action #167728
closedcoordination #161414: [epic] Improved salt based infrastructure management
grafana dashboard for monitor.qe.nue2.suse.org size:S
0%
Description
Motivation¶
In #167719 we ran out of space because influxdb grew to 300G+ on monitor.qe.nue2.suse.org and okurz only realized because grafana did not show any more up-to-date data. There was no related alert and also no alert about the decreased availability of space on the host before the incident. We have telegraf running on monitor but we have no generic machine dashboard which we should have like for other "generic" machines, i.e. not-worker and not-webui.
Acceptance criteria¶
- AC1: A machine specific grafana dashboard with alert definitions exists for all machines (including monitor.qe.nue2.suse.org)
- AC2: Special machine roles like openQA worker and openQA webUI don't have multiple dashboards showing the same data (e.g. not special openQA one + generic one)
Suggestions¶
- In https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/ac3057d7835f7ab842c9c3a508417f87e7ab6d55/monitoring/grafana.sls#L8 we set "genericnames" to all machines which are not worker, not webui and not monitor. That means we don't create a generic machine monitoring for monitor. Review where "genericnames" is used and evaluate if that can be tweaked to still create a generic machine monitoring dashboard for monitor while not applying other potentially harmful changes to the host

Need some inputs:
- How to setup a local instance for testing changes?
- How to perform changes on monitor.qa.suse.de without downtime?

You can try to run make test but in most cases it's fine to trust the automatic CI tests when you create a merge request. An alternative would be to spawn containers or VMs manually and try out changes in there but that's likely not very efficient for this issue and too much effort with no guarantee to see all side-effects. Another alternative is to manually change the salt repository on the salt master openqa.suse.de, apply the changes by applying a high state but only for monitor.qe.nue2.suse.org and check for the effect.

That is handled by the automatic CI pipelines so after you create a merge request in https://gitlab.suse.de/openqa/salt-states-openqa tests are running and after the MR is merged the changes are automatically deployed without downtime.

Haven't tried any changes yet, just tried executing make test and getting below error:
