Hi Thank you for your reply.
I tried this querry in alerts as well as as in prometheus dashboard alerts
9090.
There is no alert fired even though i changed
max_over_time(probe_success{job="abc"}[5m]) == 0
other alerts like slow probes etc are firing. I am not sure this the
correct querry i have used. there are instances which are down for more
24hrs. so in my case i should have a alert fired.
Does the alert will wait till 24hrs and then fired?
