Turbine Aggregation Monitoring

一、搭建监控模块

1. Create the monitoring module

创建hystrix-monitor模块,使用TurbinePolymerization monitoring multipleHystrix dashboard功能,

2. 引入TurbinePolymerization started monitoring rely on

            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
​
​
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>
​
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
​
</project>

3. 修改application.yml

spring:
  application.name: hystrix-monitor
server:
  port: 8769
turbine:
  combine-host-port: true
  # Configuration of the need to monitor the service name list
  app-config: hystrix-provider,hystrix-consumer
  cluster-name-expression: "'default'"
  aggregator:
    cluster-config: default
  #instanceUrlSuffix: /actuator/hystrix.stream
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
​

4. 创建启动类

@SpringBootApplication
@EnableEurekaClient
​
@EnableTurbine //开启Turbine Very polymerization monitoring function
@EnableHystrixDashboard //开启HystrixThe dashboard monitoring function
public class HystrixMonitorApp {
    
​
    public static void main(String[] args) {
    
        SpringApplication.run(HystrixMonitorApp.class, args);
    }
​
}

​

二、修改被监控模块

需要分别修改 hystrix-provider 和 hystrix-consumer 模块：

1、导入依赖：

      <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
​
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>

2、配置Bean

此处为了方便,Be configured at startup class.

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

3、启动类上添加注解@EnableHystrixDashboard

​

@EnableDiscoveryClient
@EnableEurekaClient
@SpringBootApplication
@EnableFeignClients 
@EnableHystrixDashboard // 开启HystrixThe dashboard monitoring function
public class ConsumerApp {
    
​
​
    public static void main(String[] args) {
    
        SpringApplication.run(ConsumerApp.class,args);
    }
    @Bean
    public ServletRegistrationBean getServlet() {
    
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }
}

​

三、启动测试

1、启动服务：

eureka-server
hystrix-provider
hystrix-consumer
hystrix-monitor

2、访问：

在浏览器访问http://localhost:8769/hystrix/ 进入Hystrix Dashboard界面

Enter the monitoring interface ofUrl地址 http://localhost:8769/turbine.stream,监控时间间隔2000毫秒和title,如下图

实心圆：It has a color or size,Represent the instance of the monitoring level and the flow.如上图所示,它的健康度从绿色、黄色、橙色、红色递减.Through the solid circle show,我们就可以在大量的实例中快速的发现故障实例和高压力实例.
曲线：用来记录 2 分钟内流量的相对变化,我们可以通过它来观察到流量的上升和下降趋势.
