Create MRTG index file:
$ sudo indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html
Execute MRTG:
$ env LANG=C /usr/bin/mrtg /etc/mrtg.cfg
MRTG will default graph the data every 5 minutes.
To change this interval into 10 minutes, add this line into mrtg.cfg:
Interval : 10
To view MRTG graphs, go to http://localhost/mrtg/
