簡介

Hystrix的主要優點之一是它收集關於每個HystrixCommand的一套指標。Hystrix儀表板以有效的方式顯示每個斷路器的運行狀況，通過Hystrix Dashboard我們可以在直觀地看到各Hystrix Command的斷路器是否打開，請求響應時間, 請求失敗率，請求超時個數等等數據。但是只使用Hystrix Dashboard的話, 你只能看到單個應用內的服務信息, 這明顯不夠. 我們需要一個工具能讓我們匯總系統內多個服務的數據並顯示到Hystrix Dashboard上, 這個工具就是Turbine，這節我們討論一下，怎麽用turbine+hystrix-dashboard監聽兩個消費者服務

一、監聽模塊microservice-consumer-movie-feign-with-hystrix斷路器的運行狀況

二、監聽模塊microservice-consumer-movie-ribbon-with-hystrix1斷路器的運行狀況

2.1、創建模塊microservice-consumer-movie-ribbon-with-hystrix1

項目結構如下：
