SpringCloud分布式微服务b2b2c电子商务docker-hystrix-dashboard-turbine（九）

Hystrix的主要优点之一是它收集关于每个HystrixCommand的一套指标。Hystrix仪表板以有效的方式显示每个断路器的运行状况，通过Hystrix Dashboard我们可以在直观地看到各Hystrix Command的断路器是否打开，请求响应时间, 请求失败率，请求超时个数等等数据。但是只使用Hystrix Dashboard的话, 你只能看到单个应用内的服务信息, 这明显不够. 我们需要一个工具能让我们汇总系统内多个服务的数据并显示到Hystrix Dashboard上, 这个工具就是Turbine，了解springcloud架构可以加求求：三五三六二四七二五九，这节我们讨论一下，怎么用turbine+hystrix-dashboard监听两个消费者服务

一、监听模块microservice-consumer-movie-feign-with-hystrix断路器的运行状况

二、监听模块microservice-consumer-movie-ribbon-with-hystrix1断路器的运行状况

2.1、创建模块microservice-consumer-movie-ribbon-with-hystrix1

项目结构如下：
