Issue about client-server logs

[shuqilou]

When a connection is established between the client and the server，will the server record logs? I believe that the source code contains the logic but I didn't find it.

Yes, but it will only log when --debug is enabled:
https://github.com/coreos/etcd/blob/master/etcdserver/api/v2http/client.go#L133

No audit logging, just debug logging as @heyitsanthony pointed out. If you want to see audit logging, comment at #5019. Thanks.
