    I'm using the modified gawk (Gnu awk) that is part of the ISODE 6.0 dis-
tribution.  I collect ifInOctets, ifOutOctets, and sysUpTime every 2 minutes.
I then munge the data to get a data rate and write it to a file.  Then, I use
another gawk script to separate the input and output data into several temp
files that are feed to xgnuplot for display on a workstation running X.  This 
shows the peaks nicely, complete with time of day.  We have a 14.4k baud link
that I've been monitoring, and the graphs regularly flatten out at 14.4k baud.
We are now planning to upgrade the link to 56kb.  Graphs alway help to impress
the management :-).
