Github user phunt commented on the issue: https://github.com/apache/zookeeper/pull/415 I didn't look at this in much depth yet but one obvious things struck me - you are missing the reset capability. See how we handle latency tracking in the beans. We try to keep jmx, 4lw and jetty interfaces (new in 3.5) in lock step wrt the metrics they provide. What do you think, do you want to try to include that in this patch or create separate JIRA(s) to track/address?
