Question: I am using Spring Cloud and @EnableZuulProxy Is it possible to monitor all routes configured in application.yml using hystrix via /hystrix.stream? In the example below I would like to have a simple way to monitor all request made to the down stream product service. I understand that I can do this on the product service itself, but is it possible to monitor Zuul request. This would be useful for any down stream services that are not owned (third party) and cannot be annotated with the @HystrixCommand.

`zuul:
 routes:
 item:
 serviceId: product
 path: /product/**`

Answer: 
The simple answer is yes. Add `spring-cloud-starter-hystrix` and add `@EnableCircuitBreaker` to your main class. That will enable `/hystrix.stream`. Zuul uses hystrix when forwarding to other services.
I had the same issue and changing `@EnableCircuitBreaker` to `@EnableHystrix` fixed the problem.

With `@EnableHystrix` I can see all the routed calls on the Hystrix dashboard.

**Update**

See comment below, this is indeed not the fix.
