Hystrix monitoring visualization page - Dashboard flow monitoring

1. What is Dashboard

Hystrix-dashboard is a tool page for real-time monitoring of Hystrix. Through Hystrix Dashboard, we can intuitively see the request response time and request success rate of each Hystrix Command.

 2. How to configure Dashboard - monitoring service

1. Import dependencies

<!--Hystrix依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix</artifactId>
    <version>1.4.6.RELEASE</version>
</dependency>
<!--dashboard依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
    <version>1.4.6.RELEASE</version>
</dependency>

2 configuration file configuration port number

server:
	prot: 8899   # 端口号可以自行配置  只要是和别的服务的端口号不冲突就好

3. Start the service------Dashboard exists as an independent service

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

3. Monitored service configuration

1. Add monitoring information dependency

添加监控注解
<!--actuator 完善监控信息 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

2. Add a servlet to the monitored service startup class

//增加一个Servlet
    @Bean
    public ServletRegistrationBean hystrixMetricsStreamServlet(){
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
        //参数固定写法
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        return registrationBean;
    }
