$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:60:97:D1:69:B1
          inet addr:10.1.1.102  Bcast:10.1.1.255  Mask:255.255.255.0
          inet6 addr: fe80::260:97ff:fed1:69b1/10 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:9363754 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8015373 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:1525349627 (1454.6 Mb)  TX bytes:1507412321 (1437.5 Mb)
          Interrupt:10 Base address:0xd400

Those are 'packet' numbers, so I'm not sure they correspond to bytes or
anything.

mrtg should be able to map stuff for you, but it only takes snapshots of
current bandwidth use rather than total number of bytes moved.

Using SNMP you can grab counters that show how much traffic has been moved.

There are probably other ways to get that info.
