Add pod/node labels

[benjaminjb]

I'm using metrics-server to keep track of certain CPU/memory usage, but I'd like to aggregate on pod labels. Any reason why we couldn't add labels to this section?

metrics-server/pkg/storage/podmetrics/reststorage.go

Lines 166 to 168 in 4f8dd2f

	Name: pod.Name,
	Namespace: pod.Namespace,
	CreationTimestamp: metav1.NewTime(time.Now()),

Changes to API exposed by metrics server should be proposed in https://github.com/kubernetes/metrics feel free to open issue there
Overall metrics-server API was not designed to do any aggregation.

Is this technically an API change since PodMetrics uses the standard Meta, which includes Name, Namespace, and Labels?

[serathius]

Yes, currently metrics API doesn't specify that Metrics object need to have same labels as object they represent.
