[ndnSIM] How to trace the interest accessing each node?

[Saran Tarnoi]

Dear Alex and All,

I would like to record the interests and their numbers that access each
node.
Specifically, I want to study the characteristic of the interest traffic at
different nodes.
I tried observing the received packets at each face in ndn:Face but I could
neither get the header nor type of the packet.
I followed this code (
http://polythinking.wordpress.com/2012/05/30/ns-3-network-simulator-how-to-find-a-specific-header-in-packet-in-ns-3/)
but it didn't work.

To add header to a packet, we can do:
packet->AddHeader (interestHeader);

Is there any way to do:
packet->GetContentName ();
packet->GetType ();
and get the output like:
"/prefix/0"
"Interest or Data"
?

Would you kindly tell me how can I get that information?
Thanks in advance for your time.
