0045-一個Dashbord頁面監控多個消費者

1. 現狀

目前Hystrix項目可以監控消費者，但是每一個消費者就需要啓動一個監控頁面，很不方便，可以通過Turbine實現一個監控頁面，監控多個消費者

2. 改造Dashbord項目

2.1 pom依賴

增加turbine的依賴，其它和單機dashbord一致

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

    </dependency>

2.2 yml配置

監控集羣需要從Eureka-Server獲取消費者服務

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 # 服務名稱
    prefer-ip-address: true # 顯示ip地址

info: # 點擊註冊列表未服務出現的信息
  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 #需要監控的集羣名稱
  aggregator:
    cluster-config: default
  cluster-name-expression: new String("default")

2.3 主啓動類

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

2.4 測試

瀏覽器輸入http://localhost:10001/turbine.stream可以看到ping頁面表示成功
