> 为什么有了一个监控，为啥，又来一个监控呢，由于断路器监控(Hystrix Dashboard)只能查看一个app的情况，当我们有多个app的情况，就需要通过Turbine这个聚合监控来解决了。聚合监控搭建步骤：1、配置pom.xml文件，2、配置application.yml ，设定监控的app,3、配置启动类。

### 项目架构 ###

其中app1和app2，就是[SpringCloud之断路器监控(Hystrix Dashboard) |第六章 -yellowcong][SpringCloud_Hystrix Dashboard_ _ -yellowcong]配置的短路监控。复制了两份而已 。

## 搭建聚合监控系统(Hystrix Turbine) ##

聚合监控搭建步骤：1、配置pom.xml文件，2、配置application.yml ，设定监控的app,3、配置启动类。

### 1、配置pom.xml ###

这个地方，我要说点，这个地方，需要导入的依赖如下，我就被坑了，人家都是少导入了`spring-cloud-starter-eureka-server`依赖类。

        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka-server</artifactId>

    <exclusions>
       <exclusion>
           <groupId>javax.servlet</groupId>
           <artifactId>servlet-api</artifactId>

                </plugin>
            </plugins>
        </build>
    </project>

### 2、配置application.yml ###

配置监控的服务对象，配置注册中心

#配置eureka 的注册中心
    eureka:
      client:
        serviceUrl:
          defaultZone: http://yellowcong.com:8761/eureka/
    
    # 注册服务的端口
    server:
      port: 8764
    turbine:
      aggregator:
        clusterConfig: default   # 指定聚合哪些集群，多个使用","分割，默认为default。可使用http://.../turbine.stream?cluster={clusterConfig之一}访问
      appConfig: eureka-hystrix-app1,eureka-hystrix-app2  ### 配置Eureka中的serviceId列表，表明监控哪些服务
      clusterNameExpression: new String("default")
      # 1. clusterNameExpression指定集群名称，默认表达式appName；此时：turbine.aggregator.clusterConfig需要配置想要监控的应用名称
      # 2. 当clusterNameExpression: default时，turbine.aggregator.clusterConfig可以不写，因为默认就是default
      # 3. 当clusterNameExpression: metadata['cluster']时，假设想要监控的应用配置了eureka.instance.metadata-map.cluster: ABC，则需要配置，同时turbine.aggregator.clusterConfig: ABC
    
    #配置当前服务的名称
    spring:
      application:
        name: service-turbine

指定监控的app

### 3、配置启动类 ###

启动类，只有两个注解，你没有看错,没有配置`@EnableEurekaClient`,但是最后服务任然注册到了Eureka上，说明源码里面有配置这个注解

package com.yellowcong.main;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.turbine.EnableTurbine;
    
    /** * @author yellowcong */
    @SpringBootApplication
    @EnableTurbine
    public class ConfigMain { 
    
        public static void main(String[] args) {
            SpringApplication.run(ConfigMain.class, args);
        }
    }

虽然我们没有配置服务注册到Eurake，但是启动项目后，还是注册到服务上了，说明源码里面有注解，设定注册到Eurake

### 4、启动测试 ###

<table> 
 <thead> 
  <tr> 
   <th>项目名</th> 
   <th>启动顺序</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>eureka-server</td> 
   <td>1</td> 
  </tr> 
  <tr> 
   <td>eureka-hystrix-app1</td> 
   <td>2</td> 
  </tr> 
  <tr> 
   <td>eureka-hystrix-app2</td> 
   <td>3</td> 
  </tr> 
  <tr> 
   <td>eureka-hystrix-turbine</td> 
   <td>4</td> 
  </tr> 
 </tbody> 
</table>

访问[http://yellowcong.com:8764/hystrix][http_yellowcong.com_8764_hystrix] 访问到管控台，设置聚合监控的路径是 [http://yellowcong.com:8764/turbine.stream][http_yellowcong.com_8764_turbine.stream]  
![这里写图片描述][SouthEast 3]

测试聚合登录，我登录上后，疯狂访问 [http://yellowcong.com:8763/hi/xxx][http_yellowcong.com_8763_hi_xxx]和 [http://yellowcong.com:8762/hi/xxx][http_yellowcong.com_8762_hi_xxx]，看到管控台的数据也是一路飙升啊。  
![这里写图片描述][SouthEast 4]

可以看到服务是2台主机
