Eclipse配置运行SpringCloud（Hoxton + 2.2.4）微服务框架 + 搭建聚合监控Turbine

在复杂的分布式系统中，相同服务的节点经常需要部署上百甚至上千个，很多时候，我们希望能够把相同服务的节点状态以一个整体集群的形式展现出来，这样可以更好的把握整个系统的状态。 为此，Netflix提供了一个开源项目（Turbine）来提供把多个hystrix.stream的内容聚合为一个数据源供Dashboard展示。

创建聚合监控服务

添加依赖包文件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:
    #需要监控的服务集群名
    cluster-config: default
  #需要监控的服务名
  app-config: springcloud-ribbon, springcloud-feign
  cluster-name-expression: new String("default")
# instanceUrlSuffix:
    #key是clusterConfig集群的名字，value是hystrix监控的后缀，springboot2.0为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

添加聚合监控服务启动类

• TurbineApplication.java

在程序的启动类加上注解@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);
    }
}

依次启动项目

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

在浏览器访问先访问http://eureka-ribbon.com:8100/hi，http://eureka-feign.com:8101/hi
然后再访问http://eureka-turbine.com:8110/turbine.stream，浏览器会显示熔断器的数据指标

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

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

可以看到这个页面聚合了springcloud-ribbon和springcloud-feignt的Hystrix Dashboard数据。
