Completing Netflow v9 implementation

[b5y]

Hello!

I need netflow v9 parser to extract data from nfcapd files. Namely, getting some information about bytes, destination and source addresses. I have used nfdump to run it from golang application. Unfortunately, it is not very fast when files have size more than 1 GB. The only way to fix it is to read nfcapd files directly with golang using goroutines and semaphores.

All I want is to proceed on working with current implementation of netflow v9 packet. I will wonder if someone helps me. If you have chat in slack/IRC/gitter, then please tell me where it is possible to find you. If someone is already started to implement, please tell me. Maybe we could collaborate and finish our goal quickly.

Some words about going implementation. I want to implement it based on nfdump tool by parsing fields relating to bytes and IP addresses. I checked out post from CISCO and want to use it too.

Any suggestions and tips will be highly appreciated.

BR,
Mehti
