:)  The word "monitoring" has many definitions in computer-ese.  It goes
all the way from simple ping-tests to service availability to full
content-based censorship.

FreeBSD makes an excellent platform for monitoring/data collection and
presentation.

If you wanted to look at usage patterns, then FreeBSD hosting a MRTG data
collector would be good.  MRTG uses SMNP to query routers about traffic
seen and generates graphs based on the collected data.  It's pretty neat.
We have it running here at the University and the usage patters we see out
of the residence halls is, well, revealing.  

If you want to dig deeper, you'll want to run a proxy server, like squid,
fwtk, or socks.
