Andrew Purtell commented on HBASE-15519:
----------------------------------------
Point in time is suitable for the hbtop case and even for display in shell
“status ‘detailed’” output, so that lines up. Thank you. Agree also the other
issue is good for tracking the needed ClusterStatus changes.
> Add per-user metrics

> 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.
