Node CPU Use in the Dashboard not working

[ragkota]

Hi,
I have used k8dash to create dashboard. Everything seems to work fine, except that Node CPU use and Node RAM use under Nodes tab is not working. Any ideas what could be missing?
Please see below relevant information. Thanks,
Raghu

I'm facing the same issue with cluster running with docker-desktop on windows.
If I go into the concrete node I see this:

Would you mind checking the networking tab in your browsers developer tools and see if there's any more info there that might help track down what's going on here?

I resolved this using below patch

kubernetes-sigs/metrics-server#143 for metrics-server

/apis/metrics.k8s.io/v1beta1/nodes/{node_name} or /apis/metrics.k8s.io/v1beta1/namespaces/docker/pods/{pod_name} return 404 not found.

But /apis/metrics.k8s.io/v1beta1/nodes or /apis/metrics.k8s.io/v1beta1/pods without specifying concrete resource are 200 OK.

Thanks for the update @ragkota

@dennismeissel Sounds like maybe you're experiencing the same issue?

It helped me also.
Thanks both of you!
