Really good point.

If you want to check the accuracy of the reports (this is a router, right?),
you want to report all of the traffic on all of the interfaces.

The sum of all of the "in"'s should be about equal to the sum of all if
the "out"'s (assuming overhead, retransmissions, and traffic terminating
_on_ the router a low enough to ignore).
