This is strange. I would expect your original definition to work as well,
since the alarm key in Vitrage is defined by a combination of the alert
name and the instance. We will check it again.
BTW, we solved a different bug related to Prometheus alarms not being
cleared [1]. Could it be related?

Does the wrong timestamp appear if you run 'vitrage alarm list' cli
command? please try running 'vitrage alarm list --debug' and send me the
output.

Please send me vitrage-collector.log and vitrage-graph.log from the time
that the problematic vm was created and deleted. Please also create and
delete a vm on your 'ubuntu' server, so I can check the differences in the
log.

Unfortunately, Vitrage does not hold pods and containers information at the
moment. We discussed the option of adding it in Stein release, but I'm not
sure we will get to do it.
