Network traffic analysis with MRTG on Linkstation

This article describes the setup of mrtg http://people.ee.ethz.ch/~oetiker/webtools/mrtg/
It is assumed you do this on a debianized linkstation.

=== Ensure you have mrtg and snmpd (If you do not have them:) ===

apt-get install snmpd 
apt-get install mrtg 

=== Setup snmpd ===

Move the original /etc/snmp/snmpd.conf to a save place, e.g.

mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.original 

Create a new snmpd.conf with the following content:

(This example creates a community named "test" for the SNMP Daemon)
com2sec local localhost test 
group MyROGroup v1 local 
group MyROGroup v2c local 
group MyROGroup usm local 
view all included .1 80 
access MyROGroup "" any noauth exact all none none 

Restart the snmpd daemon
/etc/init.d/snmpd restart 

=== Setup mrtg ===

cfgmaker --global 'WorkDir: /var/www/apache2-default/mrtg/' --global 'Options[_]: bits,growright' --output /root/mrtg.cfg test@localhost 

This will setup mrtg. The html files will be created in the directory /var/www/apache2-default/mrtg/. The config file for mrtg will be stored in the directory /root and is named as mrtg.conf

=== Start mrtg ===

/usr/bin/mrtg /root/mrtg.cfg 

After the first & second start you will get messages like
Rateup WARNING: /usr/bin/rateup could not read the primary log file for localhost_2
Rateup WARNING: /usr/bin/rateup The backup log file for localhost_2 was invalid as well
Rateup WARNING: /usr/bin/rateup Can't remove localhost_2.old updating log file
Rateup WARNING: /usr/bin/rateup Can't rename localhost_2.log to localhost_2.old updating log file

The messages will disappear after the 3rd start

=== Automize the start ===
crontab -e 
insert the line
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/bin/mrtg /root/mrtg.cfg 
This will update your page every 5 Minutes

=== The results ===
You can see your networktraffic if you have a look on /var/www/apache2-default/mrtg/localhost_2.html (or similar)

=== More details ===
man mrtg 
man smnpd 
man snmpd.conf 
man crontab
