**springcloud  Hystrix Dashboard微服务监控简介**

## Hystrix监控 ##

除了隔离依赖服务的调用以外，Hystrix还提供了近实时的监控，Hystrix会实时、累加地记录所有关于HystrixCommand的执行信息，包括每秒执行多少请求多少成功，多少失败等。Netflix通过hystrix-metrics-event-stream项目实现了对以上指标的监控。springcloud也对Hystrix dashboard的整合，对监控内容转化成可视化的界面

**springcloud  Hystrix Dashboard微服务监控实战**

1，新建微服务监控工程microservicecloud-consumer-hystrix-dashboard

2，pom文件引入微服务监控jar包

pom文件需要的jar

            </dependency>
        </dependencies>
    
    </project>

3，修改启动类添加@EnableHystrixDashboard注解开启微服务监控

package com.atguigu.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);
    	}
    }

4，编写yml文件设置内置tomcat端口

5，所有的provider微服务提供者(8001/8002/8003)都需要监控依赖配置

pom文件添加

6，启动相关的微服务

6.1启动microservicecloud-consumer-hystrix-dashboard微服务监控

微服务监控成功启动可以看到如下：[http://localhost:9001/hystrix][http_localhost_9001_hystrix]

6.2启动3个eureka集群

6.3启动microservicecloud-provider-dept-hystrix-8001

整除访问监控数据：[http://localhost:8001/hystrix.stream][http_localhost_8001_hystrix.stream]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l3bDQ3MDgxMjA4Nw_size_16_color_FFFFFF_t_70 4][]

通过这样的方式估计你也看不明白，这是一堆json串解析也不方便，我们希望有更好的办法直观的视图显示

别急我们前面就提到过springcloud也对Hystrix dashboard的整合，对监控内容转化成可视化的界面，下面我们就看看怎么玩吧

如何查看监控指标？

刷新之后圈圈变大了，一线也升高了（调用的频次     绿色0升到大14）流量压力
