stack commented on HBASE-20672:
-------------------------------
[~jain.ankit] Can you say why we need these extra counters (I'm wary adding
counters because we already spend a bunch of our processing time counting)?
What is "monitoring interval" (from RN)? How is it set? Is it an hbase thing?
Or is it a monitoring system thing? Thanks.
> Create new HBase metrics ReadRequestRate and WriteRequestRate that reset at
> every monitoring interval

> Hbase currently provides counter read/write requests (ReadRequestCount,
> WriteRequestCount). That said it is not easy to use counter that reset only
> after a restart of the service, we would like to expose 2 new metrics in
> HBase to provide ReadRequestRate and WriteRequestRate at region server level.
