How can I get access to metrics like CPU/memory at the node level?

Question

How can a customer get access to metrics like CPU/memory at the node level to take action to scale, debug issues, etc.? I cannot seem to run kubectl top on an ARO cluster.

You can access the CPU/Memory metrics at the node level by using the command oc adm top nodes or kubectl top nodes with the customer-admin cluster role. You can also access the CPU/Memory metrics of pods with the command oc adm top pods or kubectl top pods.
