Nagios is a fantastic tool for monitoring machine states.  You can capture
and get reporting on almost anything regarding service states and
uptime/downtime, configure for SMS and email alerts, report on SNMP and WMI
data, etc

The project has recently been forked, and Icinga (http://icinga.org) is
looking very promising too.

We actively use Nagios and offer hosted instances for some of our clients -
our fully managed clients are monitored using Nagios by default.  That way
we usually know about issues before our clients do (low disk space on
servers, stopped services, loss of connectivity, etc).

I used to use OCS at my previous employer - again it's very feature rich and
works best in conjunction with GLPI as a ticketing system.  Great for
producing ad-hoc reports on hardware, checking specs, and installed software
and service pack versions without leaving your desk :) Definitely worth a

Oh and for nmap, to identify hardware/OS by vendor, the command would be

nmap -T4 -A

If it's a large subnet and you'd like greppable output it would be:

nmap -T4 -A -oG scan.txt

Hope this helps
