> 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.
