Spring Cloud 之服务监控 turbine（六）

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

@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。
