I used two ways to start jconsole on a remote ec2 server. Both require access to the private IP of the instance.

What I've found is that the ubuntu ami on AWS doesn't have an X window server by default. The first one relies on ssh to the instance via the private IP along with installing a X windows server on your workstation. On the mac, I use XQuartz. When I was using Windows, I installed Xming.

SSH with the -X or -Y flag like so: ssh -Y -i /path/to/my.pem [email protected] where you use your own keypair and private IP address.

At the bash prompt on the instance, type ubuntu@ip-10-11-12-13:~$ jconsole to start jconsole. XQuartz will start up and the jconsole window will be displayed on your local desktop.

Second, if you have jmx enabled and the jmx port opened in the security group, you can run jconsole on your local machine and connect to the remote process.

Hopefully I've read your question correctly.
