Hi, I would like to know, if anyone know a program that could monitor my servers: oracle database, dns, pop, smtp, http, etc. So if any of this services goes down, it could send out a beeper or an e-mail.
An example of this is Servers Alive
http://www.woodstone.nu/salive/
but it works under windows
So I need something like this but it has to run under Linux completly.
