CPU and Memory current Usage per deployment is missing

[doronshai]

What problem are you trying to solve? Do you a suggestion on how to solve it?

When using workloads > deployment view, there are columns about CPU and Memory Usage which are empty. This is an important metrics that need to be presented

[goenning]

Hey @doronshai we use Kubernetes Metrics API to populate that column, so your cluster needs to host a compatible implementation.

The most popular ones are metrics-server and prometheus-adapter (if you’re already using Prometheus)

@goenning I installed the prometheus-adapter and enabled the external metrics, but no usage for node, deployment or pod is showing up.

Does kubectl top nodes or kubectl top pods return anything?

no, error: Metrics API not available. I don't know what to do next.

Ok, i made it work. The resource metrics must be enabled in prometheus adapter.
