Unable to connect to Command Metric Stream 这个是错误是链接不上,错误原因可能是缺少jar包或者没有Enable相关服务。
针对ribbon实现断路由监控
1.则pom中需要加入以下jar包
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId> </dependency>2.boot启动程序启动下面标签对应的服务
3.对应的service上肯定要加上断路由设定的
针对fegin的实现断路由监控
因为fegin中本身自带断路器的,所以跟ribbon的处理稍有不同
1.则pom中需要加入以下jar包,本身实现断路处理不需要引入spring-cloud-starter-hystrix这个jar就可以实现,但是要加入监控则还是需要引入下面3个jar包
2.boot启动程序启动下面标签对应的服务(一定不能少@EnableCircuitBreaker,刚开始就是少这个报的unable to connect错误)
3.对应的service上肯定要加上断路由设定的

@HystrixCommand(fallbackMethod = "hiError")
