SpringCloud之HystrixDashBoard豪猪（七）

简介

　　除了隔离依赖服务的调用意外，Hystrix还提供了准实时的调用健康（HystrixDashBoard），Hystrix会持续的记录所有通过Hystrix发起的请求的执行信息，并以统计报表和图形的形式展示给用户，包括每秒执行多少请求多少成功，多少失败等；

　　Netflix通过hystrix-metrics-event-stream项目实现了对以上指标的监控,springcloud也提供了HystrixDashBoard的整合,对监控内容转化成可视化界面。

环境搭建

新建工程springcloud-consumer-hystrix-dashboard

① 导入pom依赖
