Openshift probe - how to detect pod restarts

[Glenn Weavind]

We've suffered a number of apmservices-nass pod restarts which have caused other issues.  Support rapidly identified the CoreOS usage of Transparent Huge Pages (affects k8s and Openshift implementations) which resolved the pod crashes.

Is anyone able to tell me if I can use the UIM OpenShift probe to detect pods restarting/crashing (ideally within a given namespace) - and if so, how, please?

Hi Glenn, it seems that is perfectly possible:
https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/ca-unified-infrastructure-management-probes/GA/monitoring/clouds-containers-and-virtualization/openshift-monitoring/openshift-metrics.html#concept.dita_d3303fde-e786-4fd4-b0b6-e3a28fd60a82_pod

Just monitor the metric "Total Restarts" from the apmservices-nass pod.
