Measuring total number of active (HTTP) connections with Metrics in Dropwizard application

Question

I have a Dropwizard application I am working with where I need to be able to monitor for active HTTP connections. I know Metrics provides classes for Instrumenting Jetty, and of interest to me is measuring total number of active connections....however the javadoc doesn't help me much, and I can't find any examples of how this specific functionality is implemented. Does anyone have any examples they can share?

I'm not sure what your exact use-case is but if you just need to be able to see active connections I think the simplest solutions are just using monitoring solutions like JMX, Datadog, New Relic, or Appdynamics. If you need it in the code I think you'd need to manually implement something. I'd recommend StatsD or Redis is that's the path you go down.
