Check command 'systemd_service' does not exist

Icinga 2
#1

Hello!

I am new to Icinga2 and have a problem configuring a custom plugin/check command.

I downloaded and added the check_systemd_service file and added it on my master to /usr/lib/nagios/plugins. Then i configured the command in Icingaweb2.
The problem now is, that this file is not deployed from the master to the agents, so i get “Check command ‘systemd_service’ does not exist.” as check result.
On one agent i manually added the check_systemd_service file manually to the same path like on the master and the check works fine now. But i expectet, that the file ist distributed automatically to the agents.

Would be great if someone could help me to get this working oder if someone could tell me what would be the best practice to deploy command files automatically.

Thanks in advance!

Hi & welcome,

this is not a job for icinga but for devops candidates e.g. Ansible, Chef, Puppet, Saltstack etc.

BTW: For better readability we always love to see posts formatted according to this guideline.

The CheckCommand can be distributed via Icinga2 (depending on Zone, configurations), but the plugin script itself needs to be deployed by some other means as @rsx stated.

Your error seems to indicate the CheckCommand was missing, as opposed to execvpe (...) failed: No such file or directory which indicates the plugin script defined by the CheckCommand is inaccessible.

You may also want to consider using PluginContribDir (defined in constants.conf) as a prefix and syncing that directory across your hosts by some other means (rpm, config management, etc).

Thank you both for your replies!

I already suspected that I would have to distribute the plugin files with ansible or something similar. But I wasn’t sure and wanted to rule out that I had done something wrong with the configuration.

Is there already a playbook for ansible that you can recommend for the task?

Many thanks for your help!
