[systemd-devel] monitoring systemd unit flapping

[Jeremy Eder]

Sorry, I did not explain myself clearly.  systemd is doing nothing wrong.
What I'd like to do is find an optimal way to notify our monitoring system
(zabbix) that a service is flapping.  We can probably script something.
Just looking to see if there's a more elegant way.  Looking also at
OnFailure

https://serverfault.com/questions/694818/get-notification-when-systemd-monitored-service-enters-failed-state

At the same time, trying to avoid false positives in the monitoring system,
so one failure is OK but when it hits startburstlimit, things are bad, even
if the service doesn't immediately crash.  That's the thing; it might take
a few seconds/minutes to fail.  I realize this could be considered an edge
case...perhaps an equivalent of OnFailure could be OnStartBurstLimit= ?
