How often do you check over your server logs?

I think that the main concern is the cost. There are a bunch of things I'd like to do, but I always have to look at costs and make decisions. Server administration is certainly one of them. How much does it cost usually? Also how can I verify the validity of the server administration server? Suppose that I learn how to administer my server on my own. How difficult is it? How long does it take for me to learn basics? How much time should I spend every day to administer my server?
