Connecting using jconsole to a java process without jmx parameters

Question

I have a java program in a weird condition where it has stopped running a certain thread.

I would like to connect to it using JMX, but I didn't provide the JMX arguments.

I could restart but then I would loss the information of the current condition.

I know that on Windows it can connect with jconsole on localhost without parameters, but my java app is running on a Linux server.

So any ideas on how to still be able to connect even without jmx parameters?

Answer 1

JConsole works on linux also. If the linux server have xhost or some remote displaying capability, I would just run jconsole on the linux server.

If you didn't enable JMX when the java program was started, you would not be able to connect remotely via JMX.

Answer 2

I found out that there is an option to dump the threads:

kill 3

Used it and found the reason.

Thank you.
