Spring Cloud Netflix 之 Hystrix Dashboard仪表盘监控

一、Hystrix Dashboard

Hystrix 仪表盘（Hystrix Dashboard）是Spring Cloud的仪表盘组件，可以查看Hystrix实例的执行情况，支持查看单个实例和查看集群实例，但是需要结合spring-boot-actuator一起使用。

Hystrix Dashboard主要用来实时监控Hystrix的各项指标信息。Hystrix Dashboard可以有效地反映出每个Hystrix实例的运行情况，帮助我们快速发现系统中的问题，从而采取对应措施

1、 新建一个springbootModule（springcloud-6-service-eureka-hystrix-dashboard），设置父项目；

2、 添加spring-cloud-starter-hystrix-dashboard等依赖；

<!-- spring-cloud-starter-netflix-hystrix-dashboard -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>

<!--继承统一的父项目-->

        <groupId>com.company</groupId>
