Description

Observation

Since early morning the download rate for this worker dropped to zero: https://stats.openqa-monitor.qa.suse.de/d/WDopenqaworker2/worker-dashboard-openqaworker2?tab=alert&viewPanel=65109&orgId=1&from=1651366172156&to=1651391164493

The time frame correlates with the problem on openqaworker5 mentioned in #110494; side note: both servers are in the same rack.

Initial investigation shows massive problems with the networking in the mentioned time-frame and then a reboot with more networking issues

Suggestions

  • Try to find openQA jobs according to the time frame where a zero or low bandwidth was recorded
  • The above errors are all within the timeframe where we do a full upgrade and reboot of workers as well as webUI host so maybe we have false positive alerting.
  • Likely the openQA minion influxdb route actually reports a download speed of true zero if the minion was restarted (e.g. after reboot and system startup) and either no openQA jobs had been running at all or only already cached assets would been used -> Research how the code behaves after minion startup and only using cached assets.
  • Avoid the reporting of zero if there is no actual download going on (grafana is already configured to keep the last state if there are no new values)
