turbine是聚合服務(wù)器發(fā)送事件流數(shù)據(jù)的一個(gè)工具，hystrix的監(jiān)控中，只能監(jiān)控單個(gè)節(jié)點(diǎn)，實(shí)際生產(chǎn)中都為集群，因此可以通過turbine來監(jiān)控集群下hystrix的metrics情況，通過eureka來發(fā)現(xiàn)hystrix服務(wù)。

啟動項(xiàng)目
訪問 localhost:8000/hystrixx 可以看到頁面
注： turbine只能監(jiān)控hystrix服務(wù)，不是hystrix服務(wù)，不能監(jiān)控，如 hello這個(gè)服務(wù)雖然配置了集群，但是沒有使用hystrix,所以不會受監(jiān)控。
