[Xymon] where does xymon client get tcp packet data?

[John Thurston]

The below relates to linux, xymon 4.3.17

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"   I'm specifically looking for TCP retransmission 
count. This counter does not seem to line up with information being 
reported by nstat.

What is this built-in test reporting, and from where is it collected?
