Datatypes
MonitoredData
The MonitoredData datatype identifies information to be monitored during the lifetime of a network service instance.
Attribute Name | Type | Mult. | Access | Stereotypes | Description |
vnfIndicatorInfo | VnfIndicatorData | 0..1 | RW | OpenModelAttribute
| Uniquely identifies the VNF Indicator class. One and only one of the attributes shall be included (i.e. there is a XOR relationship between the attributes). |
monitoringParameter | ? | 0..1 | RW | OpenModelAttribute
| Specifies the virtualised resource related performance metric to be monitored on an NS level or VNF level. One and only one of the attributes shall be included (i.e. there is a XOR relationship between the attributes). |
NsLifeCycleManagementScript
The LifeCycleManagementScript information element specifies a script for the NS.
Attribute Name | Type | Mult. | Access | Stereotypes | Description |
event | String | 1..* | RW | OpenModelAttribute
| Describes NS lifecycle event(s) or an external stimulus detected on an NFVO reference point. NOTE 1: A minimum set of NS lifecycle events triggered internally by the NFVO includes: start instantiation, end instantiation, start scaling, end scaling, start healing, end healing, start termination, end termination, start update, end update. NOTE 2: A minimum set of external stimulus includes: the receipt of request message of instantiation, scaling, healing, termination, update of NS. |
script | String | 1 | RW | OpenModelAttribute
| Includes an NS LCM script (e.g., written in a DSL) triggered to react to one of the events listed in the event attribute. |
VirtualLinkDf
