If you know a specific value of contextCSN that you're looking for, then
you can put it in a label, and your alerting expression can check for
the absence of a timeseries:
expr: absent(foo{instance="bar",contextCSN="abcd1234"})
OpenLDAP's contextCSN values change a lot for each write operation to
one of the provider replicas. From my understanding putting these values
in labels would create a new time-series all the time you write to your
OpenLDAP servers.
Or maybe I did not really get your idea.
