Analyze Network events with xperf

I have written a small tcp-client/server-thing for testing the xperf-networkttrace capabilities. But as it seems I did do something wrong with xperf. When I use the Xperf kernel group NETWORK or DIAG+NETWORKTRACE it just shows me the "casual" stuff and nothin about tcp/udp-reads and writes...

Anyone got an clue of how to get these information from xperf?开发者_Go百科 (did not find anything really helpful via google)

I found out, that the send and receive-actions are logged under the "Generic Events" section, as marks.

You can also find them "easily" if You post-process the etl-log into a human readable file and search for TCPRead/Write UDPRead/Write TCPDisconnect/Connect/Accept etc...
