Hi Vince
Thank you so much for the details.
>>>a: _ nfd-log-level=DEBUG
>>>The log will be written to the node’s home folder (by default,
/tmp/$NODE_NAME).
Is there some available parser for these logs in MiniNdn ? (for example
for NFD and/or NLSR logs).
Or
How would you recommend to read them ?.
Regards
Percy
