Andrew Purtell commented on HBASE-19722:
----------------------------------------
While debugging elevated meta query rates we've noticed how clunky it is to do
that right now. In order to find top-N accesses by client identity or by table
name you have to toggle RpcServer to TRACE (only for a short time!), scrape the
resulting log output, extract via regex, rinse and repeat. It becomes apparent
a special set of metrics for the meta region, counting queries for particular
tables and by client identity, would be useful.

> Implement a meta query statistics metrics source, created whenever a
> regionserver starts hosting meta, removed when meta hosting moves. Provide
> views on top tables by request counts, top meta rowkeys by request count, top
> clients making requests by their hostname.
