SpringCloud警告(Eureka)：EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.

警告!Eureka可能存在维护了错误的实例列表(当它们没有启动的时候,Eureka却把它当成启动的了):Renews值小于Threshold值,因此剩下未过期的都是安全的. 原因分析: 这个是Eureka的自我保护机制.Eureka Server在运行期间,会统计心跳失败的比例在15分钟之内是否低于85%,如果出现低于的情况(在单机调试的时候很容易满足,实际在生产环境上通常是由于网络不稳定导致),Eureka Server会将当前的实例注册信息保护起来,同时提示这个警告. Eureka serv…

启动两个client,过了一会,停了其中一个,访问注册中心时,界面上显示了红色粗体警告信息: 查阅了很多资料,终于了解了中间的问题.现将理解整理如下: Eureka server和client之间每隔30秒会进行一次心跳通信,告诉server,client还活着.由此引出两个名词: Renews threshold:server期望在每分钟中收到的心跳次数 Renews (last min):上一分钟内收到的心跳次数. 前文说到禁止注册server自己为client,不管server是否禁止,阈…

Spring Cloud中五大神兽总结(Eureka/Ribbon/Feign/Hystrix/zuul)

Spring Cloud中五大神兽总结(Eureka/Ribbon/Feign/Hystrix/zuul) 1.Eureka Eureka是Netflix的一个子模块,也是核心模块之一.Eureka是一个基于REST的服务,用于定位服务,以实现云端中间层服务发现和故障转移.服务注册与发现对于微服务架构来说是非常重要的,有了服务发现与注册,只需要使用服务的标识符,就可以访问到服务,而不需要修改服务调用的配置文件了.功能类似于dubbo的注册中心,比如Zookeeper. Eureka包含两个组件:…
