Is is unsual or should I do something about this?

I was diagnosing why grafana wasn't working and was about to get the pod name to check the logs

CodePudding user response：

These are completed jobs. If you don't want to see so many of them, then you will have to configure job history limits; specifically .spec.successfulJobsHistoryLimit and .spec.failedJobsHistoryLimit in the grafana Job spec.
