本文介绍如何配置Hystrix-Dashboard及整合Turbine来实现跨服务的实时监控。通过实例展示了如何搭建一个能够查看多个服务状态的Hystrix-Dashboard界面。

Hystrix-dashboard是一款针对Hystrix进行实时监控的工具，通过Hystrix Dashboard我们可以在直观地看到各Hystrix Command的请求响应时间, 请求成功率等数据。但是只使用Hystrix Dashboard的话, 你只能看到单个应用内的服务信息, 这明显不够. 我们需要一个工具能让我们汇总系统内多个服务的数据并显示到Hystrix Dashboard上, 这个工具就是Turbine.

Hystrix Dashboard

新建一个工程命名为：mymicroservicecloud-consumer-hystrix-dashboard

2.服务启动类

package com.yxf.springcloud;

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

@SpringBootApplication
@EnableHystrixDashboard
public class DeptConsumer_DashBoard_App
{
	public static void main(String[] args)
	{
		SpringApplication.run(DeptConsumer_DashBoard_App.class, args);
	}
}

3.application.yml

server:
  port: 9001
