But is it necessary to monitor all of it? I mean, just because you can 
monitor something doesn't necessarily mean that it's useful to do so.

Put a couple of SCSI-disks in a RAID5 array and get as much RAM as you 
can lay your hands on. Have it run on a dual CPU system, severely 
stripped of everything unnecessary (i.e. don't use RedHat).

Openwall GNU/*/Linux (www.openwall.com) is a nice distro for this sort 
of thing. In default startup it runs about 12 processes. It uses RPM as 
package managing systems and keeps focus on security. The backside of it 
is that there aren't that many RPM's around. I've created a couple 
(about 40) of them that are necessary for running Nagios and compiling 
the plugins and that sort of thing. Let me know if you need them, and 
I'd be happy to provide some means of downloading them.
