# This will look at the $trafficDir directory for MRTG generated HTML
# files, parse them and generate a listing of the most active interfaces
# in a file called "active.htlm" in the same directory
#
# modify this if you wish as long as the above credit is not removed
#
# The only weird thing I do is to skip tunnel interfaces (see code below)
#
# TWO VARIABLES YOU MUST CHANGE
#
$trafficDir="/usr/local/httpd/htdocs";
#
# I put it in a file and include it because I use it in other scripts
# if you don't - comment this out and uncomment the above line
#require "trafficdir.include";
