Setting up JMS for VisualVM

Add this in OH /usr/share/openhab2/runtime/binsetenv script:

EXTRA_JAVA_OPTS_COMMON="-Djava.rmi.server.hostname=192.168.0.2 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9199 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false ..."

Set up ssh to forward the port:

ssh -v -D 9696 user@hostname

or

ssh -N -f -L 9199:localhost:9199 user@hostname

Add a JMX connector in VisualVM for localhost:9199
