MRTG

From Fastsh.it

MRTG can be used to show alot of things, be it cpu temperature, network utilization or how many kilometers your hamster has run in its tiny wheel. This little tutorial will only explain how to make it show very simple graphs of network utilization.

First we install mrtg and mrtgutils

apt-get install mrtg mrtgutils

then we make the dirs

mkdir /var/www/mrtg

and then we edit or make the mrtg.cfg file

nano /etc/mrtg.cfg you can use vi if you want

in that we insert this bunch of text:

WriteExpires: Yes

workdir: /var/www/mrtg

forks: 2

refresh: 300

interval: 5

runasdaemon: yes

Target[index]: `/usr/bin/mrtg-ip-acct eth0`

XSize[index]: 600

YSize[index]: 180

MaxBytes[index]: 1310720

Title[index]: my.server.name: eth0

PageTop[index]: Traffic Analysis for my.server.name

WithPeak[index]: w

Options[index]: growright, bits

then we start mrtg with this line

evn LANG=C /usr/bin/mrtg /etc/mrtg.cfg

and voila, after about 5 minutes you will be able to goto your servers address, add /mrtg and watch stats being collected ;)
