[ndnSIM] Calculate Hit Rate from Spesific Nodes in NFD Content Store

[mdparamartha95 at students.itb.ac.id]

Hi Junxiao, 
Thank you for your answer. 
Can we count hit/miss from each node using the forwarder? 
Thank you, 

Best Regards, 
Adi Paramartha

Hi Adi 

NFD already has CS hit/miss counters: 

1. Get a hold of Forwarder instance. 
2. Read the counter with forwarder.getCounters().nCsHits and forwarder.getCounters().nCsMisses. 

There’s no need to modify any callbacks. 

Yours, Junxiao

I had a problem to calculate the hit rate from the spesific node in NFD Content Store, 

For example, I had installed cs-policy-lru in 5 nodes. 

However, I just want to trace the performance of nodes 1 instead of nodes 2,3,4 or 5 . 

As long as my experience, in cs.cpp using a callback function and add some increment if hitcallback or misscallback is called. 

But results show that the increment works with all nodes, and give me entire nodes hit/miss rate. Not hit/miss rate for specific nodes. 

How can I calculate the hit/miss rate from specific nodes?
