Copyright 2017 Huawei Technologies Co., Ltd. +====================== +VES Event Registration +====================== + +.. contents:: Table of Contents + +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. + +YAML Examples +============= + +An example YAML file is provided below which registers some events for a +vMRF VNF.
