8.8. Service: VES Event Listener 5.4.1

Table of Contents

8.9. 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.

8.10. 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.

8.11. 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).

8.12. 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.

8.13. 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.

8.14. Security

Event sources must identify themselves to the VES Event Listener.

Event source credentials are passed using HTTP Basic Authentication.

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.

8.51. 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.

Field Name

Data Type

Required?

Description

messageId

xs:string

Yes

Unique message identifier of the format ‘ABCnnnn’where ‘ABC’is either ‘SVC’for Service Exceptions or ‘POL’for Policy Exception.

Exception numbers may be in the range of 0001 to 9999 where :

text

xs:string

Yes

Message text, with replacement variables marked with %n, where n is an index into the list of <variables> elements, starting at 1

variables

xs:string [0..unbounded]

No

List of zero or more strings that represent the contents of the variables used by the message text.

url

xs:anyUrl

No

Hyperlink to a detailed error resource (e.g., an HTML page for browser user agents).

8.52. 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

8.53. 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.

Verb

publishAnyEvent

POST

/eventListener/v{apiVersion}

publishEventBatch

POST

/eventListener/v{apiVersion}/eventBatch

Table - REST Operation Summary

8.54.2. 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).

8.54.3. 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).

8.55. Operation: publishAnyEvent

8.55.1. 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

400

Bad Request

Many possible reasons not specified by the other codes (e.g., missing required parameters or incorrect format). The response body may include a further exception code and text. HTTP 400 errors may be mapped to SVC0001 (general service error), SVC0002 (bad parameter), SVC2000 (general service error with details) or PO9003 (message content size exceeds the allowable limit).

401

Unauthorized

Authentication failed or was not provided. HTTP 401 errors may be mapped to POL0001 (general policy error) or POL2000 (general policy error with details).

404

Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

405

Method Not Allowed

A request was made of a resource using a request method not supported by that resource (e.g., using PUT on a REST resource that only supports POST).

500

Internal Server Error

The server encountered an internal error or timed out; please retry (general catch-all server-side error).HTTP 500 errors may be mapped to SVC1000 (no server resources).
