Ohhh. I think I see. It probably _is_ lining up with the numbers being 
reported by nstat. The difficulty is the number is being graphed as 
packets/second and plotted on the same chart as IN and OUT packets (also 
being graphed in packets/second). My small number of retransmissions is 
being lost in the noise of the total volume of packets.

Is there a way to re-define the graph to display a multiple of the 
recorded value? Or plot this counter against an alternate y-axis set to 
a different scale?

I suppose I could define a new graph to contain only retransmissions so 
the small number isn't swamped by the general traffic count.
