Wei-Chiu Chuang updated RATIS-1885:
-----------------------------------
Summary: Incorrect clientWriteRequest timer usage (was: Incorrect
clientWriteRequest timer)
> Incorrect clientWriteRequest timer usage
> ----------------------------------------
>
> Key: RATIS-1885
> URL: https://issues.apache.org/jira/browse/RATIS-1885
> Project: Ratis
> Issue Type: Bug
> Components: metrics
> Affects Versions: 2.5.1
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Major
>
> clientWriteRequest timer measures the time from receiving the client request
> until the leader responds back.
> But this timer is only initialized when the leader responds, so the timer is
> always close to zero.
> https://github.com/apache/ratis/blob/branch-2/ratis-server/src/main/java/org/apache/ratis/server/impl/RaftServerImpl.java#L840
> The bug is accidentally fixed in 3.0.0 by RATIS-1693. But for users of 2.x
> this may still be worth fixing.
