 Monitoring & Management
 -----------------------
 
-This section addresses data collection and event processing
-functionality that is directly dependent on the interfaces
-provided by the VNFs' APIs. These can be in the form of asynchronous
-interfaces for event, fault notifications, and autonomous data streams.
-They can also be synchronous interfaces for on-demand requests to
-retrieve various performance, usage, and other event information.
-
-The target direction for VNF interfaces is to employ APIs that are
-implemented utilizing standardized messaging and modeling protocols
-over standardized transports. Migrating to a virtualized environment
-presents a tremendous opportunity to eliminate the need for proprietary
-interfaces for VNF provider equipment while removing the traditional
-boundaries between Network Management Systems and Element Management
-Systems. Additionally, VNFs provide the ability to instrument the
-networking applications by creating event records to test and monitor
-end-to-end data flow through the network, similar to what physical or
-virtual probes provide without the need to insert probes at various
-points in the network. The VNF providers must be able to provide the
-aforementioned set of required data directly to the ONAP collection
-layer using standardized interfaces.

 Data Model for Event Records
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-This section describes the data model for the collection of telemetry
-data from VNFs by Service Providers (SPs) to manage VNF health and
-runtime lifecycle. This data model is referred to as the VNF Event
-Streaming (VES) specifications. While this document is focused on
-specifying some of the records from the ONAP perspective, there may
-be other external bodies using the same framework to specify additional
-records. For example, OPNFV has a VES project that is looking to specify
-records for OpenStack's internal telemetry to manage Application (VNFs),
-physical and virtual infrastructure (compute, storage, network devices),
-and virtual infrastructure managers (cloud controllers, SDN controllers).
-Note that any configurable parameters for these data records (e.g.,
-frequency, granularity, policy-based configuration) will be managed
-using the “Configuration” framework described in the prior sections
-of this document.
+This section describes the data model for the collection of telemetry data from
+xNFs by Service Providers (SPs) to manage xNF health and run-time life cycle.
+This data model is referred to as the VES Data Model. The VES acronym originally
+stood for Virtual-function Event Streaming, but VES has been generalized to
+support network-function event streaming, whether virtualized or not.
+
+The VES Data Model describes a vendor-agnostic common vocabulary of event
+payloads. Vendor-specific, product-specific or service-specific data is
+supported by the inclusion of a flexible additional information field structure.
+The VES Data Models' common vocabulary is used to drive standard and automated
+data analytics (policy-driven analytics) within the ONAP DCAE Framework.
+
+While this document is focused on specifying some of the records from the ONAP
+perspective, there may be other external bodies using the same framework to
+specify additional records. For example, OPNFV has a VES project that is
+looking to specify records for OpenStack’s internal telemetry to manage
+application (xNFs), physical and virtual infrastructure (compute, storage,
+network devices, etc.) and virtual infrastructure managers (cloud controllers,
+SDN controllers). It uses ONAP’s VES Agent to generate VES events from the xNF
+and Intel’s collectD agent to generate infrastructure VES events. Note that any
+configurable parameters for these data records (e.g., frequency, granularity,
+policy-based configuration) will be managed using the “Configuration” framework
+described in the prior sections of this document. The infrastructure metrics have
+been funneled via the ONAP Multi-VIM Project and are now included in current
+specifications.
 
 The Data Model consists of:
 
--  Common Header Record: This data structure precedes each of the
-   Technology Independent and Technology Specific records sections of
-   the data model.
-
--  Technology Independent Records: This version of the document
-   specifies the model for Fault, Heartbeat, State Change, Syslog,
-   Threshold Crossing Alerts, and VNF Scaling* (short for
-   measurementForVfScalingFields – actual name used in JSON
-   specification) records. In the future, these may be extended to
-   support other types of technology independent records. Each of
-   these records allows additional fields (name/ value pairs) for
-   extensibility. The VNF provider can use these VNF Provider-specific
-   additional fields to provide additional information that may be
-   relevant to the managing systems.
-
--  Technology Specific Records: This version of the document specifies
-   the model for Mobile Flow records, Signaling and Voice Quality records.
-   In the future, these may be extended to support other types of records
-   (e.g. Network Fabric, Security records, etc.). Each of these records
-   allows additional fields (name/value pairs) for extensibility. The VNF
-   providers can use these VNF-specific additional fields to provide
-   additional information that may be relevant to the managing systems.
-   A placeholder for additional technology specific areas of interest to
-   be defined in the future documents has been depicted.

+
+   * Technology Independent Records: This version of the document specifies the

 Event Records - Data Structure Description
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 The data structure for event records consists of:
 
--  a Common Event Header block;
+-  a Common Event Header block; and
 
--  zero or more technology independent domain blocks; and
+-  zero (Heartbeat) or more technology independent domain blocks; or
 
-   -  e.g., Fault domain, State Change domain, Syslog domain, etc.
+   -  e.g. Fault, Measurements, Notification, PNF Registration, State Change,
+      Syslog, TCA, Other Fields etc.
 
--  zero or more technology specific domain blocks.
+-  technology specific domain blocks.
 
-   -  e.g., Mobile Flow domain, Signaling domain, Voice Quality domain,
-      etc.
+   -  e.g. Mobile Flow, Signaling, Voice Quality, etc.
 
 Common Event Header
 ~~~~~~~~~~~~~~~~~~~~~
 
 The common header that precedes any of the domain-specific records contains
-information identifying the type of record to follow, information about
-the sender and other identifying characteristics related to timestamp,
-sequence number, etc.
+information identifying the type of record to follow, information about the
+sender and other identifying characteristics related to the domain and event.
+(e.g., name, priority, sequence number, source, timestamp, type, etc.).

+   :target: VNF
+   :introduced: casablanca
+   :validation_mode: in_service
+   :impacts: dcae
+   :keyword: MUST
+
+   The VNF **MUST** produce VES events that include the following mandatory
+   fields in the common event header
+
+    * ``domain`` - the event domain enumeration
+    * ``eventId`` - the event key unique to the event source
+    * ``eventName`` - the unique event name
+    * ``lastEpochMicrosec`` - the latest unix time (aka epoch time) associated
+      with the event
+    * ``priority`` - the processing priority enumeration
+    * ``reportingEntityName`` - name of the entity reporting the event or
+      detecting a problem in another xNF
+    * ``sequence`` - the ordering of events communicated by an event source
+    * ``sourceName`` - name of the entity experiencing the event issue, which
+      may be detected and reported by a separate reporting entity
+    * ``startEpochMicrosec`` - the earliest unix time (aka epoch time)
+      associated with the event
+    * ``version`` - the version of the event header
+    * ``vesEventListenerVersion`` - Version of the VES event listener API spec
+      that this event is compliant with
 
 Technology Independent Records – Fault Fields
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-The Fault Record, describing a condition in the Fault domain, contains
-information about the fault such as the entity under fault, the
-severity, resulting status, etc.
+The current version of the data model supports the following technology
+independent event records:
+
+   * ``Fault`` - the Fault Record, describing a condition in the Fault domain,
+     contains information about device failures. The fault event provides data
+     such as the entity experiencing a fault, the severity, resulting status,
+     etc.
+
+   * ``Heartbeat`` - the Heartbeat Record provides an optional structure for
+     communicating information about device health. Heartbeat records would only
+     have the Common Event Header block. An optional heartbeat domain is
+     available to specify information such as heartbeat interval and recommended
+     action upon missing heartbeat interval. Heartbeat avoids the need to ping
+     a device.  A communication failure can be determined via missing heartbeat
+     events being delivered to DCAE and appropriate action (e.g. restart VM,
+     rebuild xNF or create ticket) can be taken by DCAE CLAMP.
+
+   * ``Measurements`` - the Measurements Record contains information about xNF
+     and xNF resource structure and its condition to help in the management of
+     the resources for purposes of capacity planning, elastic scaling,
+     performance management and service assurance.  These are soft alarms
+     providing an opportunity for proactive maintenance.
+
+   * ``Notification`` - the Notification Record provides a structure for
+     communicating notification information from the NF. It can contain
+     notification information related to the current operational state that is
+     reported by the NF. As an example, when cards or port name of the entity
+     have changed state. (e.g., offline -> online) Other use cases include
+     notification of file ready for collection using Bulk Data Transfer or
+     notification on configuration changes to a device.
+
+   * ``Other`` - the Other Record defines fields for events that do not have a
+     defined domain but are needed to be collected and sent to DCAE. This
+     record provides a mechanism to convey a complex set of fields (possibly
+     nested or opaque) and is purely intended to address miscellaneous needs
+     such as addressing time-to-market considerations or other proof-of-concept
+     evaluations. Hence, use of this record type is discouraged and should be
+     minimized.  (Note: the Other domain could be used to create and test new
+     domain ideas.)
+
+   * ``pnfRegistration`` - the pnfRegistration Record provides a structure for
+     registration of a physical network function. The pnfRegistration Record can
+     contain information about attributes related to the physical network function
+     including serial number, software revision, unit type and vendor name.
+
+   * ``State Change`` - the State Change Record provides a structure for
+     communicating information about data flow through the xNF. The State
+     Change Record can contain information about state change related to
+     physical device that is reported by the xNF. As an example, when cards or
+     port name of the entity that has changed state.  Note: The Notification
+     Domain can also communicate similar information.
+
+   * ``Syslog`` - the Syslog Record provides a structure for communicating any
+     type of information that may be logged by the xNF. It can contain
+     information about system internal events, status, errors, etc. It is
+     recommended that low volume control or session logs are communicated via a
+     push mechanism, while other large volume logs should be sent via file
+     transfer.
+
+   * ``Threshold Crossing Alert`` - the Threshold Crossing Alert (TCA) Record
+     provides a structure for communicating information about threshold
+     crossing alerts. It uses data from the Measurement or a similar domain to
+     watch for a Key Performance Indicator (KPI) threshold that has been
+     crossed. TCA provides alert definitions and types, actions, events,
+     timestamps and physical or logical details.
+
+

+     described in the future documents.
 
-Technology Independent Records – Syslog Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Miscellaneous
+~~~~~~~~~~~~~
 
-The Syslog Record provides a structure for communicating any type of
-information that may be logged by the VNF. It can contain information

-The VNF Scaling\* (short for measurementForVfScalingFields –
-actual name used in JSON specification) Record contains information
-about VNF and VNF resource structure and its condition to help in
-the management of the resources for purposes of elastic scaling.
+   The VNF, when publishing events, **MUST** pass all information it is
+   able to collect even if the information field is identified as optional.

 Transports and Protocols Supporting Resource Interfaces
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-Delivery of data from VNFs to ONAP must use the common transport
-mechanisms and protocols for all VNFs as defined in this document.
-Transport mechanisms and protocols have been selected to enable both

-encoding provides self-documenting content, so data fields can be
-changed as needs evolve, while minimizing changes to data delivery.
-
-The term 'Event Record' is used throughout this document to represent
-various forms of telemetry or instrumentation made available by the
-VNF including, faults, status events, various other types of VNF
-measurements and logs. Headers received by themselves must be used
-as heartbeat indicators. Common structures and delivery protocols for
-other types of data will be given in future versions of this document
-as we get more insight into data volumes and required processing.
-
-In the following sections, we provide options for encoding, serialization

 VNF telemetry via standardized interface
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-All VNF telemetry data (e.g. fault event records, syslog records,
-performance records, etc.) need to be delivered to ONAP using the
-standardized models and interfaces described in this section.
+.. req::

+   :introduced: casablanca

+   :validation_mode: in_service
 
-Encoding and Serialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
+   The xNF MUST produce heartbeat indicators consisting of events containing
+   the common event header only per the VES Listener Specification.
 
-Content delivered from VNFs to ONAP is to be encoded and serialized using JSON:
 
 JSON
 ~~~~~~~~~~~~~~~~~~
 
-
 .. req::
     :id: R-19624
     :target: XNF
     :keyword: MUST
 
-    The xNF **MUST** encode and serialize content delivered to
-    ONAP using JSON (RFC 7159) plain text format. High-volume data
-    is to be encoded and serialized using `Avro <http://avro.apache.org/>`_,
-    where the Avro [#7.4.1]_ data format are described using JSON.
-
-    Note:
-
-        - JSON plain text format is preferred for moderate volume data sets
-          (option 1), as JSON has the advantage of having well-understood simple
-          processing and being human-readable without additional decoding. Examples
-          of moderate volume data sets include the fault alarms and performance
-          alerts, heartbeat messages, measurements used for xNF scaling and syslogs.
-        - Binary format using Avro is preferred for high volume data sets
-          (option 2) such as mobility flow measurements and other high-volume
-          streaming events (such as mobility signaling events or SIP signaling)
-          or bulk data, as this will significantly reduce the volume of data
-          to be transmitted. As of the date of this document, all events are
-          reported using plain text JSON and REST.
-        - Avro content is self-documented, using a JSON schema. The JSON schema is
-          delivered along with the data content
-          (http://avro.apache.org/docs/current/ ). This means the presence and
-          position of data fields can be recognized automatically, as well as the
-          data format, definition and other attributes. Avro content can be
-          serialized as JSON tagged text or as binary. In binary format, the
-          JSON schema is included as a separate data block, so the content is
-          not tagged, further compressing the volume. For streaming data, Avro
-          will read the schema when the stream is established and apply the
-          schema to the received content.
