Subject [jira] [Created] (ZOOKEEPER-3251) Add new server metric types: percentile counter and counter set

Jie Huang created ZOOKEEPER-3251:
------------------------------------

             Summary: Add new server metric types: percentile counter and counter set
                 Key: ZOOKEEPER-3251
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3251
             Project: ZooKeeper
          Issue Type: Sub-task
          Components: server
            Reporter: Jie Huang
             Fix For: 3.6.0


This will add three metric types:

AvgMinMaxCounterSet

AvgMinMaxPercentileCounter

AvgMinMaxPercentileCounterSet

The percentile metrics allow us to get a better sense of the latency distribution. They are
more expensive than AvgMinMax counters and are restricted to latency measurements for now.

The counter set allows the grouping of metrics such as write per namespace, read per namespace.
