What certainly would make sense to do, is to put a wrapper on top of
vpp_stats.py that gives you a higher level API of accessing the stats.
E.g. a get_interface_counters(). The stat segment also contains the name to
interface index mapping (/if/names).
Want to have a go?
I am also exploring putting much more information into the stat segment,
essentially making it into an operational data store (RFC8342). Don't hold your
breath. But any help appreciated.
Cheers,
Ole
