Hystrix-Dashboard介绍

• 实时监控Hystrix的各项指标信息
• 是Hystrix的仪表盘组件
• 可以快速发现系统中存在的问题
• 通过实时监控来动态修改配置，直到满意为止
• 总而言之：就是页面监控工具

案例

microservicecloud-consumer-hystrix-dashboard-9001

@SpringBootApplication
//开启HystrixDashboard
@EnableHystrixDashboard
public class DeptConsumer_DashBoard_App_9001
{
    public static void main(String[] args)
    {
        SpringApplication.run(DeptConsumer_DashBoard_App_9001.class, args);
    }
}

测试1-启动监控服务

如果如下面显示，表示监控程序启动成功。

http://localhost:9001/hystrix

测试2-启动监控服务+被监控的服务+3个eureka

microservicecloud-consumer-hystrix-dashboard-9001

microservicecloud-provider-dept-hystrix-8001

   microservicecloud-provider-dept-hystrix-8001的POM
