Subject: [Wireshark-users] Tshark statistics problem

 

Hi,

 

Does some one know why the following command: “Tshark.exe –r testfile.pcap –q –z io,stat,30,COUNT(tcp.analysis.retransmission) tcp.analysis.retransmission” outputs this:

 

C:\Program Files\Wireshark>tshark.exe -r update.pcap -q -z io,stat,30,COUNT(tcp.

analysis.retransmission)cp.analysis.retransmission

420.000-450.000       2       314

450.000-480.000     163     47626

 

Instead of a column with the counted tcp retransmissions?

 

Got the same result with :

tshark.exe –r testfile.pcap” –q –z io,stat,30,”COUNT(tcp.analysis.retranmission)tcp.analysis.retransmission”,”AVG(tcp.window_size)tcp.window_size”,”MAX(tcp.window_size)”,”MIN(tcp.window_size)tcp.window_size”


I am using TShark 1.1.3 (SVN Rev 27807) .

(testfile.pcap does contain tcp and retransmission so its not that)

 

Kind regards,

                    Jo
