If you're talking about over time, I use MRTG now.  I also use The Dude 
(freeware) as a graphical pinger that does some snmp.

I'm unclear on how it would assist in the case of tracking down who or 
what is sucking up bandwidth at an unprecedented rate.  Last time things 
got sluggish I took a firewall dump, fed it into Wireshark and came up 
with the bandwidth-sucking IP's (yes, it's not fair, those Beyonce 
videos were job-related).

That's precisely the info I needed to hear, thanks.  It's pretty 
daunting (and flips my coworkers out) but I guess I have to sit down and 
really learn it.

Etherape is pretty cool too, especially when the boss is around. 
Nothing like blinky lights to get him going :)
