I am not sure if the original posts have been removed but the question:-
and it is legal to log all this?
Very much depends on the country you are in. In Scandinavia it is illegal to log legitimate information. That is if some one is entitled to enter and they enter with the correct code you can't log it. In other countries like the U.K. you can do things like this. You would have to ask an expert in the country you are in for a proper answer.
Polite request.
Can you post code between the square brackets that come up when you click the hash icon in the reply box.
