Question about "monitor cluster component"

hlngai · September 1, 2020, 9:37am

Hi,

I downloaded the metric server using the link in the lab, and I encountered the following error when I run “kubectl top nodes”

Sometimes, I can get the resource usage status, but I got this error sometimes

How can I solve this?

Thank you.

Hello, @hlngai
It takes time to collect metrics from the cluster. Is it after a few min ?

Hi,

For the lab, I can get the resource usage after several min.

But for my testing environment, sometime I can get the resource usage, but sometimes I get this error

Might be a authentication or permission issue is the reason of fails. What about logs of metrics pods?

That’s quite weird, I try to get the log by the following command:
kubectl logs pod/metrics-server-xxxxx -n kube-system
