start_at_boot: true

MetricBeat version upgrade. This option allows package upgrades.

metricbeat_upgrade: false

MetricBeat configuration file.

metricbeat_config_file: /etc/metricbeat/metricbeat.yml

The MetricBeat configuration is built based on the variable metricbeat_config. For easier management of the contents, the metricbeat_config variable is made up of multiple other variables:

• metricbeat_config_modules
• metricbeat_config_general
• metricbeat_config_processors
• metricbeat_config_output
• metricbeat_config_logging
