[Click] TCPCollector

[Bjørn J. Villa]

Hi,

 

Reading the Element description for TCPCollector I was expecting to see the
TCP window size reported per flow in the xml file, but this is not the case.
At least if I am not doing something completely wrong
.

 

Click instructions:

 

   -> a :: AggregateIPFlows

   -> TCPCollector(bv_tcpinfo.xml,WINDOWPROBE true, INTERARRIVAL true)

 

Click xml sample output:

 

Why is the window size not being reported ? Did I misunderstand the element
description ?

 

  <?xml version="1.0" standalone="yes" ?>
