Arpit Agarwal commented on HADOOP-10977:
----------------------------------------
Yes ideally ops will have that information however we have seen instances where
they don't or where they don't keep sufficient metrics history.
It would be useful to have metrics history available along with the logs.
> Periodically dump RPC metrics to logs

> Project: Hadoop Common
> Issue Type: Bug
> Components: metrics
> Affects Versions: 2.5.0
> Reporter: Arpit Agarwal

> It would be useful to periodically dump RPC/other metrics to a log file. We
> could use a separate async log stream to avoid contending with logging on hot
> paths.
> Placeholder Jira, this needs more thought.
