Sergey Maslyakov commented on ZOOKEEPER-2422:
---------------------------------------------
According to the test report, the core tests break in an unrelated area of the
code. It seems to break in C++ unit tests. My change does not affect the C++
code, neither the breaking unit test uses the "mntr" 4lw, which I touched. Is
there a chance that the CI build picked up more than just my change?
> Improve health reporting by adding heap stats

> 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.
