How to Perfect Install SNMP and MRTG in Fedora Core 4
A very good question that how would you monitor Utilization of your Server Interfaces. I quite often look for answers everytime I re-build my linux server and most of the times I find answers from following URLs.
General MRTG information from the homepage of MRTG.
Another useful resource for MRTG but may not have answers to your issues.
The Perfect solution I experienced every time I had to use it with Fedora or Redhat based systems. You may want to install snmpd and mrtg through YUM as suggested in above reply before you configure using following link.

I hope this helps.
