turbine是聚合服务器发送事件流数据的一个工具，hystrix的监控中，只能监控单个节点，实际生产中都为集群，因此可以通过turbine来监控集群下hystrix的metrics情况，通过eureka来发现hystrix服务。
新建turbine项目
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);
}
}

application.yml
spring: application: name: turbineserver: port: 8000turbine: app-config: hello,helloClient ##需要监控的服务名 aggregator: clusterConfig: main ##需要监控的服务集群名 clusterNameExpression: metadata['cluster']eureka: instance: preferIpAddress: true statusPageUrlPath: /info.html client: serviceUrl: defaultZone: http://localhost:8761/eureka/
启动服务
helloserviceeureka 项目 appliation.yml 增加集群配置
更改为
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依赖包
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId></dependency>
同理ribboneureka 项目 application.yml 增加集群配置
更改后如下
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依赖包
RibbonEurekaApplication.java 增加注解
@EnableHystrix
启动项目
访问 localhost:8000/hystrixx 可以看到页面
注： turbine只能监控hystrix服务，不是hystrix服务，不能监控，如 hello这个服务虽然配置了集群，但是没有使用hystrix,所以不会受监控。
