I'm looking for a FREE Log Monitoring software. Something that will montior the logs of my 40 some servers and email me say if someone trys to access an account 5 times and fails. Or critical errors.. All that type of stuff.

I have googled it and I only found either software that you had to load on every server(not bad but cost to much) or software that you don't have to load but cost to much. I'm looking for something FREE... LOL...

Let me know if anyone knows of anything good. If not than if you know of something that is very very very cheap and does the same thing. I would appreciate that too.
