you can modify the consumer and producer apps to add some counters for the metrics you need and print the value of the counters at end of your simulation.

Another way to do that is to use some tracer that is provided by ndnSIM, e.g., the app delay tracer:

I'm wondering how to calculate the satisfaction ratio, the average ratio of each client(i.e., the sum of satisfaction ratio of each client / the number of clients) or the overall ratio of legitimate Interests(i.e.,the sum of # of all the received Data packets by clients / the sum of # of all the sent out Interest packets by clients ).
