SpringCloud系列十一：HystrixDashboard

除了隔离依赖服务的调用以外，Hystrix还提供了准实时的调用监控（Hystrix Dashboard），Hystrix会持续地记录所有通过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。  
1、新建microservicecloud-consumer-hystrix-dashboard工程  
2、引入依赖

<dependencies>
         <dependency>
             <groupId>com.atguigu.springcloud</groupId>
             <artifactId>microservicecloud-api</artifactId>
             <version>${project.version}</version>
         </dependency>
         <dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-web</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework</groupId>
             <artifactId>springloaded</artifactId>
         </dependency>
         <dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-devtools</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-eureka</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-config</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-ribbon</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-feign</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-hystrix</artifactId>
         </dependency>
         
         <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
         </dependency>
     </dependencies>

3、yml配置

server:
      port: 9003

4、在主启动类上添加注解@EnableHystrixDashboard

@SpringBootApplication
    @EnableHystrixDashboard   //开启HystrixDashboard服务调用监控
    public class DeptConsumerHystrixDashBoard_App {
        public static void main(String[] args) {
            SpringApplication.run(DeptConsumerHystrixDashBoard_App.class, args);
        }
    }

5、在所有Provider微服务提供者(8001、8002和8003)都需要添加actuator监控依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>

6、启动hystrix-dashboard工程。[http://localhost:9003/hystrix][http_localhost_9003_hystrix]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpemhpcWlhbmcxMjE3_size_16_color_FFFFFF_t_70]  
7、先启动3个eureka集群后，启动hystrix工程，重启hystrix-dashboard工程。  
 [http://localhost:8004/hystrix.stream][http_localhost_8004_hystrix.stream]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpemhpcWlhbmcxMjE3_size_16_color_FFFFFF_t_70 1]
