Hello, I am trying to understand the log file that we get from iperf because I need to parse the data and plot and I really need to know if I am doing it right. I want to understand how much thoughput arrive in every second. Imagine that you have the folowing log in the server side: ------------------------------------------------------------ Server listening on TCP port 6101 TCP window size: 64.0 KByte ------------------------------------------------------------ [1900] local 10.16.32.21 port 6101 connected with 10.16.32.111 port 52961 [1864] local 10.16.32.21 port 6101 connected with 10.16.32.111 port 52959 [1844] local 10.16.32.21 port 6101 connected with 10.16.32.111 port 52960 [ ID] Interval Transfer Bandwidth [1900] 0.0- 1.0 sec 0.00 Bytes 0.00 bits/sec [1900] 1.0- 2.0 sec 0.00 Bytes 0.00 bits/sec [1900] 2.0- 3.0 sec 7.91 KBytes 64.8 Kbits/sec [SUM] 0.0- 3.0 sec 7.91 KBytes 21.6 Kbits/sec [1864] 0.0- 1.0 sec 104 KBytes 849 Kbits/sec [1844] 0.0- 1.0 sec 105 KBytes 860 Kbits/sec [1900] 3.0- 4.0 sec 143 KBytes 1.18 Mbits/sec [SUM] 0.0- 4.0 sec 352 KBytes 721 Kbits/sec [1864] 1.0- 2.0 sec 155 KBytes 1.27 Mbits/sec [1844] 1.0- 2.0 sec 94.9 KBytes 778 Kbits/sec [1900] 4.0- 5.0 sec 112 KBytes 917 Kbits/sec [SUM] 1.0- 5.0 sec 362 KBytes 742 Kbits/sec [1900] 5.0- 6.0 sec 75.7 KBytes 620 Kbits/sec [1864] 2.0- 3.0 sec 90.3 KBytes 740 Kbits/sec [1844] 2.0- 3.0 sec 39.8 KBytes 326 Kbits/sec [SUM] 2.0- 6.0 sec 206 KBytes 422 Kbits/sec [1864] 3.0- 4.0 sec 155 KBytes 1.27 Mbits/sec [1900] 6.0- 7.0 sec 157 KBytes 1.28 Mbits/sec [1844] 3.0- 4.0 sec 70.4 KBytes 577 Kbits/sec [SUM] 3.0- 7.0 sec 383 KBytes 783 Kbits/sec Can I say that the throughput in every second is the sum of the one I get for each pair although they are print in the log after a while... 1 sec - TPT = 0 + 0.849 + 0.860 2 sec - TPT = 0 + 1.27 + 0.721 3 sec - TPT = 0.0216 + 1.18 + 1.27 .... If this is right and I can sum the different throughput values although they are print later in the log file, can someone help me to understand why they are printed later Best Regards, Marta _________________________________________________________________ Descubre todas las formas en que puedes estar en contacto con amigos y familiares. http://www.microsoft.com/windows/windowslive/default.aspx |
