Description
We have several IO time alerts for OSD itself:
- https://stats.openqa-monitor.qa.suse.de/d/WebuiDb/webui-summary?panelId=46&fullscreen&edit&tab=alert
- https://stats.openqa-monitor.qa.suse.de/d/WebuiDb/webui-summary?panelId=47&fullscreen&edit&tab=alert
- https://stats.openqa-monitor.qa.suse.de/d/WebuiDb/webui-summary?panelId=48&fullscreen&edit&tab=alert
- https://stats.openqa-monitor.qa.suse.de/d/WebuiDb/webui-summary?panelId=57&fullscreen&edit&tab=alert
They need to be reworked so that:
- The right disk is shown for the right purpose (e.g. /dev/vde is not /results any longer)
- https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/master/openqa/telegraf-webui.conf#L32 might needs adjustments to store persistent identifier like UUIDs
- The panel itself maybe can be generated out of info from salt (mountpoint): https://gitlab.suse.de/openqa/salt-states-openqa/-/blob/master/openqa/monitoring/grafana/webui.dashboard.json#L5769
- DONE:
The alert thresholds need to be adjusted to not trigger that oftenSpikes of up to 7s seem to happen from time to timeThe situation gets critical if these spikes continue for several minutes
All above linked alerts are on pause right now since they don't provide a big benefit being that flaky.

From what I learned in #73165 I can update current monitoring and alerting in https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/375 . I merged but it seems this did not trigger a CI pipeline in master anymore. Did that manually now.

Crossed of the point I have done. The rest is left to be done.

hm, given that the current state is ok again and we change the partition layout that seldomly I think it is ok like it is. Of course if someone has a cool idea we can rework our salt code, I have recorded that now in #65271
