    • Release Note:
      Adds per-user metrics for reads/writes to each RegionServer. These metrics are exported by default. hbase.regionserver.user.metrics.enabled can be used to disable the feature if desired for any reason.

      Description

      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.
