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); }}

pom.xml

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
