[28372] False-positive liveness probe failures for ‘fluentd-notifications’

Fixed in 23.1

If a cluster does not currently have any ongoing operations that comprise OpenStack notifications, the fluentd containers in the fluentd-notifications Pods are frequently restarted due to false-positive failures of liveness probe and trigger alerts.

Ignore such failures and alerts if the Pods are in the Running state. To verify the fluentd-notifications Pods:

kubectl get po -n stacklight -l app=fluentd

Example of system response:
