It should log the actual data sent from the server (not just a converted image, since having the raw data would make reimplementation by a private server more trivial, as long as the client is vanilla in accepting the data), and also RSCMinus should log the attempt given in out.bin.
To determine if the sleepword sent was successful or not, just look for a "You wake up refreshed" message. That will work even if the player is spamming the sleep function, or the player has 0 fatigue when starting the sleep.
