# hystrix + turbine 集群聚合监控 #

hystrix dashboard 一次只能监控一个服务实例，使用 turbine 可以汇集监控信息，将聚合后的信息提供给 hystrix dashboard 来集中展示和监控

Turbine是hystrix监控数据的聚合

Turbine可以聚合多台服务器的监控数据，聚合后交给仪表盘进行展现，同时监控多台服务器。

搭建 Turbine 服务：

1.  新建项目 sp10-turbine
2.  Turbine依赖
3.  yml配置：

`app-config`指定要聚合的服务，order-service, service2,service3

`cluster-name-expression`给聚合后的数据起一个集群名，一般用 default

1.  主程序添加注解 `@EnableTurbine`

聚合后的监控数据路径：

[http://localhost:6001/turbine.stream][http_localhost_6001_turbine.stream]

## 1.1 新建项目 ##

## 1.2 application.yml ##

spring:
      application:
        name: turbin
    
    server:
      port: 6001
    
    eureka:
      client:
        service-url:
          defaultZone: http://eureka1:2001/eureka, http://eureka2:2002/eureka
    
    turbine:
      app-config: order-service
      cluster-name-expression: new String("default")

## 1.4 主程序添加依赖 ##

package cn.tedu.sp10;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.cloud.netflix.turbine.EnableTurbine;
    
    @EnableTurbine
    @EnableDiscoveryClient
    @SpringBootApplication
    public class Sp10TurbineApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(Sp10TurbineApplication.class, args);
        }
    }

## 访问测试 ##

*  8201服务器产生监控数据:  
    [http://localhost:8201/abc123][http_localhost_8201_abc123]  
    [http://localhost:8201/][http_localhost_8201]
 *  8202服务器产生监控数据:  
    [http://localhost:8202/abc123][http_localhost_8202_abc123]  
    [http://localhost:8202/][http_localhost_8202]
 *  turbine 监控路径  
    [http://localhost:6001/turbine.stream][http_localhost_6001_turbine.stream]
 *  在 hystrix dashboard 中填入turbine 监控路径，开启监控  
    [http://localhost:4001/hystrix][http_localhost_4001_hystrix]
 *  turbine聚合了order-service两台服务器的hystrix监控信息
