(Adding ALTO in cc since discussion on metrics is also relevant for that WG)
Hi Adrian, Dean, Another reference work we can consider is https://www.rfc-editor.org/rfc/rfc7666.html. This RFC provides several metrics as part of the MIB definition that could be leveraged on. Apart from that, I think we need to look at what current cloud / VI managers provide nowadays in terms of metrics (i.e., OpenStack, Kubernetes, etc) since the metrics that we could handle will be generated most probably for those non-IETF components. So a good exercise to start with would be to check and compare what kind of metrics these kind of sustems provide nowadays, and derive from that a common / abstract set of metrics that could be consumed by both CATS and ALTO. In https://www.ietf.org/archive/id/draft-contreras-alto-service-edge-07.txt there is reference as well to CNTT and Anuket efforts, which probably need to be revisited and updated. All in all, an exercise of collecting different sources is needed, and from that select relevant metrics for the purposes of ALTO and CATS.

Interesting coincidence of acronyms. This work does, indeed, look relevant. Cheers, Adrian From: Dean Bogdanovic <falk...@mac.com<mailto:falk...@mac.com>> Sent: 07 April 2023 19:01 To: Adrian Farrel <adr...@olddog.co.uk<mailto:adr...@olddog.co.uk>> Cc: c...@ietf.org<mailto:c...@ietf.org> Subject: Re: DMDTF and CATS Metrics Hi, I was referring to the work that is being done by Redfish and has been presented at IETF 98 by Joe White (https://datatracker.ietf.org/meeting/98/materials/slides-98-rtgwg-yang-device-profile-for-redfish-network-management-draft-wbl-rtgwg-baseline-switch-model-draft-wbl-rtgwg-yang-ci-profile-bkgd-00). This work didn’t continue within the IETF, but Redfish has published and keeps developing and maintaining their data model (https://www.dmtf.org/sites/default/files/standards/documents/DSP0268_2022.2.pdf]. They did lot of compute resource modeling and taking a loot at their work is very useful IMO. DMTF folks know lot about compute, so it might be worth even rekindling the joint work.

I did some digging and found the presentation by the IEEE 802.3cf - YANG Data Model Definitions Task Force. The purpose of that work was to migrate relevant MIB modules to YANG. The slides for that session are at https://datatracker.ietf.org/meeting/98/materials/slides-98-netmod-sessa-iee e-8023cf-yang-data-model-definitions-task-force-00 The presentation is at https://youtu.be/hUSx_Ua3MnY?t=3326 and the presenter was Rob Wilton who would, I'm sure, be responsive to questions. I'm not clear how much this is relevant. Dean, was that the presentation you were referring to?
