Description

Observation

  • Alerts Disk I/O time for /dev/vdd (/results) handled in #96554
  • Alerts for Job age (scheduled)
  • Alerts for Failed systemd services
    • This is about the alert from 02.08.21 01:17 (the one from 05.08.21 07:26 was caused by a user's misconfiguration).

Suggestion

  • Bump our thresholds
  • Investigate if our average load has increased immensely e.g. new test groups being scheduled
  • Look at systemd journal while the alert is running (short of having #96551)
  • Check if we have data on reduced heat/ power in server room 2
  • Job age (scheduled) (median) is likely due to issues with the WORKER_CLASS of https://openqa.suse.de/tests/6513484

Not sure how workable this ticket is. There's only one point left of the ones mentioned under observation and retrospectively it is hard to tell what was wrong at the time and we handled future alerts of the same kind. I get that this is an epic but the ticket title and description don't relate with the remaining sub tasks in a meaningful way.
