I'm trying to troubleshoot a possible memory leak on my Guacamole docker container. I have enabled JMX and this works fine when I'm running the container locally on my MacBook Pro. When I run the same container on my Unraid server and export the JMX port VisualVM says it cannot connect. This is tomcat's setenv.sh file:

#!/bin/sh

export JAVA_OPTS="-Dcom.sun.management.jmxremote.rmi.port=9090 \
                  -Dcom.sun.management.jmxremote=true \
                  -Dcom.sun.management.jmxremote.port=9090 \
                  -Dcom.sun.management.jmxremote.ssl=false \
                  -Dcom.sun.management.jmxremote.authenticate=false \
                  -Dcom.sun.management.jmxremote.local.only=false \
                  -Djava.rmi.server.hostname=localhost"

 

I figured this out. I needed to set java.rmi.server.hostname to the IP of my Unraid server. With it set to localhost it will only allow connections from localhost.
