Accessing whispers with bots

Other question then. Im logging every line in the socket just for debugging purposes, so if I get a whisper, shouldnt there also be something logged in the socket? Normally if somebody sends a message in a specific channel or the servers send PING it gets logged in there, so why arent whispers getting logged? Is that my problem? This is what I mean, why isnt there something similar with whispers:
