One of JPRS operators said that socket statistics is important because
DSC cannot offer socket statistics information.

Now, I'm reading current auth server code.

I found that

   src/lib/cc/session.cc:Session() calls asio directly.

   lib/util/io/socketsession.cc:SocketSessionForwarder::connectToReceiver()
    calls socket(),connect() system calls directly.

Then, at asiolink and asiodns level, we can count TCP/UDP only.
