code: @Override
  	public void bind(RestExpress server)
  	{
  		this.activeRequestsCounter = metrics.counter("active-requests");
  	    this.allExceptionsCounter = metrics.counter("all-exceptions");
  	    this.allTimesTimer = metrics.timer("all-times");
  	}
docs: This is called by RestExpress during it's bind() operation--right before it starts listening.
