Here are steps for newbe like me –

Non production test environment –
Disabling Security

To disable both password authentication and SSL (no security), set these system properties when you start the JVM:

com.sun.management.jmxremote.authenticate=false
com.sun.management.jmxremote.ssl=false

Warning: This configuration is insecure: any remote user who knows (or guesses) your JMX port number and host name will be able to monitor and control your Java application and platform. While it may be acceptable for development, it is not recommended for production systems.

To enable monitoring and management from remote systems, set this system property when you start the JVM:

com.sun.management.jmxremote.port=portNum

where portNum is the port number through which you want to enable JMX/RMI connections. Be sure to specify an unused port number.

Oops, wrong post, I meant to mention that on the post where you mentioned how you counted Cassandra’s SLOC.

Instead of using unmaintainable bash trickery to kind SLOC, use CLOC.

http://cloc.sourceforge.net/

It has support for many programming languages.

Java’s JMX coverage is pretty extensive and way out of scope here….
See for example http://java.sun.com/developer/technicalArticles/J2SE/jmx.html

A simple start would be to using the jconsole UI tool http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html
