目前有需求，在客户端连接成功服务端后，主动推送客户端一些基本信息到服务端，所以需要应用层能感知建立连接或者重连事件通知，我看日志输出，断开和重连都会打印，跟踪了代码，并没有对应用层抛出事件通知，请问应用层如何去感知连接状态呢？

brpc对于底层连接的建立，释放，共享等对于应用层是屏蔽的，可能需要你自己在应用层做一些处理来感知。

@yongxiangzheng 还有一个比较tricky的方法，把你的要推送的信息作为Authentication信息，brpc在连接建立之后，第一个message会带上Authentication信息，服务端会调用VerifyCredential去验证，这个方法可以在连接建立的时候插入回调。接口在[这里](https://github.com/apache/incubator-brpc/blob/60159fc3f3e13490fb9806ea0a0cb0dcdbda7f7d/src/brpc/authenticator.h)，继承这个类之后，将对象插入到channel和server的options里。

现在采用定时调用checkhealth接口，进行判断连接状态，觉得这样做能感知连接状态，但是实时性不强，以及开启定时器会有一些额外性能开销。底层是为什么做这个屏蔽，是因为rpc调用规则吗
