------------------------------------
Resolution: Not A Bug
> Nodetool proxyhistograms/cfhistograms still report latency as flat result
> -------------------------------------------------------------------------
>
> Key: CASSANDRA-12848
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12848
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Nutchanon Leelapornudom
> Priority: Major
> Labels: metrics
> Attachments: clientrequest-latency.png, image001.png
>
>
> Even patched in CASSANDRA-11752, nodetool
> proxyhistograms/cfhistograms(2.2)/tablehistograms(3.0,3.x) still report
> read/write latency as flat result. That cause Cassandra metric
> org.apache.cassandra.metrics.ClientRequest.Read/Write.Latency.xxpercentile
> report incorrect pattern.
> I have attached the result which I tested on cassandra 3.0.9. It indicate
> read latency as flat line whereas read count has a movement normally.
