Subject Re: zookeeper monitoring
Date Fri, 09 Jan 2015 18:37:42 GMT
Hi, I parse the zkServer.sh and make changes on
/etc/zookeeper/conf/environment

ZOOMAIN="-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
com.sun.management.jmxremote.port=20000
org.apache.zookeeper.server.quorum.QuorumPeerMain"

which was originally
ZOOMAIN="org.apache.zookeeper.server.quorum.QuorumPeerMain"

when I run it, it is like

root@DO-mq-dev:/etc/zookeeper/bin# ./zkServer.sh start
JMX enabled by default
Using config: /etc/zookeeper/conf/zoo.cfg
Starting zookeeper ... STARTED


But when I try to connect it by jconsole: 10.100.70.128:20000, but it fails
to connect, is there a way to confirm jmxremote port= 20000?

thanks

AL
