Jonathan Gray commented on HBASE-3614:
--------------------------------------
I'm not sure if there is a JIRA yet, but some guys at FB did a bunch of work on
doing per-family metrics. They did work to dynamically generate new metric
names, etc.
I think we could work on this at the same time we start to think about using
the info for better load balancing and such. This could obviously come first.
> Expose per-region request rate metrics

> Key: HBASE-3614
> URL: https://issues.apache.org/jira/browse/HBASE-3614
> Project: HBase
> Issue Type: Improvement
> Components: metrics, regionserver
> Reporter: Gary Helmling
> Priority: Minor
>
> 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.
