Make mrtg create a new report every 5 minutes by adding the following line in crontab (type crontab -e):

0,5,10,15,20,25,30,35,40,45,50,55 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg.cfg


Create a summary page showing all graphs:

indexmaker /etc/mrtg.cfg > /var/www/mrtg/index.html


If using the default mrtg/apache configuration you can access the graphs here: http://yourserver/mrtg
