Unable to fetch metrics from Kubelet

Error: 

Failed to scrape node" err="Get \"https://192.168.56.110:10250/metrics/resource\": dial tcp 192.168.56.110:10250: connect: connection refused" node="k8s-node1"

The above given error will come , while "metrics-server" is trying to scrape metrics from Kubelet.

Solution: 

To solve this issue we need to set the kubelet flag "--authorization-mode=AlwaysAllow" and "anonymous enabled=true" , and metrics-server flag "--kubelet-insecure-tls".

kubelet-config-for-metrics

metrics-server-for-metrics

After that restart Kubelet Servics.

Thats it.
