How to enable the JConsole remote connection to dropwizard server to watch JMX counter

[Rocky Fan]

I build a service which is based on dropwizard. I want to see the performance count for the service.

I am able to use JConsole in local to connect the service instance and watch the counter. But I don't see any document to show up how to make configure in dropwizard to listen JConsole port so I can use JConsole to remote into the box and watch the counter.

If you could provide a sample configure, that would be great. Thanks.

Rather than referring to reference documentation (which has not helped me even though I tried several of the things in it), does anybody actually have examples?  Is the JmxReporter started by default?  If so, is it already on a port?  If so, can I not change that port with the -D parm?  If it is, how do I find what port it started on?

I figured it out from Mark Turansky's blog:

-Dcom.sun.management.jmxremote.port=$JMX_PORT -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

...to get started.

I always suggest to use Jolokia. Its as simple as adding jolokia-core and declaring its servlet. Once its done, one could use Hawt (http://www.hawt.io/) to query JMX via HTTP
