Ansible Role: Beats

Test Role Beats

This role installs and configures Beats. You can use it as a standalone role or combine it with our other roles managing the Elastic Stack.

Requirements

You need to have the beats you want to install available in your software repositories. We provide a role for just that but if you have other ways of managing software, just make sure it's available. Alternatively you can install the Beats yourself.

  • community.crypto collection: ansible-galaxy collection install community.crypto

Role Variables

  • beats_filebeat: Install and manage filebeat (Default: true)
  • beats_filebeat_enable: Automatically start Filebeat (Default: true)
  • beats_filebeat_output: Set to logstash or elasticsearch. (default: logstash)
  • beats_filebeat_elastic_monitoring: filebeat monitoring over Elastic Stack monitoring features (default: false)
  • beats_filebeat_syslog_udp: Use UDP Syslog input (Default: false)
  • beats_filebeat_syslog_udp_port: Port of UDP Syslog input (Default: 514)
  • beats_filebeat_syslog_tcp: Use TCP Syslog input (Default: false)
  • beats_filebeat_syslog_tcp_port: Port of TCP Syslog input (Default: 514)
  • beats_filebeat_log_input: Enable Logfile reading (Default: true)
  • beats_filebeat_mysql_slowlog_input: Enable MySQL/MariaDB slow query log collection incl. multiline (Default: false)
  • beats_filebeat_log_inputs: Logfiles to read (Default: see below)

Default of beats_filebeat_log_inputs

  messages:
    name: messages
    paths:
      - /var/log/messages

You can optionally add fields to every input as well. You can also add a multiline section with options (type, pattern, negate and match so far)

Here's a longer example for an input:

beats_filebeat_log_inputs:
  messages:
    name: messages
    paths:
      - /var/log/messages
      - /var/log/secure
      - /var/log/httpd/*access_log*
    multiline:

      pattern: '^[[:space:]]+(at|\.{3})[[:space:]]+\b|^Caused by:'
      negate: false
      match: after
  • beats_filebeat_journald: Enable collection of JournalD logs (default: false) - available since Filebeat 7.16
  • beats_filebeat_journald_inputs: List of journald inputs. Use for different filters on events. You can add a list of include_matches entries for filtering. Default of beats_filebeat_journald_inputs:
beats_filebeat_journald_inputs:
