1.  Introduction

   YANG "Custom Subscription to Event Notifications" model
   [I-D.ietf-netconf-subscribed-notifications] allows for a network
   client automation of network remote monitoring.  Specifically, using
   this model, a network client can subscribe on and receive one or more
   data streams, each associated with one or more events defined by YANG
   model(s) governing the network's YANG data store(s).  The client can
   also tailor said streams to its needs by specifying filters on the
   streams contents, but, otherwise, the client has no control on the
   stream contents.  For example, the client has no way of expanding a
   stream to carry additional information that was not defined to be a
   part of said stream.

   YANG "Subscribing to YANG datastore push updates" model
   [I-D.ietf-netconf-yang-push], which is an augmentation of the "Custom
   Subscription to Event Notifications" model, defines a higher level of
   network remote monitoring automation - it allows for the client
   itself to define the origins, trigger/maintain conditions and
   contents of data streams to be sent by the network to the client.
   This capability is modeled via target-trigger-notify constructs,
   which allow for the client to specify data store nodes of interest
   and, possibly, sub-trees rooted by them (targets), conditions to
   trigger and maintain associated with them streams (e.g. particular
   change(s) in one or more of the nodes attributes), the contents of
   the streams and filters to further fine-tune the streams according to
   the client's needs.
