Dear Sir/Mad,   

    I am confused by a strange Httperf output as following:


[wyy79@qoserver bin]$ httperf --hog --port 80 --failure-status 503  --rate 1 --server 166.111.70.100 --timeout 5 --uri /cgi-bin/test.pl --wsess 2,2,1 --burst-len 1   --session-cookies
httperf --hog --timeout=5 --client=0/1 --server=166.111.70.100 --port=80 --uri=/cgi-bin/test.pl --failure-status=503 --rate=1 --send-buffer=4096 --recv-buffer=16384 --session-cookies --wsess=2,2,1.000

I have two questions:
1. I think the number of  requests is 2*2( --wsess 2,2,1). Why in the output do it say 6 (requests 6)?
2. In the output, I cann't know how many sessions is sussessful. In the fact, all sessions are failed(5**=4).

  I will be appreciated if you can help me!!! Thank you!!

Sincerely,



Weiyaya
