How to create my Windows Log Notification System

I am really interested in creating my own personalized Windows Event Log Notification System. I read about that in a forum in a website and all I can see is, of how happy they are about it. But it does not say on the forum, how to do that.
I tried asking how to create and personalize a Log Notification System but I could not find the right answers. All the steps they posted did not work.
I hope someone here can give me a proper walk through. I would really appreciate it.
