     Per-Node Capabilities for Optimum Operational Data Collection
            draft-claise-netconf-metadata-for-collection-00

Abstract

   This document proposes a YANG module that provides per-node
   capabilities for optimum operational data collection.  This YANG
   module augments the YANG Modules for describing System Capabilities
   and YANG-Push Notification capabilities.

   This module defines augmented nodes to publish the metadata
   information specific to YANG node-identifier as per ietf-system-
   capabilities datatree.

   Complementary RPCs, based on the same node capabilities, simplify the
   data collection oeprations.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

   The term Client and Server are specified in [RFC8342].

   The term Implementation-time and Run-time are specified in
   [I-D.ietf-netconf-notification-capabilities].

2.  Introduction

   This document specifies a way to learn from the devices how granular
   its telemetry and data can be to provide the best post-processing
   analytics.  In the end, the service assurance architecture
   [I-D.claise-opsawg-service-assurance-architecture], it's not
   sufficient to simply stream (or poll) telemetry data, it is equally
