MRTG config info

Since I have been struggling to figure this out, I thought I would share my mrtg.cfg file set up to monitor eth0 on our ReadyNAS NV+:

### Global Config Options
#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

EnableIPv6: no
LoadMIBs: /home/username/www/mrtg/INFRANT.MIB
WorkDir: /home/username/www/mrtg

I couple of FYIs here:
The MIB might not even be necessary for the network statistics, but you can download it from the Infrant website here:
http://www.infrant.com/download/INFRANT-MIB.txt

This was on a NetBSD box, so your path to the username directory may look different (or wherever you decide to put it). You'll have to fill in the correct path/username. The IP address will be different as well.

That all being posted... does anyone know how to set up a config to show the volume statistics? (used, free, total)

Thanks!
