1、在服務呼叫者（hystrix客戶端）的依賴檔案pom.xml加入檢測依賴

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

啟動專案訪問 http://127.0.0.1:8666/hystrix.stream 

2、建立一個springboot的檢測專案 eureka-hystrix-monitor

pom.xml

   <build>

            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
   </build>
</project>

啟動類EurekaHystrixMonitorApplication.java

@SpringBootApplication
@EnableHystrixDashboard // Hystrix 儀表板；/hystrix 檢視儀表盤；在hystrix客戶端應用使用/hystrix.stream監控
public class EurekaHystrixMonitorApplication {

   public static void main(String[] args) {
      SpringApplication.run(EurekaHystrixMonitorApplication.class, args);
}
}

新建application.yml設定下訪問埠

server:
  port: 8777

啟動專案 訪問http://127.0.0.1:8777/hystrix，填入被監控的服務地址，填寫title，點選Monitor Stream

呼叫服務介面http://127.0.0.1:8666/hello

我們再測試下斷路器的狀態，執行之前編寫main方法，請求hello介面20次

斷路器的狀態成功監控
