Introduction
^^^^^^^^^^^^

This document describes the RESTful interface for the VES Event
Listener. 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 Event Listener is
capable of receiving any event sent in the VES Common Event Format. The
Common Event Format is expressed in JSON schema in section 4 of this
document. In the Common Event Format, an event consists of a required
Common Event Header block (i.e., object) accompanied by zero or more
event domain blocks.

It should be understood that events are well structured packages of
information, identified by an eventName, which are asynchronously
communicated to subscribers who are interested in the eventName. Events
can convey measurements, faults, syslogs, threshold crossing alerts and
other types of information. Events are simply a way of communicating
well-structured packages of information to one or more instances of an
Event Listener service.

This document describes a RESTful connectionless push event listener
that is capable of receiving single events or batches of events in the
Common Event Format. In future, additional documents may describe other
transports which make use of persistent TCP connections for high volumes
of streaming events.

Event Registration
~~~~~~~~~~~~~~~~~~

All events must be compliant with the common event format, but specific
events identified by their eventNames, may require that certain fields,
which are optional in the common event format, be present when they are
published. For example, a specific eventName may require that specific
name-value pairs be present in the extensible structures provided within
the Common Event Format.

Events are registered using an extensible YAML format (defined in a
separate document), which specifies, for each eventName, the fields that
are required, what field values may be sent, and any special handling
that should be performed on those eventNames.

Naming Standards for eventName
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To prevent naming collisions, eventNames sent as part of the
commonEventHeader, should conform to the following naming convention
designed to summarize the purpose and type of the event, and to ensure
the uniqueness of the eventName:

    {DomainAbbreviation}\_{PublisherName}\_{Description}

Each underscore-separated subfield above must start with a capital
letter and use camel-casing to separate words and acronyms. Acronyms
must capitalize only the first letter of the acronym. Spaces and
underscores should not appear within any subfield.

The DomainAbbreviation subfield derives from the ‘domain’ field in the
commonEventHeader, as specified below:

-  ‘Fault’ for the fault domain

-  ‘Heartbeat’ for the heartbeat domain

-  ‘Measurement’ for the measurement domain

-  ‘MobileFlow’ for the mobileFlow domain

-  ‘Notification’ for the notification domain

-  ‘Other’ for the other domain

-  ‘Perf3gpp’ for the perf3gpp domain

-  ‘PnfReg’ for the pnfRegistration domain

-  ‘SipSignaling’ for the sipSignaling domain

-  ‘StateChange’ for the stateChange domain

-  ‘Syslog’ for the syslog domain

-  ‘Tca’ for the thresholdCrossingAlert domain

-  ‘VoiceQuality’ for the voiceQuality domain

The PublisherName subfield describes the vendor product or application
publishing the event. This subfield conforms to the following
conventions:

-  Vendor products are specified as:

     {productName}-{vendorName}

    For example: Visbc-Metaswitch or Vdbe-Juniper, where a hyphen is
    used to separate the productName and vendorName subfields. Note that
    the productName and vendorName subfields must not include hyphens
    themselves.

    Organizing the information in this way will cause an alphabetical
    listing of eventNames to sort similar network functions together,
    rather than to sort them by vendor.

    The productName subfield may describe a NF or a NFC. Where NFC names
    may be reused across different NF’s, they should be specified as:

     {NfName}:{NfcName}

    where a colon is used to separate the NfName and NfcName subfields.
    Note that the NfName and NfcName subfields must not include colons
    themselves.

    The ProductName may also describe other types of vendor modules or
    components such as a VM, application or hostname. As with NFs and
    NFCs, parent:child relationships may be communicated using colon as
    a subfield delimiter.

-  Service providers who adopt the VES Common Event Format for internal
   use, may provide PublisherName without the vendorName subfield. They
   would typically identify an application, system, service or
   microservice publishing the event (e.g., ‘Policy’, ‘So’,
   ‘MobileCallRecording’ or ‘Dkat’). As with NFs and NFCs, parent:child
   relationships may be communicated using colon as a subfield delimiter
   (e.g., ApplicationName:ApplicationComponent).

The final subfield of the eventName name should describe, in a compact
camel case format the specific information being conveyed by the event.
In some cases, this final subfield may not be required (e.g., in the
case of certain heartbeats).

Examples of eventNames following the naming standards are provided
below:

-  Tca\_Vdbe-Ericsson\_CpuThresholdExceeded

-  Heartbeat\_Visbc:Mmc-Metaswitch

-  Syslog\_Vdbe-Ericsson

-  Fault\_MobileCallRecording\_PilotNumberPoolExhaustion

-  Other\_So:WanBonding\_InstantiationPart1Complete

EventId Use Cases Examples
~~~~~~~~~~~~~~~~~~~~~~~~~~~

[Author: Alok Gupta]:

eventId Examples:

Example 1: assumes a unique key for each domain consisting of domain
followed by an integer domainnnnnnn e.g. fault000001, heartbeat000001,
mfvs000005

Example 2: assumes an integer key for all events nnnnnnnnn: 000000001,
00000002, 000000003

Rules:

1. All domains except Fault: each time a subsequent event is sent the
   integer part of eventId will increment by 1. Repeat of eventId
   assumes duplicate event. Sequence number is set to 0 for all domains
   except fault.

2. eventId construction for Fault Events:

   a. Most likely scenario

      i.   The sourceName on each Fault event is the NF Instance Name
           (pnf-name or vnf-name or vm-name) as entered in A&AI uniquely
           identifying this instance of the NF.

      ii.  The eventId on Fault events is the same every time a given
           fault is raised (onset), re-raised at fixed time interval,
           until it is cleared. Once the fault is cleared, a new eventId
           is used.

      iii. The startEpochMicrosec value for the Fault event is the
           timestamp for when that event is generated until a clear is
           sent.

      iv.  lastEpochMicrosec indicates the current event time.

      v.   The sequence number for each Fault event is set to 1 when the
           event is first raised, and increments each time the same
           Fault event is raised, until a clear is sent.

   .. image:: Use-Case-1.png

   b. Alternative scenario: for vNF when fault event status is not
      maintained.

      i.   The sourceName on each Fault event is the NF Instance Name
           (pnf-name or vnf-name or vm-name) as entered in A&AI uniquely
           identifying this instance of the NF.

      ii.  The eventId on Fault events is the same every time a given
           fault is raised or cleared, even if it is re-raised after it
           had previously cleared.  So, for example, if EMS loses
           contact with a particular device then a Fault event might be
           sent for a raise, re-raise (because EMS has re-tried and
           still can’t contact the device), clear (because EMS has
           re-tried and it can contact the device) and then raise again
           (because EMS has lost contact with the device again).  The
           same eventId is used for all 4 of those Fault events.

      iii. The startEpochMicrosec value for each Fault event is the
           timestamp for when that event is generated, not when the
           fault first occurred.  So all 4 of the Fault events in the
           previous bullet point would have a different timestamp.

      iv.  lastEpochMicrosec indicates the current event time.

      v.   The sequence number for each Fault event is currently set to
           0 on a raise and 1 on a clear.  We could change that so that
           each Fault event is given a new monotonically increasing
           sequence number whether it is a raise or a clear if that is
           helpful (which is reset to 0 if the VM restarts) but they
           won’t be consecutive.

Measurement Expansion Fields
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When expansion fields are used, the goal is to avoid custom development
by the service provider collecting the fields, since custom development
adds obvious cost, delay and resource overhead. In the domain of
measurements, it is expected that a high percentage (perhaps as high as
90 percent) of use cases for extensible fields can be satisfied by using
the additionalMeasurements arrayOfNamedHashMap data structure in
combination with a YAML registration file (provided at design time). The
YAML registration file conveys meta-information about the processing of
additionalMeasurements. For more information, please see the VES Event
Registration specification and in particular the aggregationRole, castTo
and isHomogeneous keywords.

Syslogs
~~~~~~~~

Syslog’s can be classified as either Control or Session/Traffic. They
differ by message content and expected volume: 

-  Control logs are generally free-form human-readable text used for
   reporting errors or warnings supporting the operation and
   troubleshooting of NFs.  The volume of these logs is typically less
   than 2k per day.

-  Session logs use common structured fields to report normal NF
   processing such as DNS lookups or firewall rules processed.  The
   volume of these logs is typically greater than 1k per hour (and
   sometimes as high as 10k per second).

VES supports both classes of syslog, however VES is only recommended for
control logs or for lower volume session logs, less than 60k per hour.
High volume session logging should use a file-based transport solution.

Support for Protocols Other Than HTTPS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This API specification describes an HTTPS RESTful interface using the
JSON content-type.

Alternative API specifications may be provided in future using Google
Protobuf, websockets, or Apache Avro.

Versioning
~~~~~~~~~~~

Three types of version numbers supported by this specification:

-  The API specification itself is versioned. Going forward, the major
   number of the specification version will be incremented whenever any
   change could break an existing client (e.g., a field name is deleted
   or changed). All other changes to the spec (e.g., a field name is
   added, or text changes are made to the specification itself) will
   increment only the minor number or patch number. Note that the major
   number appears in REST resource URLs as v# (where ‘#’ is the major
   number). Minor and patch numbers are communicated in HTTP headers.
   For more information, see the API Versioning writeup in section 6.1.

-  The JSON schema is versioned. Going forward, the major number of the
   JSON schema will be incremented whenever any change could break an
   existing client (e.g., a field name is deleted or changed). All other
   changes to the schema (e.g., a field name is added or text changes
   are made to the field descriptions) will increment only the minor
   number or patch number.

-  The field blocks are versioned. Field blocks include the
   commonEventHeader and the domain blocks (e.g., the faultFields
   block). Going forward, the major number of each field block will be
   incremented whenever any change to that block could break an existing
   client (e.g., a field name is deleted or changed). All other changes
   to that block (e.g., a field name is added or text changes are made
   to the field descriptions) will increment only the minor number.

Field Block Versions
+++++++++++++++++++++

A summary of the latest field block version enums as of this version of
the API spec is provided below:

-  commonEventHeader version 4.1 (note: the enum with support 4.0,
   4.0.1, 4.1 to avoid breaking clients of earlier versions of major
   version 4)

-  commonEventHeader vesEventListenerVersion enum: 7.1 (note: the enum
   will support 7.0, 7.0.1, 7.1 to avoid breaking clients of earlier
   versions of major version 7)

-  faultFieldsVersion:4.0

-  heartbeatFieldsVersion: 3.0

-  measurementFieldsVersion: 4.0

-  mobileFlowFieldsVersion: 4.0

-  notificationFieldsVersion: 2.0

-  otherFieldsVersion: 3.0

-  perf3gppFieldsVersion: 1.0

-  pnfRegistrationFieldsVersion: 2.0

-  sigSignalingFieldsVersion: 3.0

-  stateChangeFieldsVersion: 4.0

-  syslogFieldsVersion: 4.0

-  thresholdCrossingFieldsVersion: 4.0

-  voiceQualityFieldsVersion: 4.0

Security
^^^^^^^^

Event sources must identify themselves to the VES Event Listener.

In the future, support for 2-way SSL certificate authentication (aka
mutual SSL) may be provided (see the end of this Security section for
additional information) otherwise, event source credentials must be
passed using HTTP `Basic
Authentication <http://tools.ietf.org/html/rfc2617>`__.

Credentials must not be passed on the query string. Credentials must be
sent in an Authorization header as follows:

1. The username and password are formed into one string as
   “username:password”

2. The resulting string is Base64 encoded to produce the encoded
   credential.

3. The encoded credential is communicated in the header after the string
   “Authorization: Basic “

Because the credentials are merely encoded but not encrypted, HTTPS
(rather than HTTP) should be used. HTTPS will also encrypt and protect
event contents. TLS 1.2 or higher must be used.

Examples are provided below.

Mutual SSL Certificate Authentication
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If service provider VES Event Listener support for Mutual SSL
Certification Authentication is available, event sources must initialize
the HTTPS connection with TLS 1.2 or higher and execute mutual
authentication procedures according to
`RFC5246 <https://tools.ietf.org/html/rfc5246#section-7.4.6>`__. If
event source certificates cannot be verified or if certificate subject
(identity) is unknown to the VES Event Listener, then HTTP Basic
Authentication must be used as described above.

Resource Structure
^^^^^^^^^^^^^^^^^^

REST resources are defined with respect to a ServerRoot:

ServerRoot = /{optionalRoutingtPath}

The resource structure is provided below:

.. image:: rest-resource.png

Figure – REST Resource Structure

The {Domain} or FQDN above is typically provisioned into each
eventsource when it is instantiated. The {Port} above is typically 8443.

Common Event Format
^^^^^^^^^^^^^^^^^^^^

A JSON schema describing the Common Event Format is provided below and
is reproduced in the tables that follow.

:download:`JSON <CommonEventFormat_30.1_ONAP.json>` 


Note on optional fields:

    If the event publisher collects a field that is identified as
    optional in the data structures below, then the event publisher
    *must* send that field.

Note on extensible fields:

    VES contains various extensible structures (e.g., hashMap) that
    enable event publishers to send information that has not been
    explicitly defined in VES data structures.

-  Event publishers *must not* send information through extensible
   structures where VES has explicitly defined fields for that
   information. For example, event publishers *must not* send
   information like cpuIdle, through an extensible structure, because
   VES has explicitly defined a cpuUsage.cpuIdle field for the
   communication of that information.

-  Keys sent through extensible fields must use camel casing to separate
   words and acronyms; only the first letter of each acronym shall be
   capitalized.

| eventId                   | string                  | Yes         | Event key that is unique to the event source. The key must be unique within notification life cycle similar to EventID from 3GPP. It could be a sequential number, or a composite key formed from the event fields, such as domain\_sequence. The eventId should not include whitespace. For fault events, eventId is the eventId of the initial alarm; if the same alarm is raised again for changed, acknowledged or cleared cases, eventId must be the same as the initial alarm (along with the same startEpochMicrosec but with a different sequence number). Note: see section 1.3 for eventId use case examples.                                                                                                                                                                                                                        |

| startEpochMicrosec        | number                  | Yes         | the earliest unix time aka epoch time associated with the event from any component--as microseconds elapsed since 1 Jan 1970 not including leap seconds. For measurements and heartbeats, where events are collected over predefined intervals, startEpochMicrosec shall be rounded to the nearest interval boundary (e.g., the epoch equivalent of 3:00PM, 3:10PM, 3:20PM, etc…). For fault events, startEpochMicrosec is the timestamp of the initial alarm; if the same alarm is raised again for changed, acknowledged or cleared cases, startEpoch Microsec must be the same as the initial alarm (along with the same eventId and an incremental sequence number). For devices with no timing source (clock), the default value will be 0 and the VES collector will replace it with Collector time stamp (when the event is received)   |

Datatype: internalHeaderFields
++++++++++++++++++++++++++++++

The internalHeaderFields datatype is an undefined object which can
contain arbitrarily complex JSON structures. It is intended to be
defined separately by each service provider (e.g., AT&T) implementing
the VES Event Listener. The fields in internalHeaderFields are not
provided by any event source but instead are added by the VES Event
Listener service itself as part of an event enrichment process necessary
for efficient internal processing of events received by the VES Event
Listener.

RESTful Web Services Exceptions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

RESTful services generate and send exceptions to clients in response to
invocation errors. Exceptions send HTTP status codes (specified later in
this document for each operation). HTTP status codes may be followed by
an optional JSON exception structure described below. Two types of
exceptions may be defined: service exceptions and policy exceptions.

Service Exceptions
~~~~~~~~~~~~~~~~~~~

   When a service is not able to process a request, and retrying the
   request with the same information will also result in a failure, and
   the issue is not related to a service policy issue, then the service
   will issue a fault using the service exception fault message.
   Examples of service exceptions include invalid input, lack of
   availability of a required resource or a processing error.

   A service exception uses the letters 'SVC' at the beginning of the
   message identifier. ‘SVC’ service exceptions used by the VES Event
   Listener API are defined below.

    Table - Service Exceptions

Policy Exceptions
~~~~~~~~~~~~~~~~~~

   When a service is not able to complete because the request fails to
   meet a policy criteria, then the service will issue a fault using the
   policy exception fault message. To clarify how a policy exception
   differs from a service exception, consider that all the input to an
   operation may be valid as meeting the required input for the
   operation (thus no service exception), but using that input in the
   execution of the service may result in conditions that require the
   service not to complete. Examples of policy exceptions include
   privacy violations, requests not permitted under a governing service
   agreement or input content not acceptable to the service provider.

   A Policy Exception uses the letters 'POL' at the beginning of the
   message identifier. ‘POL’ policy exceptions used by the VES Event

Table - REST Operation Summary

Api Versioning
+++++++++++++++

apiVersion is used to describe the major version number of the event
listener API (which is the same as the major version number of this
specification). When this number changes, the implication is: the new
major version will break clients of older major versions in some way, if
they try to use the new API without modification (e.g., unmodified v1
clients would not be able to use v2 without error).

The Event Listener shall provide the following HTTP headers in response
to all requests. Additionally, clients may populate these headers on
requests to indicate the specific version they are interested in.

-  X-MinorVersion: 0

-  X-PatchVersion: 0

-  X-LatestVersion: 7.1

If a client requests major version 7 (per the REST resource URL) and
does not specify the above headers, then they will be provided with the
latest patch version of 7.0.x (which is 7.0.1). If the client wants a
particular minor version of major version 7, then they need to supply
the X-MinorVersion header with their request. For example, if they
request major version 7 with X-MinorVersion: 1, they will get the latest
patch version of 7.1, which is 7.1.0.

Buffering of Events 
++++++++++++++++++++

{ServerRoot} is defined in section 3 of this document, which defines the
REST resource URL. One or more FQDNs may be provisioned in an event
source when it is instantiated or updated. If an event source is unable
to reach any of the provisioned FQDNs, it should buffer the event data
specified below, up to a maximum of 1 hour, until a connection can be
established and the events can be successfully delivered to the VES
Event Listener service.

xNFs acting as event sources should not send syslog events to the VES
Event Listener during debug mode (which is controlled via the Netconf
management interface), but should store syslog events locally for
access, and possible FTP transfer, via the xNF console (e.g., command
line interface).

If the internal event source event buffer or local storage should
overflow, then the event source should send a Fault event, and should
discard events in a first-in, first-out (FIFO) manner (i.e., discard
oldest events first).

Message Size
+++++++++++++++

Message size should be limited to 2 megabytes of uncompressed text sent
as application/json.

Operation: publishAnyEvent
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Functional Behavior
+++++++++++++++++++++

Allows authorized clients to publish any single event to the VES event
listener.

-  Supports only secure HTTPS (one way SSL) access.

-  Uses the HTTP verb POST

-  Supports JSON content types

-  Provides HTTP response codes as well as Service and Policy error
   messages

Terminology
^^^^^^^^^^^^

Terminology used in this document is summarized below:

**A&AI**. Active & Available Inventory is the ONAP component that
provides data views of Customer Subscriptions, Products, Services,
Resources, and their relationships.

**Alarm Condition**. Short name of the alarm condition/problem, such as
a trap name.

**APPC (formerly APP-C)**. Application Controller. Handles the life
cycle management of Virtual Network Functions (VNFs).

**ASDC**. AT&T Service Design and Creation Platform: the original name
for the SDC. Replaced by SDC.

**Common Event Format**. A JSON schema describing events sent to the VES
Event Listener.

**Common Event Header**. A component of the Common Event Format JSON
structure. This datatype consists of fields common to all events.

**DCAE**. Data Collection Analysis and Events. DCAE is the ONAP
subsystem that supports closed loop control and higher-level correlation
for business and operations activities. DCAE collects performance,
usage, and configuration data, provides computation of analytics, aids
in trouble-shooting and management, and publishes event, data, and
analytics to the rest of the ONAP system for FCAPS functionality.

**DMaaP.** Data Movement as a Platform. A set of common services
provided by ONAP, including a Message Router, Data Router, and a Data
Bus Controller.

**Domain**. In VES, an event ‘domain’ identifies a broad category of
events (e.g., ‘fault’ or ‘measurement’), each of which is associated
with a VES domain field block, which is sent with the commonEventHeader
when events of that category are generated.

**ECOMP**. Enhanced Control, Orchestration, Management and Policy
preceded ONAP and is the name given to AT&T’s instance of the ONAP
platform.

**Epoch**. The number of seconds that have elapsed since
00:00:00 \ `Coordinated Universal
Time <https://en.wikipedia.org/wiki/Coordinated_Universal_Time>`__ (UTC),
Thursday, 1 January 1970. Every day is treated as if it contains exactly
86400 seconds, so \ `leap
seconds <https://en.wikipedia.org/wiki/Leap_second>`__ are not applied
to seconds since the Epoch. In VES Epoch times are measured in
microseconds.

**Event.** A well-structured packet of network management information
identified by an eventName which is asynchronously communicated to one
or more instances of an Event Listener service to subscribers interested
in that eventName. Events can convey measurements, faults, syslogs,
threshold crossing alerts, and others types of information.

**Event Id**. Event key that is unique to the event source. The key must
be unique within notification life cycle similar to EventID from 3GPP.
It could be a sequential number, or a composite key formed from the
event fields, such as sourceName\_alarmCondition\_startEpoch. The
eventId should not include whitespace. For fault events, eventId is the
eventId of the initial alarm; if the same alarm is raised again for
changed, acknowledged or cleared cases, eventId must be the same as the
initial alarm (along with the same startEpochMicrosec and an incremental
sequence number.

**Event Name**. Identifier for specific types of events. Specific
eventNames registered by the YAML may require that certain fields, which
are optional in the Common Event Format, be present when events with
that eventName are published.

**Event Streaming**. The delivery of network management event
information in real time.

**Extensible Data Structures**. Data structures (e.g., hashMap) that
allow event sources to send information not specifically identified in
the VES schema.

**Hash Map**. A hash table, or data structure, used to implement an
associative array, a structure than can map keys to values. In VES 6.0,
all name-value pair structures were changed to hash maps (i.e., {‘name’:
‘keyName’, ‘value’: ‘keyValue’} was replaced with {‘keyName’:
‘keyValue’}).

**ICE**. Incubation and Certification Environment. Facilitates vendors
and third-party in developing virtual network functions using ONAP and a
network cloud.

**IPMI**. The `Intelligent Platform Management
Interface <https://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface>`__.

**JSON**. Java Script Object Notation. JSON is an
`open-standard <https://en.wikipedia.org/wiki/Open_standard>`__ `file
format <https://en.wikipedia.org/wiki/File_format>`__ that uses
`human-readable <https://en.wikipedia.org/wiki/Human-readable_medium>`__
text to transmit data objects consisting of `attribute–value
pairs <https://en.wikipedia.org/wiki/Attribute%E2%80%93value_pair>`__
and `array data types <https://en.wikipedia.org/wiki/Array_data_type>`__
(or any other
`serializable <https://en.wikipedia.org/wiki/Serialization>`__ value).
It is a very common `data <https://en.wikipedia.org/wiki/Data>`__ format
used for
`asynchronous <https://en.wikipedia.org/wiki/Asynchronous_I/O>`__
browser–server communication.

**NF**. Network Function. Generalized name for a VNF or PNF.

**NFC**. Network Function Component. Generalized name for a VNFC or a
component of a PNF.

**ONAP**. `Open Network Automation Platform <https://www.onap.org/>`__.

**PNF**. Physical Network Function.

**Policy**. Course of action for the management of the network. The ONAP
Policy Framework is a comprehensive policy design, deployment, and
execution environment. The Policy Framework is the ***decision making***
component in `an ONAP
system <https://www.onap.org/wp-content/uploads/sites/20/2017/12/ONAP_CaseSolution_Architecture_120817_FNL.pdf>`__.
It allows you to specify, deploy, and execute the governance of the
features and functions in your ONAP system, be they closed loop,
orchestration, or more traditional open loop use case implementations.
The Policy Framework is the component that is the source of truth for
all policy decisions.

**Reporting Entity Name**. Name of the entity reporting the event or
detecting a problem in another vnf/vm or pnf which is experiencing the
problem. May be the same as the sourceName. Not used for performance
measurements currently.

**SDC**. Service Design and Creation Platform: The ONAP visual modeling
and design tool. It creates internal metadata that describes assets used
by all ONAP components, both at design time and run time. The SDC
manages the content of a catalog, and assemblies of selected catalog to
define how and when VNFs are realized in a target environment.  

**Source Name**: Name of the entity experiencing the event issue, which
may be detected and reported by a separate reporting entity. The
sourceName identifies the device for which data is collected. A valid
sourceName must be inventoried in A&AI.

**Specific Problem**. Description of the alarm or problem.

**VES**. Virtual Function Event Stream. In 6.0, the definition of VES
was expanded to include event streaming for VNF, PNF and infrastructure.
The VES Event Listener can receive any event sent in the VES Common
Event Format.

**VES Event Listener**. A RESTful connectionless push event listener
capable of receiving single events or batches of events sent in the
Common Event Format.

**VM**. Virtual Machine.

**VNF**. Virtual Network Function. A VNF is a virtualized task formerly
carried out by proprietary, dedicated network hardware. (Examples:
virtual firewall, virtual DNS). A VNF can also be defined as a specific
kind of Vendor Software Product.

**YAML**. A `data serialization
language <https://en.wikipedia.org/wiki/Data_serialization_language>`__
and superset of JSON.

**VNFC**. Virtual Network Function Component. A VNFC is a part of a VNF.
It is a stand-alone executable that is loosely-coupled, granular,
re-usable, and responsible for a single capability.

It is intended to be defined separately by each provider implementing the VES Event Listener. The fields in internalHeaderFields are not provided by any event source but instead are added by the VES Event Listener service itself as part of an event enrichment process necessary for efficient internal processing of events received by the VES Event Listener"   |
