Pod ephemeral storage reporting

Hi!
I have been looking for information on k8s ephemeral storage limit enforce and monitor. I have installed Prometheus operator and I manage only to get the limits I have set on the pod but not the usage. I have found on the net this k8s issue rejecting the kubelet ephemeral storage info, and [https://github.com/kubernetes/kubernetes/issues/78865](this k8s issue) that made me want to know if limit.ephemeral-storage was being reported on my k8s cluster.

Q: are this independent issues (available metrics and limits not being enforced)?
Q: Is it really a cardinality problem to have pod ephemeral storage usage?

Thank you guys in advance.

I personally don't think there is a cardinality problem. Sure it's roughly O(pods) but this is very useful data when there is a problem.
