Hi,
I have alertmanager cluster setup with 12 nodes set up in a cluster mode
with consistent 12 cluster members.
I am getting multiple alerts firing for some alerts. Looking at counts of
changes(ALERTS_FOR_STATE)
on these alerts is way less than actual events firing out of alertmanager.
I am storing events fired in a database with timestamps.
The fingerprint counts on these alerts is way more than state change as
shared in the dashboard.
I am using following expression in the alerting rule:
(sum(last_over_time(..{}[2h]) / last_over_time(...) * 100) > 90
Any pointers to debug this issue is highly appreciated!
