Re: Four letter word command to get memory usage (patch included)

2019-02-14 Thread Andor Molnar
Hi Bram,

Thanks for the contribution. Please follow Enrico's instructions on how to
officially contribute on the ZooKeeper project. Here's our guidelines:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/HowToContribute

Additionally, 4lw has become deprecated, so we won't accept new features on
that. You can add new Jetty command or JMX whichever suits you best. IMHO
the best would be add to them both.

Thanks,
Andor

It is also worth noting that we are also working on a new metrics
system and JVM information will be included in the new system.
