Capture the traffic of your application, and then look in the packet 
detail pane. The first line says "Frame 1", and expanding it shows you 
the "Packet Length" field, in bytes.

If you want to graph these, go to Statistics -> I/O graphs.
Change "Y Axis Unit" to "Advanced" and then enter 
"frame.pkt_len" (without the quotes) for the quantity to measure in the 
first graph.
