Instrumenting Jersey

The metrics-jersey module provides InstrumentedResourceMethodDispatchAdapter, which allows you to instrument methods on your Jersey resource classes:

@Path("/example")
@Produces(MediaType.TEXT_PLAIN)
public class ExampleResource {
    @GET
    @Timed
    public String show() {
        return "yay";
    }
}

The show method in the above example will have a timer attached to it, measuring the time spent in that method.

Use of the @Metered and @ExceptionMetered annotations is also supported.
