Service: *VES Event Listener*
=============================

.. contents:: Table of Contents

Introduction
============

This document describes the RESTful interface for the VES (Virtual function Event Streaming) Event Listener. The VES Event Listener is capable of receiving any event sent in the VES Common Event Format. The Common Event Format is a JSON structure consisting of a required Common Event Header Block accompanied by zero or more event domain blocks. A JSON Schema of the VES Common Event Format is provided in Section 4 of this document.

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 others 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}\_{SdcModel or
    ApplicationPlatform}\_{DescriptionOfInfoBeingConveyed}

Domain abbreviations are derived from the 'domain' field in the
commonEventHeader, as specified below:
-  'Fault'for the fault domain
-  'Heartbeat'for the heartbeat domain
-  'Mfvs'for the measurementsForVfScaling domain
-  'MobileFlow'for the mobileFlow domain
-  'Other'for the other 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

Sdc (the ONAP Service Design and Creation environment) defines and catalogs specific services, VNFs, VF modules and other entities, which are generically referred to as 'Sdc models'. The Sdc model that an event is associated with should be indicated in the second subfield within the eventName. If the event is not associated with an Sdc model but is instead being generated by an application platform like SO, then a string identifying the  Application Platform may be used instead. In either case, all subfield names should be converted to camel case format (with no spaces, hyphens or underscores).

The final subfield of the eventName name should describe, in a compact camel case format (with no spaces, hyphens or underscores), the specific information being conveyed by the event. In some cases, this final subfield will not be required (e.g., in the case of Heartbeats or in the case of an event source which, for a domain like syslog, defines only one eventName to support it):

Examples of eventNames following the naming standards are provided below:

-  Fault\_MobileCallRecording\_PilotNumberPoolExhaustion
-  Heartbeat\_vIsbcMmc
-  Other\_WanBonding\_InstantiationPart1Complete
-  Syslog\_vDbe
-  Tca\_vDbe\_CpuThresholdExceeded
-  Other\_SO\_InstantiationPhase1Complete

Any questions about the naming of eventNames should be resolved as part of service and resource onboarding to the ONAP Service Design and Creation environment (i.e., Sdc).

Support for Protocols Other Than HTTPS
--------------------------------------

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

Alternative specifications may be provided in future using Websockets, which would establish a permanent TCP socket, or Apache Avro which provides a binary format over an RPC protocol to be defined. Both would leverage the JSON schema provided in this document.

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. Note that the major number appears in REST resource URLs as v# (where '#'is the major number).

-  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.

-  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.

Security
========

Event sources must identify themselves to the VES Event Listener.

Event source credentials are 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.

Examples are provided below.

Exceptions
==========

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.

Table - REST Operation Summary

Api Version
~~~~~~~~~~~

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: clients of
older versions will break 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).

Commands Toward Event Source Clients
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Note: Vendors are not currently required to implement support for
command processing; in addition, command processing may be supported by
an App-C interface in future.

This specification supports commands from event consumers back toward
event source clients. This enables the event consumer (e.g., AT&T event
collectors) to command event sources to change their measurement
intervals or throttle the information they are sending to the event
consumer. Note that commands are sent as part of the synchronous
response to events sent by the event source toward the event consumer.
This is done so that the event source does not need to host a service to
listen for commands from events consumers. The following commands are
currently supported:

+-----------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| **Command**                 | **Description**                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |

| throttlingSpecification     | Commands the event source to throttle events as specified by the provided eventDomainThrottlingSpecification. This specification identifies the fields to suppress within the domain and even supports identification of subfields to suppress within objects or name-value pair structures. Note that required fields should not be suppressed and may result in errors being thrown by the event consumer back toward the event source when events without the required fields are sent to the event consumer.

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.

During such an outage, only the following events should be buffered:

-  Faults with eventSeverity of "MINOR", "MAJOR" or "CRITICAL"

-  Syslogs with syslogSev of 0-5

-  All MeasurementsForVfScaling events

VNFs 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 VNF 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).

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

-  Allows the event collector to use the HTTP response to command the
   event source to throttle event messages it may send in the future.

Operation: publishEventBatch
----------------------------

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

-  Allows the event collector to use the HTTP response to command the
   event source to throttle event messages it may send in the future.
