I was going to write a script to collect and report numbers of TCP
packet retransmissions. But when I look at the 'trends' for this host, I
see there is already a chart for "TCP/IP statistics" which includes
"In/Out/Retrans" - snip -
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.
