Java Monitoring on a VPC

[James Mcphee]

For jstat, you have to be a user with permission to the process.  In this
case, either the user the java process is running as, or root.  I use jstat
when I want to script things to watch them on the console.

For JMX, there are jvm arguments you can use to open it up to external
hosts, provide authentication, etc.  That will depend on the server you're
running and you should consult the documentation for that server.
