Subject [jira] [Commented] (ZOOKEEPER-2422) Improve health reporting by adding heap stats
Date Tue, 03 May 2016 17:11:12 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-2422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15269108#comment-15269108

Chris Nauroth commented on ZOOKEEPER-2422:
------------------------------------------

Hello [~evolvah].

This was a failure in TestReconfig.cc, which covers dynamic ensemble reconfiguration through
the C client.  We have seen intermittent failures from a few of the reconfiguration test suites
on both the Java and C side.  As of right now, we don't have a successful diagnosis of the
problem, so I expect we'll continue to see this intermittently from future pre-commit builds.

This is unrelated to your patch, and you don't need to take any further action in response
to the failure within the scope of this patch.  Reviewers will be able to make a judgment
call and see that certain patches, like this one, don't touch the reconfiguration logic at
all.

> In order to improve remote monitoring of the ZooKeeper instance using tools like Icinga/NRPE,
it is very desirable to expose JVM heap stats via a light-weight interface. The "mntr" 4lw
is a good candidate for this.
