My Tomcat 7 process, which I run on a server on Amazon EC2, has settings such as these in CATALINA_OPTS which should allow me to connect for JMX monitoring remotely:
-Dcom.sun.management.jmxremote.port=8086
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
However, connecting remotely does not work with either jconsole or jvisualvm. It just times out.
I've triple-checked that the EC2 security group allows access to the JMX remote port from my IP (and only from my IP).
Are there any settings missing?

Specify the java.rmi.server.hostname option too, so that it points to the public DNS name of your EC2 server:
-Djava.rmi.server.hostname=your.public.dnsThat was sufficient to get it working for me, but for more tips, try this blog post:
