      Description

      We currently export metrics on request rates for each region server, and this can help with identifying uneven load at a high level. But once you see a given server under high load, you're forced to extrapolate based on your application patterns and the data it's serving what the likely culprit is. This can and should be much easier if we just exported request rate metrics per-region on each server.

      Dynamically updating the metrics keys based on assigned regions may pose some minor challenges, but this seems a very valuable diagnostic tool to have available.
