Anoop Sam John commented on HBASE-19035:
----------------------------------------

+1. Lets unify it where the metrics are updated.  For writes, seems we update at region and
for reads, it is at RsRpcServices , one layer up Region.!

> Region interface is exposed to coprocessor. So coprocessor use getScanner to get a region
scanner to read data. But the scan metrics was only updated in region server level. So we
will miss some scan metrics for the read from coprocessor.
