OpenShift best practices: what metrics and parameters to monitor

Hi,

Need information regarding what is best to monitor (what metrics, parameters, etc.) on the OpenShift side using Dynatrace? Do you have a list of such metrics from your experience?

Hi @radek_jasinski,

Maybe you should check @florian_g post:

dynatrace-api/metric-expressions-for-k8s.md at master · Dynatrace/dynatrace-api · GitHub

For my clinets the most important metrics are: number of conatiner restarts, oom kills, cpu throttling, pod phases (failed and pending):

Kubernetes events numberes:

Node status information:

And based on Florian post the resourse request and limits information. Where can we should reduce or increase the requests and limits (quite basic, manual solution... ), you can find the metric expressions in Florain's post:

I hope it helps.

Best regards,

Mizső
