For monitoring, I would say something like Cacti, Ganglia or Munin. And for alerts, I would use Nagios.

For spot monitoring, ntop is useful for a quick graphical overview. One could always use netstat or tcpdump if you are into the command line stuff.

do any of these use the .NET stack so we don't need to install other languages? – Pure.Krome Apr 30 '09 at 8:22

Cacti (often) collects data via SNMP, so you could set up Cacti running in a VM monitoring your servers. – Tom Ritter Apr 30 '09 at 13:59
Even MRTG works fine. Have a try. – Caterpillar Jun 4 '09 at 11:07
