Hi Joel, Sure, I will put a note. Regards, Sudhin From: "Joel M. Halpern" <jmh@joelhalpern.com> Sent: Thu, 17 Jun 2021 19:23:29 To: "bmwg@ietf.org" <bmwg@ietf.org> Cc: rtg-dir@ietf.org Subject: Re: [RTG-DIR] bmwg Digest, Vol 200, Issue 6 iWe couldn't verify the sender of this email.Thank you Sudhin. If the observations have to be generic, then could you at least say that this will be measured by observing the network management counters that the implementations has chosen to expose? And maybe even note that this will likely need to be specific to the implementation as said coutners are not currently standardized?
