</project>

配置

server:
  port: 4500

启动类

package jiangbo.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

@SpringBootApplication
@EnableHystrixDashboard
public class JiangBoApplication {

    public static void main(String[] args) {

        SpringApplication.run(JiangBoApplication.class, args);
    }
}

验证

打开主页

访问 http://localhost:4500/hystrix ，打开 Hystrix Dashboard。

填写信息

第一行填写之前暴露的监控数据接口：http://localhost:4410/hystrix.stream

delay 可以默认，title可以自定义，这里填写 order，点击 Monitor Stream ，就可以开始监控了，多次访问 http://localhost:4410/order/payment 看看监控面板的变化。
