iptables can be used. You can look at the count of packets/bytes that match
rules. This allows you to not count local traffic if needed. Where as looking
at the bytes sent out through a device would not (in cases where there
is a mix of local and remote destined traffic).

You can capture, save and reset the counts from time to time to protect against
losing them in a reboot or crash.
