Quick enable simple password protected Remote JMX with tomcat

You need to do following configuration to enable Remote JMX monitoring on tomcat server.

1. Copy jmxremote.password.template located at JRE_HOME/lib/management inside the same folder with the name jmxremote.password.  
2. Edit this jmxremote.password file and uncomment last two lines starts with monitorRole and controleRole and instead of QED and R&D set some good password for both of them.
3. Change directory to CATALINA_HOME/bin from where you start the tomcat.
4. You will find setenv.sh (if you don't find it create one) and add following line inside file CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.port=9000 -Djava.rmi.server.hostname=127.0.0.1 -Dcom.sun.management.jmxremote.ssl=false"
5. Here in above line you need to set proper ip address which is accessible from remote machine to -Djava.rmi.server.hostname and set available port number to -Dcom.sun.management.jmxremote.port 
6. Once all this settings are done restart / start tomcat.

Above steps will enable remote JMX on this JVM. To monitor it using jconsole from remote machine follow below steps from remote machine.

1. Start jconsole $ jconsole
2. Select Remote Process option and enter "<remote ip address>:<port>", specify username as monitorRole or controleRole and password that you set inside jmxremote.password file for corresponding user.

This should start remote monitoring of remote JVM tomcat.
