<div dir="ltr">Good to know. Very relevant discussion to my questions.

<div> </div>
</div><div><div class="h5">
<div>
<div dir="ltr">I read pretty interesting discussion on NFD mail archive regarding measuring/improving performance for PIT and FIB.
<div><br>
</div>
<div>I am trying to test performance of PIT, FIB in terms of time response for variety of interests and large number of entries in PIT and FIB.</div>
<div>I decided to print hit/miss scenario log for both. I just want to double check if NFD already have logging module available for this?</div>
<div><br>
</div>
<div>Are below 2 files that I can add my logs to, to see them in execution? Correct me.These 2 files doesn't have any logging module added.</div>

<div> </div>
<div><br>
</div>
<div>Which nfd modules should be used to during tracing? <br>
<br>
</div>
<div>
<div>Available logging modules: </div>
<div>AccessStrategy, AsfMeasurements, AsfStrategy, AutoPrefixPropagator, BestRouteStrategy2, ClientControlStrategy, CommandAuthenticator, ContentStore, CsPolicy, DeadNonceList, EthernetFactory, EthernetTransport,FaceManager , FaceSystem .FaceTable ,FibManager
