Hi @rp346,
+1, I have the same issue.
If I use prometheus + grafana, i can see pods metrics.
So, the problem seem be due to metricbeats ...
The serviceAccount can't list some ressources:
Failed to list *v1beta1.ReplicaSet: replicasets.apps is forbidden: User "system:serviceaccount:kube-system:metricbeat" cannot list resource "replicasets" in API group "apps" at the cluster scope
An issue is created here
The problems seem be fix in future release
