Hi Alex,
Thank you for your very quick answers :-)
I am going to print each PIT entry in a specific router in each second 
(in a periodic time) with:
(1) Interest name (e.g., prefix), (2) RTT time of each satisfied 
Interest, (3) Interface number of each interest packet. My mean of RTT 
is the satisfaction time of each interest packet to receive desired 
content data. If an Interest packet has not been satisfied, the RTT can 
set to zero or infinity.

Would you mind please telling me how is it possible to configure?

If you want this additional info, the tracing is a little bit more complicated and you can check another example (https://github.com/NDN-Routing/ndnSIM/blob/master/examples/ndn-simple-with-pit-operation-stats.cc).
