I have installed the kubernetes dashboard on my Kubernetes cluster using the following:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

I've installed metrics-server v0.3.6, once using the stable/metrics-server helm chart and another using:

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.3.6/components.yaml

However, I'm unable to see graphs for CPU/memory usage show up on my dashboard UI. I have tried adding the following in my metrics-server deployment but still is not working for me. Any help would be greatly appreciates.

hostNetwork: enabled
args: 
  - --deprecated-kubelet-completely-insecure
  - --kubelet-insecure-tls
  - --kubelet-preferred-address-types=InternalIP

When I run:

kubectl top node --v=10
...
