<p>You can issue any command available in the system on a node.</p>
<p>If you have your own application that is not installed in the system you can give the whole path to the application,</p>
<p><br>
</p>
<p>For example:</p>
<p><br>
</p>
<p>for node in net.hosts:</p>
<p> <span>if node.name == "nodename":</span></p>
<p><span> node.cmd("/path/to/myapp options > /dev/null &")</span></p>
<p><span><br>
</span></p>
<p><span>Metric collection can be done by redirecting output of applications.</span></p>
<p>If you want metric collection from NFD or NLSR you will have to turn on logging (modules can be specified in</p>
<p>the nfd.conf file at /usr/local/etc/ndn/nfd.conf or if this is not present at: <span style="font-family: Calibri, Arial, Helvetica, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">/usr/local/etc/ndn/nfd.conf.sample</span>).</p>
<p><br>
</p>
<p>Or collect ndndump such as:</p>
<p></p>
<div>for host in net.hosts:<br>
for intf in host.intfNames():<br>
ndnDumpOutputFile = "dump.%s" % intf<br>
host.cmd("sudo ndndump -i %s > %s &" % (intf, ndnDumpOutputFile)) # can specify any filter with -f option</div>
<div><br>
</div>
<p></p>
<p>Emulation is in the sense that multiple instances of NFD and NLSR are being run in real time.</p>

<p>Currently richer documentation is not available but Mini-NDN is based on Mininet which has a good documentation for the python API: <a href="https://github.com/mininet/mininet/wiki/Documentation" class="OWAAutoLink" id="LPlnk503748" previewremoved="true">https://github.com/mininet/mininet/wiki/Documentation</a></p>

<p dir="ltr">Dear community</p>
<p dir="ltr">I'm new with mini ndn<br>
Fortunately installation went fine <br>
I would like now to write an experiment with many data flows between my topology nodes using producers and consumers</p>
<p dir="ltr">Documentation does not really help since only ndnping is showed</p>
<p dir="ltr">Is there any richer experiment example or tutorial ?</p>
<p dir="ltr">My second question is How's to collect metrics once the emulation done ?</p>
<p dir="ltr">Best regards </p>
