Virtualized Network Function Performance Management Interface (VNF PM) v2

Virtualized Network Function Performance Management Interface (VNF PM)

This interface manages the VNF performance management operations of VNF instances.

This interface allows providing performance management (measurement results collection and notifications) related to VNFs. The detail of this interface is described in SOL002 v3.3.1 clause 6. The parameters of some specific standards need reference SOL013 v3.4.1 clause 5.

POST
/vnfpm/v2/pm_jobs

Create a PM job (v2)

The POST method creates a new PM job. PM jobs group details of performance collection and reporting information.

As the result of successfully executing this method, a new PM job shall have been created, and return detailed PM job data. In case of failure, including an invalid notification endpoint, appropriate error information is provided in the response.
