This is the script I use. The snmp collection is
Utilization percentages for two of our 3Com switches. They
are collected every 10 minutes ( tail n -143 gives last 24
hours).
It runs as a cron job at midnight every night. The printer
is a HP5SI postscript.
The sed statements toward the bottom of each case statement
are to insert the attached device, date, and file to plot
in the script that gnuplot uses (intest.plot).
# Utilization.scr

DT=`date +"%m-%d-%y"`

This is the gnuplot script. I set the terminal type to
postscript because of the printer. There several terminal
types available in gnuplot that output in formats that be
converted using netpbm or other utilities if you want a
different graphical output (GIF, etc.). There also several
options that will change the graphing formats. Check the
online help and man pages.
