[GitHub] [incubator-brpc] FancyJan opened a new issue #1668: 希望在ChannelBalancer的Describe方法中有办法获取remote_side信息
FancyJan opened a new issue #1668:
URL: https://github.com/apache/incubator-brpc/issues/1668
**Is your feature request related to a problem? (你需要的功能是否与某个问题有关?)**
希望在组合channel的'ChannelBalancer::Describe'中有办法获取对应server_id的remote_side信息。
**Describe the solution you'd like (描述你期望的解决方法)**
https://github.com/apache/incubator-brpc/blob/master/src/brpc/selective_channel.cpp#L189
1. 如果add的channel只有一个固定节点的话，设置options的remote_side为这个单节点的remote_side。
2. （不必要）如果add的channel有多个节点的话，可能需要SocketOptions新增一个string字段初始化用的名字服务地址。
如果1，2满足的话，就有办法在'ChannelBalancer::Describe'中获取对应的remote_side并输出到os了。
**Describe alternatives you've considered (描述你想到的折衷方案)**
或者有办法通过subchannel的socketid知道对应的原始channel的socketid也可以。
例如subchannel的socketid=1，原始channel的socketid=0。如果知道这层关系，则可以通过sockets服务看到对应的remote_side。
**Additional context/screenshots (更多上下文/截图)**
还是上文提到的例子，subchannel的socketid=1，原始channel的socketid=0。
这是socketid=1的Socket信息，无法直接拿到remote_side。user中的SubChannel对应的Socket对象才能拿到remote_side。
