除了隔离依赖服务的调用以外，Hystrix还提供了准实时的监控（Hystrix Dashboard）Hystrix会持续记录所有通过Hystrix发起的请求的执行信息并以统计报表和图形的形式展示给用户，包括每秒执行多少请求多少成功，多少失败等，Netflix通过一个项目实现监控，springcloud也提供了Hystrix Dashboard 的整合，对监控内容转化成可视化界面

创建一个 Dashboard 的项目、

  port: 8086

启动类

@EnableHystrixDashboard 开启dashboard

package com.xxx;

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.zuul.filters.discovery.PatternServiceRouteMapper;

@SpringBootApplication
@EnableHystrixDashboard
public class UserDashboardApp {

  public static void main(String[] args) {

	  SpringApplication.run(UserDashboardApp.class, args);
	  
}
	
}
