Not a stupid question at all. I am assuming you already know how to create an event set. When you add an event to an event set, there is a box to the left that you check to ignore that event. I created 3 different ignore lists for the 3 different logs and named them appropriately. Once you have your event set created with all the events you want to ignore, just apply it to the machines as you would any other event set. Let me know if I am on line with what you are asking.
