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;

/**

@SpringBootApplication

@EnableTurbine

@EnableHystrix

@EnableHystrixDashboard

public class TurbineApplication{

public static void main(String[] args) {

SpringApplication.run(TurbineApplication.class,args);

}

}

application.yml

spring:

application:

name: turbine

server:

port: 8000

turbine:

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: hello

server:

port: 9001

eureka:

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: 3

logging:

level:

com:

netflix:

eureka: OFF

discovery: OFF

pom.xml增加hystrix依赖包

org.springframework.cloud

spring-cloud-starter-hystrix

同理ribboneureka 项目 application.yml 增加集群配置

更改后如下

spring:

application:

name: helloClient

server:

port: 20000

eureka:

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: 3

logging:

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。
