Github user lvfangmin commented on the issue: https://github.com/apache/zookeeper/pull/582 One question is are we just publishing the raw data to the external metric report system, or we need to do our aggregation to find out values like min/avg/max? If we need to aggregate before report, it might be useful to take a look at ZOOKEEPER-3098, which added AvgMinMaxCounter, SimpleCounter. We also added percentile counter, etc, which will be contributed later.
