Hystrix-Dashboard介紹

• 實時監控Hystrix的各項指標資訊
• 是Hystrix的儀表盤元件
• 可以快速發現系統中存在的問題
• 通過實時監控來動態修改配置，直到滿意為止
• 總而言之：就是頁面監控工具

案例

microservicecloud-consumer-hystrix-dashboard-9001

@SpringBootApplication
//開啟HystrixDashboard
@EnableHystrixDashboard

public class DeptConsumer_DashBoard_App_9001
{
    public static void main(String[] args)
    {
        SpringApplication.run(DeptConsumer_DashBoard_App_9001.class, args);
    }
}

測試1-啟動監控服務

如果如下面顯示，表示監控程式啟動成功。

http://localhost:9001/hystrix

測試2-啟動監控服務+被監控的服務+3個eureka

microservicecloud-consumer-hystrix-dashboard-9001

microservicecloud-provider-dept-hystrix-8001
