How to troubleshoot and find out which process is causing high CPU on containers.

Please help on this, as there no pids associated in containers nothing is available to check which process is running with high CPU consumption.

    Hello Sai!

    You may want to use kubectl exec command to connect to your pods (for example, if bash is installed "kubectl exec -it <podname> -n <namespace> -- bash") and run the following command to sort the PIDs and PPIDs based on highest CPU consumption:

    ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%cpu | head

    I hope this is helpful. If any clarification needed, let me know and I will do my best to answer.
