Hello,
I'm having some trouble writing a query for an alerting rule that we only
want to run at certain times of the day. This is what I original had, which
works, but not in the way we now need:
> count(up{job="calculator"} == 0) and count(hour(vector(time())) >= 1 and
hour(vector(time())) < 13)
Now our problem is that we need the instance label from the up metric to
persist to the alert so we can include it in the pager duty incident,
otherwise our engineers don't know what instance is down without checking
prometheus first. This is where I'm having problems, using count strips all
those labels and just basically gives a true or false of if the alert is
firing.
Any suggestions?
