ansible-role-collectd

Configures a collectd with a few roles

Requirements

/etc/collectd.d/ directory

Role Variables

Example for how to add more plugins and how to configure them when using the apache encoder style.

Want to configure collectd to ship metrics with the collectd protocol with a username/password and set graphite prefix? Set this:

collectd_tsdb_writer: False
collectd_network_server: True

# There is another prefix example in defaults/main.yml
collectd_prefix_rules:
  - name: generic_prefix
    regexp: "^hpc\\.clustername\\."
    invert_match: True
    prefix: "hpc.clustername."
    stop: False

collectd_plugins_processes: ""
collectd_plugins_network:
  - options:
    - LoadPlugin: network
  - sections:
    - name: Plugin
      param: network
      content:
        - options:
          - Forward: True
        - sections:
          - name: Server
            param: "{{ collectd_network_server_host }}"
            content:
              - options:
                - SecurityLevel: Encrypt
                - Username: "{{ collectd_username }}"
                - Password: "{{ collectd_password }}"
#
collectd_plugins_custom: "{{
  collectd_plugins_aggregation +
  collectd_plugins_cpufreq +
  collectd_plugins_exec +
  collectd_plugins_network
}}"

External IPMI scripts

This role fetches a few scripts from other github repos for IPMI statistics. If you set "collectd_force_geturl: True" then this role will re-download those scripts if they already exists.

With collectd_drop_rsyslog_spam True we install an rsyslog.d/ file that drops "value has been dispatche d" syslog messages from the exec plugin.

Dependencies

Some ideas borrowed from https://github.com/picotrading/ansible-collectd and that role uses the apache_encoder_macro.j2 from picotrading -

https://raw.githubusercontent.com/picotrading/config-encoder-macros/master/macros/apache_encode_macro.j2

ansible 2.0 (because checksum= with get_url: module)

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
     - { role: ansible-role-collectd }

Known Issues / Caveats

version v2.0.0 of this role will fail if variable collectd_set_graphite_prefix is defined. Github issues #10 and #12
