Iperf CSV输出格式

字段是

时间戳，source_address，source_port，的destination_address，destination_port，间隔，transferred_bytes，bits_per_second

我通过观察推断出这一点

$ iperf -c localhost -r ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to localhost, TCP port 5001 TCP window size: 648 KByte (default) ------------------------------------------------------------ [ 5] local 127.0.0.1 port 54401 connected with 127.0.0.1 port 5001 [ 4] local 127.0.0.1 port 5001 connected with 127.0.0.1 port 54401 [ ID] Interval Transfer Bandwidth [ 5] 0.0-10.0 sec 50.3 GBytes 43.2 Gbits/sec [ 4] 0.0-10.0 sec 50.3 GBytes 43.2 Gbits/sec $ iperf -c localhost -r -y C 20140114124826,127.0.0.1,54402,127.0.0.1,5001,5,0.0-10.0,52551090176,42041052917 20140114124826,127.0.0.1,5001,127.0.0.1,54402,4,0.0-10.0,52551090200,41999020136 

编辑：你可以在这里find相关的源代码：

 // TCP Reporting printf( reportCSV_bw_format, timestamp, (stats->reserved_delay == NULL ? ",,," : stats->reserved_delay), stats->transferID, stats->startTime, stats->endTime, stats->TotalLen, speed); } else { // UDP Reporting printf( reportCSV_bw_jitter_loss_format, timestamp, (stats->reserved_delay == NULL ? ",,," : stats->reserved_delay), stats->transferID, stats->startTime, stats->endTime, stats->TotalLen, speed, stats->jitter*1000.0, stats->cntError, stats->cntDatagrams, (100.0 * stats->cntError) / stats->cntDatagrams, stats->cntOutofOrder ); } 

以“，”（逗号）作为字段分隔符来看第6个字段。 然后在这里看看这些行：

 Server listening on TCP port 5001 ------------------------------------------------------------ Client connecting to localhost, TCP port 5001 

[ 5] local 127.0.0.1 port 54401 connected with 127.0.0.1 port 5001 [ 4] local 127.0.0.1 port 5001 connected with 127.0.0.1 port 54401 [ ID] Interval Transfer Bandwidth [ 5] 0.0-10.0 sec 50.3 GBytes 43.2 Gbits/sec [ 4] 0.0-10.0 sec 50.3 GBytes 43.2 Gbits/sec

“5”表示客户端 – >服务器连接，然后“4”表示“服务器 – >客户端”连接（在“sciurus”给出的特定示例中查看源/目的端口。

date和时间，源IP，源端口，目标IP，目的端口，Iperf进程号，时间间隔，传输的数据量（字节），带宽（每秒位数），抖动（毫秒），丢失的数据报数量，总数发送的数据报，丢失的百分比，不按顺序接收的数据报的数量

我从以下获得了以上信息：

http://www.jb.man.ac.uk/~jcullen/code/python/iperf_tests.py

接受的答案跳过一个奇数字段：在源和目标IP +端口对之后的字段：

 timestamp, source_address, source_port, destination_address, destination_port, XXX, <---- this one interval, transferred_bytes, bits_per_second 

接受的答案中的代码表示这来自transferIDvariables。 这里的一些其他答案似乎认为它代表连接标识符或连接方向。 但是，通过代码的快速浏览表明transferID来自名为groupID的全局variables。 它被初始化为零：

 // Global ID that we increment to be used // as identifier for SUM reports int groupID = 0; 

然而，通过代码快速grep似乎表明，它是递增和递减很多，非常容易混淆。 似乎没有任何定义的常数说明它的含义。 手动testing（ iperf version 2.0.9 (9 Sept 2016) pthreads ）显示连接之间重复使用的数字。 所以我想这个故事的道德是…忽略这个数字？ 或者使用iperf3。

这里是一个简单的演示，使用CSV值并在循环中运行，检查是否满足给定的bps。

我还发现在上面的答案中有一个额外的字段，其值是3/4/5。 4和5似乎是方向。 3我不确定这是什么意思。 无论如何，如果这有助于：
