### 1. 现状 ###

目前Hystrix项目可以监控消费者，但是每一个消费者就需要启动一个监控页面，很不方便，可以通过Turbine实现一个监控页面，监控多个消费者

### 2. 改造Dashbord项目 ###

#### 2.1 pom依赖 ####

增加turbine的依赖，其它和单机dashbord一致

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
        </dependency>
    </dependencies>

#### 2.2 yml配置 ####

监控集群需要从Eureka-Server获取消费者服务

server:
      port: 10001
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://eureka-server-7001:7001/eureka/,http://eureka-server-7002:7002/eureka/,http://eureka-server-7003:7003/eureka/
      instance:
        instance-id: eureka-consumer-hystrix-dashbord-10001 # 服务名称
        prefer-ip-address: true # 显示ip地址
    
    info: # 点击注册列表未服务出现的信息
      app.name: springcloud
      company.name: www.honor.com
      build.artifactId: @project.artifactId@
      build.version: @project.version@
    
    spring:
      application:
        name: eureka-consumer-hystrix-dashbord
    
    turbine:
      combine-host-port: true
      app-config: EUREKA-CONSUMER #需要监控的集群名称
      aggregator:
        cluster-config: default
      cluster-name-expression: new String("default")

#### 2.3 主启动类 ####

@SpringBootApplication
    @EnableHystrixDashboard
    @EnableTurbine
    public class EurekaConsumeHystrixDashbord10001 { 
        public static void main(String[] args) { 
            SpringApplication.run(EurekaConsumeHystrixDashbord10001.class, args);
        }
    }

#### 2.4 测试 ####

浏览器输入http://localhost:10001/turbine.stream可以看到ping页面表示成功
