上一篇，我们讲了这个Hystrix 整合到项目中，Hystrix其实还提供了准时实时监控（Hystrix Dashboard），Hystrix会持续记录说有通过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hystrix-metrics-event-stream项目实现了对以上指标的监控。Spring Cloud也提供了Hystrix Dashboard的整合，对监控内容转化成可视化界面。

新建 pcloud-consumer-hystrix-dashboard9001

修改pom文件：

新增application.yml

server:
  port: 9001

新增主启动类：HystrixDashboardMain9001

package com.younger.springcloud;

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

@SpringBootApplication
@EnableHystrixDashboard
public class HystrixDashboardMain9001 {
    public static void main(String[] args) {
        SpringApplication.run(HystrixDashboardMain9001.class,args);
    }
}

所有Provider微服务提供类(8001/8002/8005)都需要监控依赖配置

<!-- actuator健康监控依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

测试验证：

启动9001

访问地址： http://localhost:9001/hystrix

spring 监控api时间 spring cloud监控_spring_04

修改 pcloud-provider-hystrix-user8005

spring 监控api时间 spring cloud监控_spring_05

@Bean
    public ServletRegistrationBean getServlet() {
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }

这个配置就是为了服务监控，这个是由于SpringCloud升级后的问题,需要新增这个配置。
