[Go] Identify dialed address and peer in client interceptors

[mkle...@gmail.com]

Hi all,

Is there a canonical way to retrieve information about the server that was dialed and called in a client interceptor?

UnaryClientInterceptor [0] seems to provide the ClientConn, on which ChannelzMetric [1] can be called to retrieve info that includes the dial target. But is that the best way?

I was not able to find a way to find the address of the actual server that ended up serving the request.

Thanks!
