Elliott Clark commented on HBASE-6404:
--------------------------------------
Moving things to MetricsHistogram (or whatever the new metrics2 class name will
be) will do this. However it comes with a cost so we should be judicious about
it's usage.
> Collect p50, p75 and p95 stats

> Project: HBase
> Issue Type: Improvement
> Components: monitoring
> Reporter: Arjen Roodselaar
> Assignee: Liyin Tang
>
> Stats in current versions of HBase are currently exposed as avg, min and max.
> This gives a skewed view of performance as the outliers are usually the
> indicators of problems. Please revise the stats collection framework to use
> true buckets and expose the p50, p75 and p95 values of these buckets through
> JMX.
