Subject zookeeper monitoring
Date Fri, 09 Jan 2015 00:02:02 GMT
Hi, all

I've just figured out the monitoring of kafka by jconsole, I want to do the
same thing to zookeeper. Zookeeper site says "The class
*org.apache.zookeeper.server.quorum.QuorumPeerMain* will start a JMX
manageable ZooKeeper server. This class registers the proper MBeans during
initalization to support JMX monitoring and management of the instance. See
*bin/zkServer.sh* for one example of starting ZooKeeper using
QuorumPeerMain."

I found when I type:
root@pof-kstorm-dev1:/etc/kafka# zkServer.sh start
JMX enabled by default
Using config: /etc/zookeeper/conf/zoo.cfg
Starting zookeeper ... STARTED

Seems JMX is enabled by default, by checking the zkServer.sh,

ZOOMAIN="-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.local.only=$JMXLOCALONLY
org.apache.zookeeper.server.quorum.QuorumPeerMain"

here
-Dcom.sun.management.jmxremote.local.only=$JMXLOCALONLY , should I change a
jmxport here, or what is the default jmx_port number for zookeeper?

thanks
