Include an if statement and filter packets based on their prefix. If you find a packet with a name that starts with “/localhost”, you can safely ignore it.

<div class="">Thank you so much Prof. Spyros for your email. However, I need to calculate some metrics for just data messages which are requested by users and saved in the cache ( I do not want to consider to consider data packet generated by NFD) . How I can
access it? is there any field that can distinguish these data from each other?</div>

<div class="">Hello,</div>
<div class="">I would like to get name of content that are stored in the cache in forward.cpp so I wrote the below lines:</div>
<div class="">for(ns3::Ptr<ns3::ndn::cs::Entry> csentry= m_csFromNdnSim->Begin(); csentry!= m_csFromNdnSim->End(); csentry=m_csFromNdnSim->Next(csentry))<br class="">
{<br class="">
std::cout<<"the name"<<csentry->GetName()<<"is stored in node with id"<<node->GetId()<<"\n";<br class="">
<br class="">
}</div>
<div class=""><br class="">
</div>
<div class="">However, I notice this not only gives prefix that stored but also gives some event such as :</div>
<div class="">the name/localhost/nfd/faces/events/%FE%02is stored in node with id3</div>
<div class=""><br class="">
</div>
<div class="">what is the reason. how I can just access just the name of contents that are stored.</div>
<div class="">I will appreciate any help</div>
<div class="">best regards</div>
<div class="">Zeinab</div>
