What are the best event-data inputs for basic server & OS monitoring?

I want to implement the basic key searches defined in What are the best practice searches for Server & OS monitoring. There appears to be many potential inputs for data collection in the OS's add-ons. What are the necessary data inputs to make the basic key searches work correctly?
