JSON Field | JSON sub-field | Description | Notes |
| { | |||
| domain | the domain datatype of the VES message | Must be measurementsForVfScaling | |
| metricsPerEventName | [ { | an array that describes parameters associating a closed loop flow to the policy governing this TCA instance | |
| eventName | a unique identifier that represents an event name that this TCA instance will act on | From VES 5.3 spec: "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." | |
| controlLoopSchemaType | this is a field which will be used to derive the schema of the Control Loop Event Message | Valid values for the Amsterdam release: VM | VNF | |
| policyScope | the scope of this policy message | ||
| policyName | a name identifying this policy message | ||
| policyVersion | a version identifying this policy message | ||
| thresholds | an array of one or more thresholds that are managed as part of a given closed loop | ||
| closedLoopControlName | the name that specifies which control loop this TCA instance is a part of | ||
| version | the version of the control loop | ||
| fieldPath | a value used to derive the metric within VES message that this TCA will apply to | expected to be part of a measurementsForVfScaling domain event message | |
| thresholdValue | the value of the metric which will trigger this threshold | must be numeric | |
| direction | |||
| severity | an identifier specifying the precendence of this threshold evalution; thresholds will be evaluated from highest severity (CRITICAL) to lowest (NORMAL); a given VES message will only trigger one threshold | expected values: CRITICAL | MAJOR | MINOR | WARNING| NORMAL | |
| closedLoopEventStatus | an identifier used to describe whether this threshold should be associated with a control loop ONSET action or whether it would describe a condition that indicates such a condition has ended (i.e. the condition has ABATED). Note that ABATED alerts will be correlated to ONSET events based on the following key fields. | expected values: ONSET | ABATED |

| ONAP TSC | Technical Steering Committee | This microservice was specifically developed for ONAP R0 and later enhanced for ONAP R1. Functionally, it has similarities to the cdap-mtca microservice used in 1707/1710 attECOMP however the code bases are different. |
