2. Create the initial config file and poll a device

sudo cfgmaker  --output /home/mrtg/mrtg.cfg ciscodisco@10.0.0.21

For more information see cfgmaker

3. Either create additional cfg files for other devices, and copy/paste the relevant parts to the mrtg.cfg file or add them manually

4. Start MRTG

$ sudo env LANG=C /usr/bin/mrtg /home/mrtg/mrtg.cfg

5. Make MRTG run every 5 minutes

$sudo crontab  -e

#        m      h       dom     mon     dow     command
         */5      *       *       *       *       env LANG=C /usr/bin/mrtg /home/mrtg/mrtg.cfg  --logging /var/log/mrtg/mrtg.log

Make apache run perl script

This will install perl module in apache

$ aptitude install libapache2-mod-perl2

This addition in /etc/apache2/apache2.conf configuration file will allow cgi and perl script to be run in every directory, not just cgi-bin/.

AddHandler cgi-script .cgi .pl

<Files ~ "\.pl$">
Options +ExecCGI
