There are 2 metrics already captured in the push server metrics endpoint.

More info here

I'm interested in any suggestions on what else could/should be included in the metrics endpoint.

CPU/RAM will already be captured by heapster in openshift

Any thoughts on using the same approach as keycloak & including default exports

?

Is there anything else specific to administering a push server that would be useful?
