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
can receive 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.

Compatibility with ONAP
~~~~~~~~~~~~~~~~~~~~~~~

Unless otherwise stated, this version of the Event Listener specification is
compatible with the release of ONAP the specification is released under.  In
other words, if the specification is released under the Frankfurt ONAP Release,
then the VES Event Collectors provided by DCAE will also be compatible with
the specification.

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 should start with a capital
letter and use camel-casing to separate words and acronyms. Acronyms
should 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
~~~~~~~~~~~~~~~~~~~~~~~~~~


eventId Examples:

**NOTE**: Please note, the following are only *examples*, and other formats
can be used provided they meet the requirement that the ``eventId`` is unique
for all events or unique fault occurrence.

**Example 1**: assumes a unique key for each domain consisting of domain
followed by an integer domain<n> or domainId<n>, where <n> is a positive integer,
e.g. fault000001, heartbeat000001, measurement000005,
notification3gppPerfFileReady0005

**Example 2**: assumes a unique integer key for all events across all domains
<n>: 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

      *    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.

      *    The eventId on Fault events is the same every time a given
           fault is raised (including onset and re-raise)

            1. The startEpochMicrosec value for the Fault event is the
               timestamp for when the fault onset occurs. Subsequent
               events for the same fault will keep the same startEpochMicrosec
               value.

            2. lastEpochMicrosec indicates the current event time. This value
               will be updated for each subsequent event for a given fault.

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

      *    After the fault is cleared, a new eventId is used.

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

   b. **Alternative Scenario**: Network Function When Fault Event Status is Not
      Maintained.

      *    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.

      *    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.

      *    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.

      *    lastEpochMicrosec indicates the current event time.

      *    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.

      *    Normally, a clear is expected for each fault to be sent from a
           network function. However a few fault notification types will never
           be re-raised or cleared. In this case, general rules for VES events
           shall be followed with a new eventId for each event and sequence
           number set to 0.

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.

Configuration Requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~
This section provides network function configuration requirements for
connectivity to a VES Event Listener via a RESTful API, using a VES JSON event.

There are several methods available to provide configuration settings to a
network function. This document does not specify the exact manner in which
the configuration elements described below must be required. The
configuration can be provided during instantiation (e.g. preload), provided by
an ONAP controller action, or provided manually.

* **VES Event Listener IP Addresses or FQDNs resolved via DNS**: Two FQDNs
  and/or IP Addresses are required. NF shall select one of the 2 FQDNs/IP
  Addresses for sending events and if the NF is unable to get an
  acknowledgement within predefined configurable time interval
  or unable to establish a TCP connection due inability to resolve DNS query or
  if the VES Event Listener is unresponsive, then the NF shall attempt to use
  the other FQDN/IP Address to connect to VES Event Listener to deliver the
  VES Events. The events shall only be sent to one VES Event Listener at a time.
  Please note: If a FQDN is used, the DNS query would return a single IP
  address.
* The active VES Event Listener (either the primary or secondary) will handle
  all VES events regardless of domain.
* **VES Credentials**: If the NF is using Basic Authentication, then the NF
  must support the provisioning of security and authentication parameters
  (HTTP username and password) in order to be able to authenticate with the
  VES Event Listener. The Username and Password should be set unique per NF
  instance and should be configured during the NF deployment through a
  Controller or other means. The same password must also be configured into VES
  Event Listener instance for successful handshake.
* **VES Heartbeat Interval**: This must be a configurable parameter; current
  default is 60 seconds. Note: the heartbeat interval should be greater than
  the ack timeout value.
* **Measurement Interval**: For measurement events, the measurement interval
  must be configurable and a default of 300 seconds.
* **ACK Timeout Interval**: Configurable, default 5 seconds.

Event Domain Requirements/Expectations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* **Heartbeat**: Heartbeat events must be sent to VES Event Listener based on
  configurable parameter.
* **Faults**: Fault events must be sent to the VES Event Listener as soon as
  they occur.
* **Measurements**: All measurement events must be sent at the configured
  measurementInterval. If the NF provides both application and GuestOS
  metrics, then they must both use the same measurementInterval.
* **Syslogs**: Syslog events should be sent to the VES Event Listener as soon as
  created, unless the NF is in debug mode (verbose logging enabled to get
  additional data to diagnose a problem), in which case the syslogs must be
  stored locally in the NF, for later access and possible secure transfer.
* **Pre-defined Events Formats (Domain: Mobile Flow, TCA, State Chang, etc)**:
  Other events (State change, TCA, Mobile Flow, etc) may use other pre-defined
  VES domains from the VES Common Event Format specification based on the role
  of the NF.
* **otherFields**: The otherFields Record defines fields for events belonging
  to the otherFields domain of the Technology Independent domain enumeration.
  This record provides a mechanism to convey a complex set of fields
  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.

Use of Collector FQDNs and/or IP Address
++++++++++++++++++++++++++++++++++++++++

* The NF must support two configurable endpoints for the VES Event Listener.
  One will be the active, primary event listener endpoint.  The other
  will be a standby event listener in the event the active endpoint is
  unavailable.
* When sending an event (FM, PM, Syslog, HB), the NF shall establish an HTTPS
  connection to one VES Event Listener FQDN/IP Address (if not already
  established) and send a VES event to it. Note that connections are not
  persistent. The events shall only be sent to only one VES Event Listener at a
  time.
* The NF must be able to detect that a VES Event Listener endpoint is
  unavailable, and trigger the fail-over to the backup endpoint. The mechanism
  for detecting unavailability must be configurable by the Service Operator
  (e.g. number of attempts, timeout value).
* If the NF is sending events to the VES Event Listener backup endpoint, then
  the NF must poll the primary endpoint on a configurable interval to check
  if the primary endpoint is now available. The NF may use the Heartbeat
  event or another mechanism to test availability.  If the primary endpoint
  becomes available, then the NF must fallback to the primary endpoint.
* A NF must only send a unique event to a single VES Event Listener endpoint
  at a time.  In other words, the NF must not send a duplicate event to the
  secondary endpoint unless the delivery to the primary endpoint failed.
* If both Primary and Secondary endpoints are not available, then the NF shall
  buffer the events locally. Refer to the Buffering of Events section for full
  details.
* If a NF is unable to establish a connection with a VES Event Listener or does
  not get an acknowledgement within a specified time, then it should log this
  failure and, optionally, send a fault event indicating
  connection/acknowledgement failure via the alternate FQDN/IP Address. The
  intent of this fault is to inform the Service Operator that the VES Event
  Listener endpoint has become unreachable by the NF.


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.

There are 2 methods of HTTP authentication supported: Certificate Authentication
and Basic Authentication.

Basic authentication is supported in VES Event Listener for backward
compatibility for existing NFs that are already managed by ONAP. New NFs should
support Certificate Authentication. Because the security is better, NFs may
choose to only support Certificate Authentication and not support Basic
Authentication.

Basic Authentication
~~~~~~~~~~~~~~~~~~~~

When using Basic Authentication, the event source must not pass credentials 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.

Mutual TLS Certificate Authentication
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When using Certificate Authentication, the event source 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>`__.
The event source must authenticate the VES Listener certificate and must
provide its own X.509v3 end-entity certificate to the VES Listener for
authentication. The Subject Name in the end-entity certificate must be used
according to `RFC5280 <https://www.ietf.org/rfc/rfc5280.txt>`__. If a
certificate is provided by the NF but it is invalid, the VES Listener is
expected to reject the connection and not fall back to basic authentication.

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

REST resources are defined with respect to a ServerRoot:

ServerRoot = https://{Domain|IP}:{Port}/{optionalRoutingPath}

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_30.1.1_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 should use camel casing to separate
   words and acronyms; only the first letter of each acronym shall be
   capitalized.

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.

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
   Listener API are defined below.

|                     |         | , which is defined in section 3          |

+---------------------+---------+------------------------------------------+

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: 1

-  X-PatchVersion: 1

-  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
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 7.1.1.

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, and re-transmit them once a connection has been
established.

The following events should be buffered:

* Faults with eventSeverity of ``MINOR``, ``MAJOR``, ``NORMAL``, or ``CRITICAL``
  with following expected behavior:

    * NF keeps a First-In-First-Out buffer.
    * Until the collectors are working again, it is desired that the NF sends
      the final state events only, and not intermediate ones. However, it is
      acceptable to buffer all events and send them over to the collector in
      the same order in which they were generated/received.

* When one VES Event Listener connectivity is re-established, NF should first
  send the buffered events and then start sending the new events.

    * Syslog with syslogSev of ``Emergency``, ``Alert``, ``Critical``,
      ``Error``, or ``Warning``

* All measurements events

publishEventBatch Requirements
******************************

Buffered events can be sent in batch using ``publishEventBatch``. However, a
NF vendor must only include multiple events for the same domain in the
``publishEventBatch``. The ``publishEventBatch`` event must also conform to
event size limits.

``publishEventBatch`` events are handled similarly to a single event. The
acknowledgement from the VES Event Listener is for the ``publishEventBatch`` and
not individual events within the ``publishEventBatch``.

Debug Mode
**********

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

.. _msg-size:

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

The maximum allowed message size is 2 megabytes of uncompressed text.
However,messages of this size have been known to cause performance and data
loss. It is strongly recommended,that messages not exceed 1 megabyte.
In a future version of the specification, a 1 megabyte limit will become
a mandatory requirement.

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

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

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

-  Supports only HTTPS access.

-  Uses the HTTP verb POST

-  Supports JSON content types

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

Call Flow

.. seqdiag::
    :caption: ``publishAnyEvent`` Call Flow

    seqdiag {
      edge_length = 250;
      client  -> listener [label = "POST /eventlistener/v7"];
      client <- listener [label = "HTTP 202 Accepted", note = "sync response"];
      === Error Scenario ===
      client  -> listener [label = "POST /eventlistener/v7"];
      client <- listener [label = "HTTP 4XX/5XX", note = "sync response"];

|               |          |          | ``username:password``. This string is |
|               |          |          | then Base64 encoded to produce the    |

Header Fields (note: all parameter names shall be treated as
case-insensitive):

+---------------+----------+----------+---------------------------------------+
| Parameter     | Data Type| Required?| Brief description                     |
+---------------+----------+----------+---------------------------------------+
| Accept        | string   | No       | Determines the format of the body of  |
|               |          |          | the response. Valid values are:       |
|               |          |          |                                       |
|               |          |          | -  application/json                   |
+---------------+----------+----------+---------------------------------------+
| Authorization | string   | No       | The username and password are formed  |
|               |          |          | into one string as "username:password"|
|               |          |          | . This string is then Base64 encoded  |
|               |          |          | to produce the encoded credential     |
|               |          |          | which is communicated in the header   |
|               |          |          | after the string "Authorization:      |

|               |          |          | Authorization header is missing, then |
|               |          |          | an HTTP 400 Invalid Request message   |
|               |          |          | shall be returned. If the string      |
|               |          |          | supplied is invalid, then an HTTP 401 |
|               |          |          | Unauthorized message shall be         |
|               |          |          | returned.                             |
+---------------+----------+----------+---------------------------------------+
| Content-length| integer  | No       | Note that content length is limited to|
|               |          |          | 2 megabyte (see :ref:`msg-size`).     |
+---------------+----------+----------+---------------------------------------+
| Content-type  | string   | Yes      | Must be set to one of the following   |
|               |          |          | values:                               |

|               |          |          | -  application/json                   |
+---------------+----------+----------+---------------------------------------+
| X-MinorVersion| integer  | No       | The minor version of the API requested|
|               |          |          | by the client                         |

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.

**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.

|           |         | -  command and commandList: created a list of command |
|           |         |    structures to enable the event collector to request|
|           |         |    changes of event sources. Commands consist of a    |
|           |         |    commandType along with optional fields (whose      |
|           |         |    presence is indicated by the commandType). Three   |
|           |         |    command types are currently supported:             |
|           |         |    'measurementIntevalChange',                        |

|           |         | -  eventDomainThrottleSpecificationList: removed this |
|           |         |    and replaced it with commandList.                  |
|           |         |                                                       |
|           |         | -  Operations and Sample Requests: modified the       |
|           |         |    operations and samples to support the new command  |
|           |         |    and commandList structures.                        |

|           |         |    meanRequestLatency. Updated the JSON schemas (now  |
|           |         |    v24) to match.                                     |

|           |         | -  6.5 provideThrottlingState operation: added the    |
|           |         |    Input Parameters section heading back and fixed the|
|           |         |    sample request to provide eventThrottlingState     |
|           |         |    (instead of eventThrottlingClientState).           |
|           |         |                                                       |

|           |         |       optional (although the internal Generic Event   |
|           |         |       Listener spec indicates, in the field           |
|           |         |       descriptions, that the AT&T enrichment process  |
|           |         |       shall ensure that these fields are populated)   |

|           |         |       present in the Word document                    |
|           |         |                                                       |

|           |         | -  Modified the Common Event Format JSON schema to    |
|           |         |    v27.0 to incorporate the above changes. Also, added|
|           |         |    the AT&T Copyright Notice from the top of the      |

|           |         |    heartbeatIntervalChange command; also corrected the|
|           |         |    spelling in the samples for the                    |

|           |         |       was replaced with ‘namedArrayOfFields’ in v28.0 |
