Troubleshooting
In case JMX Agent is not active by default and jconsole can't connect,
you can enable remote connectivity by passing the following paramaters when
starting java:
-Dcom.sun.management.jmxremote.port=9005
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
Please note the security implications, as noted during the workshop!
