Create Custom Statistics Output

edit

I'm working on a project that is intended to analyse all the broadcast packets(Ex.: ARP, ND.) on Internet Exchange Points and create statistics of it.

Up to now I already have some usable code in bash. Using the output of "tshark -r" with some display filters, and abusing of pipeling in bash with sort, uniq, cut, awk...

But I'm Imagining that I'm rediscovering th wheel.

I possible to do some custom statistics outputs? For example count how many ARP packets were sent searching for any IP address?
