一、简介
Turbine是聚合服务器发送事件流数据的一个工具，Hystrix的监控中，只能监控单个节点，实际生产中都为集群，因此可以通过Turbine来监控集群下Hystrix的metrics情况
Turbine的github地址：https://github.com/Netflix/Turbine
二、基本环境
- 一个eureka模块
- 两个消费者模块
- 一个turbine监控模块
三、创建eureka模块
（1）创建项目
创建一个spring boot项目
（2）依赖

（4）启动类
package com.abc.consumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.EnableTurbine;
@SpringBootApplication
@EnableTurbine
@EnableHystrixDashboard
@EnableEurekaClient
public class MonitorApplication {
public static void main(String[] args) {
SpringApplication.run(MonitorApplication.class, args);
}
/*@Bean
public ServletRegistrationBean getServlet() {
HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
registrationBean.setLoadOnStartup(1);
registrationBean.addUrlMappings("/actuator/hystrix.stream);
registrationBean.setName("HystrixMetricsStreamServlet");
return registrationBean;
}*/
}
七、启动
（1）启动eureka模块
（2）启动两个消费者模块
（3）启动turbine监控模块
八、效果
（1）请求http://localhost:8080/consumer/depart/get/1
（1）请求http://localhost:8081/consumer/depart/get/1
浏览器访问http://localhost:9000/hystrix
输入http://localhost:9000/turbine.stream
