Andrew Purtell commented on HBASE-15519:
----------------------------------------
Pardon the potentially ignorant question. I'm on vacation with just a phone.
Does this work include exporting at least a subset of per user accouting in
ClusterStatus? It would be fine to do this as a follow up of course. Reason I
ask is hbtop receives its telemetry from ClusterStatus and an obvious and
important enhancement for that tool would be a display mode for top N user or
top N client activity by server or region (or table or namespace aggregates).

> Per-user metrics will be useful in multi-tenant cases where we can emit
> number of requests, operations, num RPCs etc at the per-user aggregate level
> per regionserver. We currently have throttles per user, but no way to monitor
> resource usage per-user.
> Looking at these metrics, operators can adjust throttles, do capacity
> planning, etc per-user.
