Kubernetes Dashboard does not show CPU and Memory Usage-CodePudding

I have a Problem with the Kubernetes Dashboard. I use actually the Managed Kubernetes Service AKS and created a Kubernetes Cluster with following Setup:

Kubernetes-Version 1.20.9
1 Worker Node with Size Standard_DS2_v2

It starts successfully with the automatic configuration of coredns, corednsautoscaler, omsagent-rs, tunnelfront and the metrics-sever.

After that i applied three deployments for my services, which all are deployed successfully.

Now, i want to get access to the Kubernetes Dashboard. I used the instruction which is described on

When i execute kubectl describe kubernetes-dashboard pod i get following:

And the logs from the pod say following:

Internal error occurred: No metric client provided. Skipping metrics.

CodePudding user response：

... I used the instruction which is described on https://artifacthub.io/packages/helm/k8s-dashboard/kubernetes-dashboard.

The dashboard needs a way to "cache" a small window of metrics collected from the metrics server. The instruction provided there doesn't have this enabled. You can run the following to install/upgrade kubernetes-dashboard with metrics scraper enabled:

helm upgrade -i kubernetes-dashboard/kubernetes-dashboard --name my-release \  
--set=service.externalPort=8080,resources.limits.cpu=200m,metricsScraper.enabled=true
