Suggestions¶
Follow https://progress.opensuse.org/projects/qa/wiki/Tools#Process
Look at https://stats.openqa-monitor.qa.suse.de/d/WDopenqaworker3/worker-dashboard-openqaworker3?editPanel=65109&tab=alert&orgId=1
Maybe the webUI was affected since workers 2,3,8,9 were impacted
- Looks like it was only individual jobs on each worker conducting download, maybe again just zypper and mirror infrastructure problems, see https://progress.opensuse.org/issues/112232 -> Ask where the monitoring for the mirroring infrastructure is. Most likely there is none so it's again openQA tests that do the monitoring \o/ -> can't be because this is about asset download
- likely only single jobs where downloading something, others could relate to cache, so check for the corresponding time what happened on osd
- Create separate ticket to handle the job age ticket better so that individual jobs stuck in the queue when the schedule is otherwise empty will not trigger alerts
- Check which jobs were running on the workers, e.g.:
select id, t_started, t_finished, result, reason from jobs where (select host from workers where id = assigned_worker_id) = 'openqaworker9' and t_started >= '2022-06-12T16:44:00' and t_started < '2022-06-12T22:48:00' order by t_finished;
