Watching processes?

[Gilles Ganault <gilles.ganault@...>]

Hello

	I need to investigate why an application stops running on a Linux
appliance.

I was thinking of writing a small Lua script that would be ran every
minute by Cron to parse the output of "ps aux" and send an e-mail in
case the application is no longer listed.

Is this a good way to do what I need, or are there better, ready-made
ways to do this?

Thank you.
