ARGUS Binary Size

Mon Sep 15 16:01:45 EDT 2014

Hey James,
The src and dst labels for traffic in argus records does not
equate to the number of packets we receive on the 2 DAG interfaces.
These src and dst are flow src and dst, and refer to the flow
source (the initiator of the flow transaction) and flow destination
(the target of the flow transaction).

I suspect that if there is a problem, its that argus is getting
packets from only one interface.
