your MRTG file is empty - verify your mrtg config - I noticed you have another thread indicating an SNMP issue - they're maybe related.

Let's also check your RRD files for MRTG. Not entirely certain how you installed MRTG on your system, but on mine they are located under /var/lib/mrtg - run ls -l against them.

For good measure, let's also see what MRTG says about your configs. Same deal, not sure where your binaries and whatnot ended up, but on my system that would be:

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

If it returns no output, that's a good thing. Otherwise, post back whatever it spits out.
