          A YANG Data model for Policy based Event Management
                     draft-wwx-netmod-event-yang-01

Abstract

   [RFC8328] defines a policy-based management framework that allow
   definition of a data model to be used to represent high-level,
   possibly network-wide policies.  This document defines an YANG data
   model for the policy based event management [RFC7950].  The policy
   based Event YANG provides the ability for the network management
   function (within a controller, an orchestrator, or a network element)
   to control the configuration and monitor state change on the network
   element and take simple and instant action when a trigger condition
   on the system state is met.

1.  Introduction

   [RFC8328] defines a policy-based management framework that allow
   definition of a data model to be used to represent high-level,
   possibly network-wide policies.  This document defines an policy
   based Event Management YANG data model [RFC7950].  The policy based
   Event management YANG provides the ability for the network management
   function (within a controller, an orchestrator, or a network element)
   to monitor state changes on the network element and take simple and
   instant action when a trigger condition on the system state is met.

   The data model in this document is designed to be compliant with the
   Network Management Datastore Architecture (NMDA) [RFC8342].
