Do snmpwalk on 1.3.6.1.2.1, if this doesn't return much data then
there's something wrong with you ACL.

/proc/net/dev gives you packet and byte counters per interface.
Something like  awk -F'[: ]*' '/eth0/{print $3"\n"$11}' < /proc/net/dev
will provide you with the byte counters. You can use this with the
external program interface (see faq.mrtg.org).

I guess you need to modify your ACL ("view" in /etc/snmpd.conf)
and everything will be OK.
