Hi David, > We are starting to use the new api, it looks good, thanks for this. > Documentation would be very appreciated Splendid. Any suggestions for improvements, please let us know. > Any idea how much more evolving it’s going to do? The base stuff should be pretty stable. So the evolving is likely to be more around adding more counters, possibly some name changes / hierarchy changes as we add counters. I'm also looking at simplifying the counter "key" data structure, to allow for less dependency on the VPP data structures. But that depends on the users of the API. I also want to solidify the client side API more, and possibly also add a few language bindings for it. Again, it depends on interest. And I'm hoping to have a sample "top" like application available soon (unless someone else beats me to it. hint, hint). > Is there any impact on performance of vector processing from using it?

Re: [SUSPECTED SPAM] [vpp-dev] Interface Mib II counters
I would expect very little if any measurable effect on forwarding performance. At least for the counters that I moved to the stats segment: vpp was already maintaining them. Not much changed. HTH...
