SpringCloud个人笔记-07-Hystrix-Dashboard初体验

 

• sb-cloud-hystrix-dashboard

 

Hystrix Dashboard，它主要用来实时监控Hystrix的各项指标信息。通过Hystrix Dashboard反馈的实时信息，可以帮助我们快速发现系统中存在的问题

但是只使用Hystrix Dashboard的话, 你只能看到单个应用内的服务信息, 这明显不够. 我们需要一个工具能让我们汇总系统内多个服务的数据并显示到Hystrix Dashboard上, 这个工具就是Turbine

    #注册时使用ip而不是主机名
    #prefer-ip-address: true
    #指定ip
    #ip-address: ip

@SpringBootApplication
@EnableHystrixDashboard //启用HystrixDashboard
public class SbCloudHystrixDashboardApplication {

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

}

 

访问 http://localhost:9007/hystrix

 

　　监控之前的 sb-cloud-hystrix项目，单实例情况下访问 http://hystrix-app:port/hystrix.stream

　　但是得在 sb-cloud-hystrix项目中要添加依赖。

　　添加actuator依赖后访问 http://localhost:9006/hystrix.stream 出现ping 即可

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

 

 

最终测试结果如下:
