Do you already try:

 --output test.log

(in newer versions <code>--logfile</code>)

or using

blocks|key|5866702|text|我也遇到过这个问题。尽管手册页指定了"-o“或"--+output”将输出保存到文件中，但这实际上并不起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5866703|这似乎被标记为"WontFix"：https://code.google.com/p/iperf/issues/detail?id=24|offset|length|5866704|输出看起来像-o/-+|5866705|存在于以前的版本中，但不存在于当前版本中。在昨天的会议上达成的共识是，如果--+WontFix存在，那么我们应该修复它，否则人们应该使用shell重定向，我们将标记这个输出。所以，WontFix。|blockquote|5866706|5866707|5866708|所以可以按照Paolo建议使用typescript或">test.log“|5866709|entityMap|0|LINK|mutability|MUTABLE|url|https://code.google.com/p/iperf/issues/detail?id=24|1|https://stackoverflow.com/users/648682/paolo^0|0|H|1F|0|0|0|0|0|0|6|5|1|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Z|8|@]|9|@$D|10|E|11|1|12]]|A|$]]|$1|F|3|G|5|6|7|13|8|@]|9|@]|A|$]]|$1|H|3|I|5|J|7|14|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|15|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|16|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|17|8|@]|9|@$D|18|E|19|1|1A]]|A|$]]|$1|O|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|P|$Q|$5|R|S|T|A|$U|V]]|W|$5|R|S|T|A|$U|X]]]]

I had this problem as well. Although the manpage specifies "-o" or "--output" to save your output to a file, this does not actually work.

It seems that this was marked as "WontFix":
<a href="https://code.google.com/p/iperf/issues/detail?id=24" rel="nofollow noreferrer">https://code.google.com/p/iperf/issues/detail?id=24</a>:

<blockquote>
 Looks like -o/--output existed in a previous version but in not in the
 current version. The consensus in yesterday's meeting was that if
 --output existed then we should fix it, otherwise people should just use shell redirection and we'll mark this WontFix. So, WontFix.
</blockquote>

So maybe just use typescript or ">test.log" as suggested by <a href="https://stackoverflow.com/users/648682/paolo">Paolo</a>

I think the answer is given by Chiara Contoli in here: <a href="https://mailman.stanford.edu/pipermail/mininet-discuss/2014-October/005199.html" rel="nofollow noreferrer">iperf result in output file</a>

In summary:

<pre><code>h1.cmd('iperf -s &gt; server_output.txt &amp;')
h2.cmd('iperf -t 5 -c ', h1.IP() + ' &gt; client_output.txt &amp;')
</code></pre>

blocks|key|4450878|text|由于您是在python上运行它，保存结果的另一种方法是使用popen：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4450879|popen(+'<command>+>+<filename>',+shell=True)|code-block|syntax|javascript|4450880|例如：|4450881|popen('iperf+-s+-u+-i+1+>+outtest.txt',+shell=True)|4450882|您可以查看以下内容以了解更多信息：|4450883|https://github.com/mininet/mininet/wiki/Introduction-to-Mininet#popen|offset|length|4450884|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|0|0|0|1X|0|0^^$0|@$1|2|3|4|5|6|7|X|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|Y|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Z|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|10|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|11|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|12|8|@]|9|@$O|13|P|14|1|15]]|A|$]]|$1|Q|3|-4|5|6|7|16|8|@]|9|@]|A|$]]]|R|$S|$5|T|U|V|A|$W|N]]]]

Since you are running it on python, another method to save the result is to use popen:

<pre><code>popen( '&lt;command&gt; &gt; &lt;filename&gt;', shell=True)
</code></pre>

For example:

<pre><code>popen('iperf -s -u -i 1 &gt; outtest.txt', shell=True)
</code></pre>

You can check this for further information:

blocks|key|1789778|text|如果您需要将文件保存为txt格式。在客户机上运行cmd(adm)，然后您需要编写以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1789779|cd+c:\iperf3+iperf3.exe+-c+"you+server+address“-p+"port”-P+10+-w+32000+-t+0+>>+c:\iperf3\text.txt|1789780|(-t+0)+-在客户机上无限大，您将在cmd中看到黑屏。这很正常。您将看到服务器机器中的所有进程。测试完成后，在客户机上的cmd中需要推送ctrl%2B+c和之后(y)。在此之后，您在c:\iperf3\text.txt目录中的文件将收集有关这段时间的所有信息。如果您在cmd中按close，则此文件text.txt将为空。|offset|length|style|BOLD|1789781|建议在NotePad或WordPad中打开此文件以获得正确的视图。|1789782|entityMap^0|0|0|3M|V|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|P|8|@$F|Q|G|R|H|I]]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

If you need to save a file in the txt format.
On the client machine run cmd(adm) and after that you need to write this:

cd c:\iperf3
iperf3.exe -c "you server address" -p "port" -P 10 -w 32000 -t 0 >> c:\iperf3\text.txt

(-t 0) - infinity
On the client machine, you will see a black screen in cmd. It's normal. You will see all the process in the server machine. After your test, on the client machine in cmd need push ctrl+ c and after (y). 
Your file in directory c:\iperf3\text.txt after that collect all information about this period. 
If you push close in cmd this file text.txt will be empty.

Recommended open this file in NotePad or WordPad for the correct view.

I am running iperf between a set of hosts that are read from a txt file, here's how I am running it:

<pre><code>h1,h2 = net.getNodeByName(node_id_1, node_id_2)

net.iperf((h1, h2))
</code></pre>

It runs well and displays the results. But, I want to save the output of iperf result in a separate txt file. Does anyone know how I can apply it on the above code?

我在从txt文件读取的一组主机之间运行iperf，下面是我是如何运行它的：h1,h2 = net.getNodeByName(node_id_1, node_id_2)net.iperf((h1, h2))它运行良好，并显示结果。但是，我希望将iperf result的输出保存在一个单独的txt文件中。有谁知道我如何在上面的代码中应用它？
