Using Rancher Alerts to monitor for cattle-system pods that restart frequently?

1

Hi folks,

We’d like to use the Rancher Alert system to monitor for specific Rancher Pods that we’ve had problems with, such as cattle-cluster-agent & cattle-node-agent.

We would like to monitor for frequent restarts, or perhaps for the frequent occurrences of something like CrashLoopBackOff. I cannot figure out how to monitor individual pods using Rancher Alerts.

I have tried a few things such as kube_pod_container_status_restarts_total{namespace="cattle-system", pod=~"cattle-cluster-agent*}, as shown below but without success:

Can any one point in the correct direction?

Hi Stefan,
Have you got it working yet?
I have been trying to achieve the same thing.
