| Doc Text: |
Cause: the AlertmanagerConfigInconsistent alert could fire during an upgrade because some of the Alertmanager pods were temporarily not running due to a rolling update of the statefulset. The alert resolved itself once all Alertmanager pods had been updated.
Consequence: the firing alert generated noise that was confusing for the cluster admins, especially because there wasn't any inconsistency in the configuration.
Fix: the AlertmanagerConfigInconsistent alert has been fixed to not consider the number of running Alertmanager pods.
Result: the AlertmanagerConfigInconsistent alert doesn't fire anymore during upgrades when some of the Alertmanager pods are in a not-running transient state.
