[NTLUG:Discuss] Service Watchdog Script

[CoryC]

Does anybody have an example of a service watchdog script that they are willing to share? All of the examples I'm finding on the Internet only work if the service uses a port but not all of the services I want to monitor use a port (Snort, arpwatch, etc.). I'd like for it to be able to e-mail me when one of those services are down and possibly even try to restart it. I'm using CentOS 5.3.

Thanks,

Cory
