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.

  • Cacti (often) collects data via SNMP, so you could set up Cacti running in a VM monitoring your servers.
