public class HystrixMetricsEventStreamHandler
extends java.lang.Object
implements ratpack.handling.Handler

A Handler that streams Hystrix metrics in text/event-stream format.

This handler should be bound to an application path, and most likely only for the GET method…

 import ratpack.hystrix.HystrixMetricsEventStreamHandler;
 import static org.junit.Assert.*;

 assertTrue(chain instanceof ratpack.handling.Chain);
 chain.get("admin/hystrix.stream", new HystrixMetricsEventStreamHandler());
 

This handler can be used in conjunction with Server Sent Event based clients such as the Hystrix Dashboard and Turbine to consume the metrics being reported by your application in realtime.
