-# mrtgext.pl v0.3
-# (c)2000 Cliff Woolley, Washington and Lee University
-# jwoolley@wlu.edu
-#
-# A UNIX counterpart to Jim Drews' MRTG Extension for netware servers
-# Mimics output of mrtgext.nlm using output of various standard UNIX
-# programs (df, uptime, and uname)
-#
-# Dependencies: I make some assumptions about the output format of
-# your df and uptime commands. If you have nonstandard outputs for
-# any of these, either pick a different command that gives more
-# standard output or modify the script below. Example: use /usr/bin/bdf
-# on HP-UX instead of /usr/bin/df, because bdf follows the output format
-# I expect while df does not. This was written on Linux and tested on
-# HP-UX 10.20 (with changes to the subroutines at the bottom of the
-# program to reflect HP's command parameters); similar tweaking could
-# well be required to port this to other platforms. If you get it
-# working on your platform, please send me any changes you had to
-# make so I can try to incorporate them.
-#
-#
-# Following is what I expect the programs' outputs to look like:
-#
-# ======= df ========
-# Filesystem 1k-blocks Used Available Use% Mounted on
-# /dev/sda1 1014696 352708 609612 37% /
-# /dev/sda2 2262544 586712 1559048 27% /apps
-# /dev/sda3 4062912 566544 3286604 15% /share
-# /dev/sr0 651758 651758 0 100% /cdrom
-# ===================
-#
-# ===== uptime ======
-# 3:17pm up 15 days, 4:40, 5 users, load average: 0.12, 0.26, 0.33
