Subject Missing MBeans in JMX
Date Tue, 21 Oct 2014 01:19:11 GMT
Hi,

I'm running ZK 3.4.6 and am having difficulty monitoring it with SPM
<http://sematext.com/spm/>, which is showing errors like "Can't read jmx
attribute javax.management.AttributeNotFoundException: No such attribute:
NumAliveConnection."

So I used JMXC <https://github.com/sematext/jmxc> to dump everything this
ZK has in JMX, but was surprised to see NO ZK-specific MBeans in the JMX
what so ever!

Is there something one has to do to enable JMX?

This is how this ZK is running:

/srv/zookeeper/jdk/bin/java -Dzookeeper.log.dir=/srv/zookeeper/log
-Dzookeeper.root.logger=INFO,CONSOLE -cp
/srv/zookeeper/zookeeper/bin/../build/classes:/srv/zookeeper/zookeeper/bin/../build/lib/*.jar:/srv/zookeeper/zookeeper/bin/../lib/slf4j-log4j12-1.6.1.jar:/srv/zookeeper/zookeeper/bin/../lib/slf4j-api-1.6.1.jar:/srv/zookeeper/zookeeper/bin/../lib/netty-3.7.0.Final.jar:/srv/zookeeper/zookeeper/bin/../lib/log4j-1.2.16.jar:/srv/zookeeper/zookeeper/bin/../lib/jline-0.9.94.jar:/srv/zookeeper/zookeeper/bin/../zookeeper-3.4.6.jar:/srv/zookeeper/zookeeper/bin/../src/java/lib/*.jar:/srv/zookeeper/zookeeper/bin/../conf:*
-Dcom.sun.management.jmxremote.port=3000
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.local.only=false*
org.apache.zookeeper.server.quorum.QuorumPeerMain
/srv/zookeeper/zookeeper/bin/../conf/zoo.cfg

Is some key property missing here?

Thanks,
Otis
