Pod metrics not shown

[manju-rn]

The node metrics are show. However the pod metrics are not shown. Can headlamp display that? the cpu and memory usage along with requests and limits information would greatly help

Here is my output of k top pods -A

Hi! As I know for pod metrics to work you should have prometheus installed inside your k8s cluster

Is this a headlamp requirement? Since pod metrics generally works fine without it as per my snapshot in earlier post above

Yes, headlamp use prometheus plugin for rendering metrics, it search for a prometheus instance inside of the k8s cluster and grab metrics from it.

Hi @manju-rn you can try installing prometheus in Headlamp app by selecting the Apps page from the sidebar. Please check prometheus plugins for more information.
