• xymon_cli__pkg_list : The list of packages to install to provide xymon-client.
• xymon_cli__plug_pkg_list : The list of packages to install to provide extra plugins to Xymon client.

Example Playbook

• Use defaults vars :

- hosts: serverXYZ
  roles:
    - role: ipr-cnrs.xymon

Configuration

This role will :

• Install needed packages to provide xymon-client.
• Manage xymon-client configuration and service.
• Add 'xymon' user to new groups.

Plugins

Some plugins and options can be managed with this role :

• apt : Check state of packages and repositories.
• kern : Check for outdated running kernel and need for reboot.
• libs : Check for running processes with upgraded libraries.
• mq : Check mail queue.
• zfs : Check ZFS pools status.

Development

This source code comes from our Gogs instance and the Github repo exist just to be able to send the role to Ansible Galaxy…

But feel free to send issue/PR here :)

Thanks to this hook, Github automatically got updates from our Gogs instance :)
