             Summary: Ozone: Clarify the meaning of 
rpc.metrics.percentiles.intervals on KSM/SCM web ui
                 Key: HDFS-12558
                 URL: https://issues.apache.org/jira/browse/HDFS-12558
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HDFS-7240
            Reporter: Elek, Marton
            Assignee: Elek, Marton


In Ozone (SCM/KSM) web ui we have additional visualization if 
rpc.metrics.percentiles.intervals are enabled.

But according to the feedbacks it's a little bit confusing what is it exactly.

I would like to improve it and clarify how does it work.

1. I will to add  a footnote about these are not rolling windows but just 
display of the last fixed window.

2. I would like to rearrange the layout. As the different windows are 
independent, I would show them in different lines and group by the intervals 
and not by RpcQueueTime/RpcProcessingTime.
