+VES Event Registration

+
+Introduction
+============
+
+This document specifies a YAML format for the registration of VES
+Events. The YAML format enables both human designers and applications to
+parse and understand the fields that will be sent by event sources in
+conjunction with specific types of events, which are identified by their
+eventNames.
+
+The semantics of the YAML format are easily extensible to accommodate
+processing needs that may arise in the future. Among the types of
+information specified in the YAML are field optionality, restrictions on
+field values, and event handling recommendations and requirements.
+
+This document should be read in conjunction with the VES Event Listener
+service specification, which defines the Common Event Format and
+introduces the concept of specific types of events, identified by
+eventNames.
+
+Audience
+--------
+
+This document is intended to support the following groups:
+
+- VNF Vendors
+
+- Service Provider (e.g., AT&T) Teams responsible for deploying VNFs
+ within their infrastructure
+
+VNF vendors will provide a YAML file to the Service Provider that
+describes the events that their VNFs generate. Using the semantics and
+syntax supported by YAML, vendors will indicate specific conditions that
+may arise, and recommend actions that should be taken at specific
+thresholds, or if specific conditions repeat within a specified time
+interval.
+
+Based on the vendor’s recommendations, the Service Provider may create
+another YAML, which finalizes their engineering rules for the processing
+of the vendor’s events. The Service Provider may alter the threshold
+levels recommended by the vendor, and may modify and more clearly
+specify actions that should be taken when specified conditions arise.
+The Service Provided-created version of the YAML will be distributed to
+Service Provider applications at design time.
+
+Goal
+----
+
+The goal of the YAML is to completely describe the processing of VNF
+events in a way that can be compiled or interpreted by applications
+across a Service Provider’s infrastructure, so that no additional human
+configuration or development is required beyond the creation of the YAML
+itself.
+
+Relation to the Common Event Format
+-----------------------------------
+
+The Common Event Format described in the VES Event Listener service
+specification defines the structure of VES events including optional
+fields that may be provided.
+
+Specific eventNames registered by the YAML (e.g., an InvalidLicense
+fault), may require that certain fields, which are optional in the
+Common Event Format, be present when events with that eventName are
+published. For example, a fault eventName which communicates an
+‘InvalidLicense’ condition, may be registered to require that the
+configured ‘licenseKey’ be provided as a name-value pair in the Common
+Event Format’s ‘additionalFields’ structure, within the ‘faultFields’
+block. Anytime an ‘InvalidLicense’ fault event is detected, designers,
+applications and microservices across the Service Provider’s
+infrastructure can count on that name-value pair being present.
+
+The YAML registration may also restrict ranges or enumerations defined
+in the Common Event Format. For example, eventSeverity is an enumerated
+string within the Common Event Format with several values ranging from
+‘NORMAL’ to ‘CRITICAL’. The YAML registration for a particular eventName
+may require that it always be sent with eventSeverity set to a single
+value (e.g., ‘MINOR’), or to a subset of the possible enumerated values
+allowed by the Common Event Format (e.g., ‘MINOR’ or ‘NORMAL’).
+
+Relation to Service Design and Creation
+---------------------------------------
+
+Event registration for a VNF (or other event source) is provided to the
+Service Provider’s Service Creation and Design Environment (e.g., SDC)
+as a set of two YAML files consisting of the vendor recommendation YAML
+and (optionally) the final Service Provider YAML. These YAML files
+describe all the eventNames that that VNF (or other event source)
+generates.
+
+Once their events are registered, the Service Creation and Design
+Environment can then list the registered eventNames (e.g., as a drop
+down list), for each VNF or other event source (e.g., a service), and
+enable designers to study the YAML registrations for specific
+eventNames. The YAMLs provide the information that the designers need to
+develop and understand policies, work flows and microservices that are
+triggered by those events. YAML registrations are both human readable
+and machine readable.
+
+The final Service Provider YAML is a type of Service Design and Creation
+‘artifact’, which is distributed to Service Provider applications at
+design time: notably, to applications involved in the collection and
+processing of VNF events. It is parsed by those applications so they can
+automatically support the receipt and processing of VNF events, without
+the need for any manual, VNF-specific development.
+
+YAML Files
+==========
+
+YAML Specification Conformance
+------------------------------
+
+YAML files should conform to version 1.2 of the YAML specification
+available at: http://yaml.org/spec/1.2/spec.html.
+
+Filename
+--------
+
+YAML file names should conform to the following naming convention:
+
+ {sdcModel}\_{sdcModelType}\_{v#}.yml
+
+The ‘#’ should be replaced with the current numbered version of the
+file.
+
+‘ASDC’ is a reference to the Service Provider’s Service Design and
+Creation environment. The sdcModelType is an enumeration with several
+values of which the following three are potentially relevant:
+
+- Service
+
+- Vnf
+
+- VfModule
+
+The sdcModel is the modelName of the specific modelType whose events
+are being registered (e.g., the name of the specific VNF or service as
+it appears in the the Service Design and Creation Environment).
+
+For example:
+
+- vMRF\_Vnf\_v1.yml
+
+- vMRF\_Service\_v1.yml
+
+- vIsbcSsc\_VfModule\_v1.yml
+
+File Structure
+--------------
+
+Each eventType is registered as a distinct YAML ‘document’.
+
+YAML files consist of a series of YAML documents delimited by ‘---‘ and
+‘…’ for example:
+
+::
+ ---
+
+ # Event Registration for eventName ‘name1’
+
+ # details omitted
+
+ ...
+
+ ---
+
+ # Event Registration for eventName ‘name2’
+
+ # details omitted
+
+ ...
+
+ ---
+
+ # Event Registration for eventName ‘name3’
+
+ # details omitted
+
+ ...
+
+YAML Syntax and Semantics
+=========================
+
+YAML registration documents show each relevant VES Common Event Model
+object and field (i.e., each element) for the eventName being
+registered, including any extensible fields (e.g., specific name-value
+pairs).
+
+Qualifiers
+----------
+
+Each object or field name in the eventName being registered is followed
+by a ‘qualifier’, which consists of a colon and two curly braces, for
+example:
+
+ “objectOrFieldName: { }”
+
+The curly braces contain meta-information about that object or field
+name (also known as the ‘element’), such as whether it is required to be
+present, what values it may have, what handling it should trigger, etc…
+
+Semantics have been defined for the following types of meta-information
+within the curly braces:
+
+Action
+~~~~~~
+
+The ‘action’ keyword may be applied to field values or to the event as a
+whole. The ‘action’ keyword specifies a set of actions that should be
+taken if a specified trigger occurs. For example, the ‘action’ keyword
+may specify that a threshold crossing alert (i.e., tca) be generated,
+and/or that a specific microservice handler be invoked, and/or that a
+specific named-condition be asserted. In the Rules section of the YAML
+file, tca’s and microservices may be defined on individual
+named-conditions or on logical combinations of named-conditions.
+
+The ‘action:’ keyword is followed by five values in square brackets. The
+first two values communicate the trigger, and the last three values
+communicate the actions to be taken if that trigger occurs:
+
+1. The first value conveys the trigger level. If the field on which the
+ action is defined reaches or passes through that level, then the
+ trigger fires. If a specific level is not important to the
+ recommended action, the ‘any’ keyword may be used as the first value.
+ (Note: ‘any’ is often used when an action is defined on the ‘event’
+ structure as a whole).
+
+2. The second value indicates the direction of traversal of the level
+ specified in the first value. The second value may be ‘up’, ‘down’,
+ ‘at’ or ‘any’. ‘any’ is used if the direction of traversal is not
+ important. ‘at’ implies that it traversed (or exactly attained) the
+ trigger level but it doesn’t matter if the traversal was in the up
+ direction or down direction. Note: If ‘up’, ‘down’ or ‘at’ are used,
+ the implication is that the microservices processing the events
+ within the service provider are maintaining state (e.g., to know that
+ a measurement field traversed a trigger level in an ‘up’ direction,
+ the microservice would have to know that the field was previously
+ below the trigger level). When initially implementing support for
+ YAML actions, a service provider may choose to use and interpret
+ these keywords in a simpler way to eliminate the need to handle
+ state. Specifically, they may choose to define and interpret all ‘up’
+ guidance to mean ‘at the indicated trigger level or greater’, and
+ they may choose to define and interpret all ‘down’ guidance to mean
+ ‘at the indicated trigger level or lower’.
+
+3. The third value optionally names the condition that has been attained
+ when the triggers fires (e.g., ‘invalidLicence’ or
+ ‘capacityExhaustion’). Named-conditions should be expressed in upper
+ camel case with no underscores, hyphens or spaces. In the Rules
+ section of the YAML file, named-conditions may be used to specify
+ tca’s that should be generated and/or microservices that should be
+ invoked. If it is not important to name a condition, then the keyword
+ ‘null’ may be used as the third value.
+
+4. The fourth value recommends a specific microservice (e.g., ‘rebootVm’
+ or ‘rebuildVnf’) supported by the Service Provider, be invoked if the
+ trigger is attained. Design time processing of the YAML by the
+ service provider can use these directives to automatically establish
+ policies and configure flows that need to be in place to support the
+ recommended runtime behavior.
+
+ If a vendor wants to recommend an action, it can either work with
+ the service provider to identify and specify microservices that the
+ service provider support, or, the vendor may simply indicate and
+ recommend a generic microservice function by prefixing ‘RECO-’ in
+ front of the microservice name, which should be expressed in upper
+ camel case with no underscores, hyphens or spaces.
+
+ The fourth value may also be set to ‘null’.
+
+1. The fifth value third value indicates a specific threshold crossing
+ alert (i.e., tca) that should be generated if the trigger occurs.
+ This field may be omitted or provided as ‘null’.
+
+ Tca’s should be indicated by their eventNames.
+
+ When a tca is specified, a YAML registration for that tca eventName
+ should be added to the event registrations within the YAML file.
+
+Examples:
+
+- event: { action: [ any, any, null, rebootVm ] }
+
+ # whenever the above event occurs, the VM should be rebooted
+
+- fieldname: { action: [ 80, up, null, null, tcaUpEventName ], action:
+ [ 60, down, overcapacity, null ] }
+
+ # when the value of fieldname crosses 80 in an up direction,
+ tcaUpEventName
+
+ should be published; if the fieldname crosses 60 in a down direction
+ an
+
+ ‘overCapacity’ named-condition is asserted.
+
+Array
+~~~~~
+
+The ‘array’ keyword indicates that the element is an array; ‘array:’ is
+following by square brackets which contain the elements of the array.
+Note that unlike JSON itself, the YAML registration will explicitly
+declare the array elements and will not communicate them anonymously.
+
+Examples:
+
+- element: { array: [
+
+ firstArrayElement: { },
+
+ secondArrayElement: { }
+
+ ] }
+
+Default
+~~~~~~~
+
+The ‘default’ keyword specifies a default field value. Note: the default
+value must be within the range or enumeration of acceptable values.
+
+Examples:
+
+- fieldname: { range: [ 1, unbounded ], default: 5 }
+
+- fieldname: { value: [ red, white, blue ], default: blue }
+
+HeartbeatAction
+~~~~~~~~~~~~~~~
+
+The ‘heartbeatAction’ keyword is provided on the ‘event’ objectName for
+heartbeat events only. It provides design time guidance to the service
+provider’s heartbeat processing applications (i.e., their watchdog
+timers). The syntax and semantics of the ‘heartbeatAction’ keyword are
+similar to the ‘action’ keyword except the trigger is specified by the
+first field only instead of the first two fields. When the
+‘heartbeatAction’ keyword is indicated, the first field is an integer
+indicating the number of successively missed heartbeat events. Should
+that trigger occur, the remaining fields have the same order, meaning
+and optionality as those described for the ‘action’ keyword.
+
+Examples:
+
+- event: { heartbeatAction: [ 3, vnfDown, RECO-rebootVnf, tcaEventName
+ ] }
+
+ # whenever the above event occurs, a vnfDown condition is asserted
+ and the vnf should be rebooted, plus the indicated tca should be
+ generated.
+
+Presence
+~~~~~~~~
+
+The ‘presence’ keyword may be defined as ‘required’ or ‘optional’. If
+not provided, the element is assumed to be ‘optional’.
+
+Examples
+
+- element: { presence: required } # element must be present
+
+- element: { presence: optional } # element is optional
+
+- element: { value: blue } # by omitting a presence definition, the
+
+ element is assumed to be optional
+
+Range
+~~~~~
+
+The ‘range’ keyword applies to fields (i.e., simpleTypes); indicates the
+value of the field is a number within a specified range of values from
+low to high (inclusive of the indicated values). . ‘range:’ is followed
+by two parameters in square brackets:
+
+- the first parameter conveys the minimum value
+
+- the second parameter conveys the maximum value or ‘unbounded’
+
+The keyword ‘unbounded’ is supported to convey an unbounded upper limit.
+Note that the range cannot override any restrictions defined in the VES
+Common Event Format.
+
+Examples:
+
+- fieldname: { range: [ 1, unbounded ] }
+
+- fieldname: { range: [ 0, 3.14 ] }
+
+Structure
+~~~~~~~~~
+
+The ‘structure’ keyword indicates that the element is a complexType
+(i.e., an object) and is followed by curly braces containing that
+object.
+
+Example:
+
+- objectName: { structure: {
+
+element1: { },
+
+element2: { },
+
+anotherObject: { structure: {
+
+element3: { },
+
+element4: { }
+
+} }
+
+} }
+
+Units
+~~~~~
+
+The ‘units’ qualifier may be applied to values provided in VES Common
+Event Format extensible field structures. The ‘units’ qualifier
+communicates the units (e.g., megabytes, seconds, Hz) that the value is
+expressed in. Note: the ‘units’ should not contain any space characters
+(e.g., use ‘numberOfPorts’ or ‘number\_of\_ports’ but not ‘number of
+ports’).
+
+Example:
+
+- field: { structure: {
+
+ name: { value: pilotNumberPoolSize },
+
+ value: { units: megabytes } # the value will be expressed in
+ megabytes
+
+ } }
+
+Value
+~~~~~
+
+The ‘value’ keyword applies to fields (i.e., simpleTypes); indicates a
+single value or an enumeration of possible values. If not provided, it
+is assumed the value will be determined at runtime. Note that the
+declared value cannot be inconsistent with restrictions defined in the
+VES Common Event Format (e.g., it cannot add an enumerated value to an
+enumeration defined in the Common Event Format, but it can subset the
+defined enumerations in the Common Event Format).
+
+Values that are strings containing spaces should always be indicated in
+single quotes.
+
+Examples:
+
+- fieldname: { value: x } # the value is ‘x’
+
+- fieldname: { value: [ x, y, z ] } # the value is either ‘x’, ‘y’, or
+ ‘z’
+
+- fieldname: { presence: required } # the value will be provided at
+ runtime
+
+- fieldname: { value: ‘error state’ } # the value is the string within
+ the single quotes
+
+Rules
+-----
+
+Rules Document
+~~~~~~~~~~~~~~
+
+After all events have been defined, the YAML file may conclude with a
+final YAML document delimited by ‘---‘ and ‘…’, which defines rules
+based on the named ‘conditions’ asserted in action qualifiers in the
+preceding event definitions. For example:
+
+::
+ ---
+
+ # Event Registration for eventName ‘name1’
+
+ event: {presence: required, action: [any, any, A, null], structure:
+ {
+
+ # details omitted
+
+ }}
+
+ ...
+
+ ---
+
+ # Event Registration for eventName ‘name2’
+ event: {presence: required, structure: {
+ commonEventHeader: {presence: required, structure: {
+ # details omitted
+ }}
+
+ measurementsForVfScalingFields: {presence: required, structure: {
+ cpuUsageArray: {presence: required, array: {
+ cpuUsage: {presence: required, structure: {
+ cpuIdentifier: {presence: required},
+ percentUsage: {presence: required, action: [90, up, B, null]}
+ }}
+ }},
+ # details omitted
+ }}
+ }}
+ ...
+ ---
+ # Rules
+ rules: [
+
+ # defined based on conditions ‘A’ and ‘B’ - details omitted
+
+ ]
+
+ ...
+
+Rules Syntax and Semantics
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The YAML ‘rules’ document begins with the keyword ‘rules’ followed by a
+colon and square brackets. Each rule is then defined within the square
+brackets. Commas are used to separate rules.
+
+Each rule is expressed as follows:
+
+rule: {
+
+trigger: *logical expression in terms of conditions*,
+
+microservices: [ *microservice1, microservice2, microservice3…* ]
+
+alerts: [tcaE*ventName1, tcaEventName2, tcaEventName3…* ],
+
+}
+
+Notes:
+
+- All referenced tcaEventNames should be defined within the YAML.
+
+- For information about microservices, see section 3.1.1 bullet number
+ 4.
+
+- At least one microservice or alert should be specified, and both
+ microservices and alerts may be specified.
+
+Simple Triggers
+~~~~~~~~~~~~~~~
+
+The trigger is based on the named ‘conditions’ asserted in the action
+qualifiers within the event definitions earlier in the YAML file. The
+following logical operators are supported:
+
+- &: which is a logical AND
+
+- \|\|, which is a logical OR
+
+In addition parentheses may be used to group expressions.
+
+Example logical expression:
+
+ (A & B) \|\| (C & D)
+
+Where A, B, C and D are named conditions expressed earlier in the YAML
+file.
+
+Example rules definition:
+
+::
+ rules: [
+ rule: {
+ trigger: A,
+ alerts: [tcaEventName1],
+ microservices: [rebootVm]
+ },
+ rule: {
+ trigger: B \|\| (C & D),
+ microservices: [scaleOut]
+ }
+ ]
+
+Note: when microservices are defined in terms of multiple event
+conditions, the designer should take care to consider whether the target
+of the microservice is clear (e.g., which VNF or VM instance to perform
+the action on). Future versions of this document may provide more
+clarity.
+
+Time Based Qualifiers
+~~~~~~~~~~~~~~~~~~~~~
+
+Time based rules may be established by following any named condition
+with a colon and curly braces. The time based rule is placed in the
+curly braces as follows:
+
+::
+ trigger: B:{3 times in 300 seconds}
+
+This means that if condition B occurs 3 (or more) times in 300 seconds
+(e.g., 5 minutes), the trigger fires.
+
+More complex triggers can be created as follows:
+
+::
+ trigger: B:{3 times in 300 seconds} \|\| (C & D:{2 times in 600 seconds}),
+
+This means that the trigger fires if condition B occurs 3 (or more)
+times in 5 minutes, OR, if condition D occurs 2 (or more) times in 10
+minutes AND condition C is in effect.
+
