Eclipse配置運行SpringCloud（Hoxton + 2.2.4）微服務框架 + 搭建聚合監控Turbine

在複雜的分佈式系統中，相同服務的節點經常需要部署上百甚至上千個，很多時候，我們希望能夠把相同服務的節點狀態以一個整體集羣的形式展現出來，這樣可以更好的把握整個系統的狀態。 爲此，Netflix提供了一個開源項目（Turbine）來提供把多個hystrix.stream的內容聚合爲一個數據源供Dashboard展示。

創建聚合監控服務

添加依賴包文件POM.xml

配置application.yml文件

spring:
  application:
    name: springcloud-turbine
  freemarker:
    prefer-file-system-access: false
  security:
    user:
      name: admin
      password: 123456
    
server:
  port: 8110

eureka:
  instance:
    hostname: eureka-turbine.com
    instance-id: eureka-turbine
  client:
    service-url:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@eureka-peer1.com:8897/eureka/,http://${spring.security.user.name}:${spring.security.user.password}@eureka-peer2.com:8898/eureka/,http://${spring.security.user.name}:${spring.security.user.password}@eureka-peer3.com:8899/eureka/

turbine:
  aggregator:
    #需要監控的服務集羣名
    cluster-config: default
  #需要監控的服務名
  app-config: springcloud-ribbon, springcloud-feign
  cluster-name-expression: new String("default")
# instanceUrlSuffix:
    #key是clusterConfig集羣的名字，value是hystrix監控的後綴，springboot2.0爲actuator/hystrix.stream
#   default: actuator/hystrix.stream

修改C:\Windows\System32\drivers\etc\hosts

127.0.0.1 eureka-ribbon.com eureka-feign.com eureka-turbine.com

添加聚合監控服務啓動類

• TurbineApplication.java

在程序的啓動類加上註解@EnableTurbine和@EnableHystrixDashboard

package org.springcloud.turbine;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.EnableTurbine;

@SpringBootApplication
@EnableTurbine
@EnableHystrixDashboard
public class TurbineApplication {

    public static void main(String[] args) {
        SpringApplication.run(TurbineApplication.class, args);
    }
}

依次啓動項目

springcloud-eureka-cluster-peer1
springcloud-eureka-cluster-peer2
springcloud-eureka-cluster-peer3
springcloud-eureka-provider1
springcloud-eureka-provider2
springcloud-eureka-provider3
springcloud-ribbon
springcloud-feign

在瀏覽器訪問先訪問http://eureka-ribbon.com:8100/hi，http://eureka-feign.com:8101/hi
然後再訪問http://eureka-turbine.com:8110/turbine.stream，瀏覽器會顯示熔斷器的數據指標

訪問http://eureka-turbine.com:8110/hystrix

依次填入http://eureka-turbine.com:8110/turbine.stream等，點擊 Moniter Stream

可以看到這個頁面聚合了springcloud-ribbon和springcloud-feignt的Hystrix Dashboard數據。
