> Capture Scan RPC processing time and queuing time in Scan Metrics
> -----------------------------------------------------------------

> Key: HBASE-29494
> URL: https://issues.apache.org/jira/browse/HBASE-29494
> Project: HBase
> Issue Type: Improvement
> Reporter: Sanjeet Malhotra
> Assignee: Sanjeet Malhotra
> Priority: Minor
> Labels: pull-request-available
> Fix For: 2.7.0, 3.0.0-beta-2, 2.6.4, 2.5.13
>
>
> Currently, RPC processing time and queuing time are captured in JMX metrics
> at Region Server level. But having these captured in Scan metrics will be
> helpful to analyse RPC processing and queuing time for each Scan
> individually. High RPC queuing time could indicate slowness on server side
> and unexpected big diff. b/w processing time and FS read time can identify
> slowness in RS process.
>
> The aim is to backport this Jira to HBase 3, HBase 2, 2.6 and 2.5
