简介
Hystrix集群监控使用的是turbine,而turbine是基于Dashboard的
组建Hystrix集群
新建一个Module,该Module为Maven项目,命名为:microservice-student-provider-hystrix-1005,把microservice-student-provider-hystrix-1004的所有文件都复制一份过来,修改几个地方:
修改application.yml
server.port修改为:1005,eureka.instance.instance-id: microservice-student-hystrix修改为:1005
修改启动类
如果启动类是复制过来的,重命名为:StudentProviderHystrixApplication_1005
新建集群监控项目
新建一个Module,命名为:microservice-student-consumer-hystrix-turbine-91

测试
启动以下项目
microservice-eureka-server-2001
microservice-eureka-server-2002
microservice-eureka-server-2003
microservice-student-provider-hystrix-1004
microservice-student-provider-hystrix-1005
microservice-student-consumer-80
microservice-student-consumer-hystrix-dashboard-90
microservice-student-consumer-hystrix-turbine-91
调用服务集群
浏览器地址栏输入:http://localhost/student/getInfo
监控数据
浏览器地址栏输入:http://localhost:91/turbine.stream
如果使用图形界面监控,则先输入:http://localhost:90/hystrix 打开图形监控界面,在第一个输入框输入:http://localhost:91/turbine.stream ,再点击按钮即可
