Err... what's SNMP? (sorry, dumb question)

Simple Network Management Protocol. It is a way to gather statistics
from networked devices, like the number of bytes in and out of a
network interface.
OS X has some command-line SNMP tools, like snmpget and snmpwalk.

Alternatively get a router that reports to a syslog server. (You can run
syslog on a Mac, can't you?)

What would you be expecting the router to log? You'll probably find
your OS X box is already running syslogd.

This will depend on the router, but typically up/download speed, SNR margin,
and line attenuation; these every few minutes. I wil probably also log
details of outgoing traffic - so you need to be prepared to filter the log
file.

About the only thing mine (a Linksys running Tomato firmware - some
kind of mutant Linux) logs after it boots are DHCP requests and acks.
OTOH it records bandwidth usage quite handily anyway without using
syslog or SNMP :-)

Vigor routers give useful information ...
