turbine是聚合服務器發送事件流數據的一個工具，hystrix的監控中，只能監控單個節點，實際生產中都為集群，因此可以通過turbine來監控集群下hystrix的metrics情況，通過eureka來發現hystrix服務。
新建turbine項目
TurbineApplication.java
package turbine;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.hystrix.EnableHystrix;import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;import org.springframework.cloud.netflix.turbine.EnableTurbine;/** * Created by sai.luo on 2017/4/26. */@SpringBootApplication@EnableTurbine@EnableHystrix@EnableHystrixDashboardpublic class TurbineApplication{ public static void main(String[] args) { SpringApplication.run(TurbineApplication.class,args); }}pom.xml

application.yml
spring: application: name: turbineserver: port: 8000turbine: app-config: hello,helloClient ##需要監控的服務名aggregator: clusterConfig: main ##需要監控的服務集群名clusterNameExpression: metadata['cluster']eureka: instance: preferIpAddress: true statusPageUrlPath: /info.html client: serviceUrl: defaultZone: http://localhost:8761/eureka/
啟動服務
helloserviceeureka 項目appliation.yml 增加集群配置
更改為
spring: application: name: helloserver: port: 9001eureka: instance: lease-renewal-interval-in-seconds: 3 lease-expiration-duration-in-seconds: 5 metadata-map: cluster: main client: serviceUrl: defaultZone: http://localhost:8761/eureka/ registry-fetch-interval-seconds: 3logging: level: com: netflix: eureka: OFF discovery: OFF
pom.xml增加hystrix依賴包
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId></dependency>
同理ribboneureka 項目application.yml 增加集群配置
更改後如下
spring: application: name: helloClientserver: port: 20000eureka: instance: lease-renewal-interval-in-seconds: 3 lease-expiration-duration-in-seconds: 5 metadata-map: cluster: main client: serviceUrl: defaultZone: http://localhost:8761/eureka/ registry-fetch-interval-seconds: 3logging: level: com: netflix: eureka: OFF discovery: OFF
pom.xml增加hystrix依賴包
RibbonEurekaApplication.java 增加註解
@EnableHystrix
啟動項目
訪問localhost:8000/hystrixx 可以看到頁面
注： turbine只能監控hystrix服務，不是hystrix服務，不能監控，如hello這個服務雖然配置了集群，但是沒有使用hystrix,所以不會受監控。
