JConsole/VisualVM Failed To connect to GridGain node With IOException

Question

When I connect to GridGain node using JConsole or VisualVM, I get IOException.

How to overcome this?

Answer 1

Check if the hostname correctly resolves to the host address.

Run the command:

hostname -i

If it reports 127.0.0.1, JConsole/VisualVM would not be able to connect through JMX to the JVM running on that Linux machine. To fix this issue, edit /etc/hosts such that the hostname resolves to the host address.

You can also add system property to GridGain: -Djava.rmi.server.hostname=<hostname>
