So after talking to Nick yesterday, seems that we're dropping collectd, however I already had something, so I polished "a bit" and created a repo in my personal github account. The exersice was fun though.

Currently it will only report the output of systemctl is-active openqa-worker@$instance, the number of worker instances is configurable via collectd plugin, what is missing:

  • Reporting last job that the worker ran
  • Check whether the openqa-worker service is actually running (Would need something like a worker heartbeat, or perhaps some other fancy thing that allows querying the information)
  • Register proper datatypes that match better what systemd reports on a first level, also to report information from jobs, and statistics from them.

The plugin is here: https://github.com/foursixnine/Collectd-Plugins-openQA

While the documentation should be enough, I'm leaving here what I used to set it up:

<Plugin perl>
        IncludeDir "/home/foursixnine/Projects/foursixnine.io/openqa-collectd/lib"
        BaseName "Collectd::Plugins"
        LoadPlugin openQA

        <Plugin openQA>
                worker_instances 10
        </Plugin>
</Plugin>

The output looks like this: 

[2018-10-25 01:51:49] Dispatching: systemctl is-active --quiet openqa-worker@7                                                                                                                                     
 {                                                                                                                                                                                                                 
  plugin => "openQA-worker",                                                                                                                                                                                       
  type => "gauge",                                                                                                                                                                                                 
  type_instance => "systemd_service_7",                                                                                                                                                                            
  values => [3],                                                                                                                                                                                                   
}

I'm also attaching an example file.
