Jconsole cannot connect

Fix found here: You need to pass to the VM:

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false

-- Edit - Fixed the =fals error mentioned in comments.

Adding below property as VM argument in Run Configurations --> Arguments --

-Dcom.sun.management.jmxremote=true

In my case, I also had to add this option to get Jconsole to connect to the process.

-Djava.rmi.server.hostname=localhost

Remote JConsole

Add the following parameters to your java Application and run it

-Djava.rmi.server.hostname=DOMAIN_PUBLIC_URL  -Dcom.sun.management.jmxremote.port=PORTNUMBER -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

DOMAIN_PUBLIC_URL - Like your instance public address

PORTNUMBER - 9955

Launch jconsole in your ubuntu from terminal command and go to remote connection and paste the DOMAIN_PUBLIC_URL and PORT and Connect it without username and password like insecure connection.

Make sure to expose the port number on your AWS Server Instance.
