OT: Recommendations for system monitoring tool

[John Heim]

I am thinking of setting up a network monitoring  tool. My needs are fairly 
simple, I just want to be alerted somehow if the temperature on our file 
server gets too high. That's the minimum. I'm sure I could think of other 
things to do eventually.

But I don't want to have to run X to access the  setup or the monitoring 
interface. I would prefer a command line interface.

Anybody have any experience with that? Doing an apt-cache search leads me to 
nagios and  spong. But I would like to know if either is preferable if 
you're working from the command line.
