Run this app as a normal Spring Boot app and then go to the home page
in a browser. If you run from this project it will be on port 7979
(per the application.yml). On the home page is a form where you can
enter the URL for an event stream to monitor, for example (the
customers service running locally):
http://localhost:9000/hystrix.stream. Any app that uses
@EnableHystrix will expose the stream.
To aggregate many streams together you can use the Turbine sample.
