And I learn SpringCloud Tutorial CHAPTER 9: docker-hystrix-b2b2c small e-commerce program

docker-hystrix-dashboard-turbine：

One of the main advantages is that it Hystrix collect a set of indicators for each of HystrixCommand.

Hystrix dashboard displays the health of each circuit breaker in an efficient manner, we can see each Hystrix Command breaker intuitively by Hystrix Dashboard is open, the response time of the request, the request failure rate data like the number of request times out.

But using only Hystrix Dashboard, you can only see the service information within a single application, which is obviously not enough. We need a tool that allows us to aggregate data multiple services within the system and displayed on Hystrix Dashboard, this tool is that Turbine,
this section we discuss, monitor how consumer services with two turbine + hystrix-dashboard

First, health monitoring module microservice-consumer-movie-feign-with-hystrix breaker

Second, health monitoring module microservice-consumer-movie-ribbon-with-hystrix1 breaker

2.1, create a module microservice-consumer-movie-ribbon-with-hystrix1
