What happens when the OLAP Query Log doesn't turn on

Bill Anton recently had a really great post about the OLAP query log and how to turn it on and translate it into English (available here). I've been meaning to blog about this for awhile but have been putting it off, and reading his post motivated me to go actually do it, instead of just staring at the note I have sketched down (thanks Bill!) One thing to keep in mind is that the query log does consume I/O while in use, so be careful about putting too much overhead on your server.
