I dont see any stupidity in your question and on the urge to get to know something new.
you can refer this link for getting the configuration done for logging.

Before posting any query i would also suggest to do a search around here in Netpro (forum) to check out whether the same kinda query has been posted and solved.That will ofcourse help u to save time involved in posting and geting the replies from netpros here :-).
