Virtualized Network Function Fault Management Interface (VNF FM) v1¶
Virtualized Network Function Fault Management Interface (VNF FM)¶
This interface manages the VNF fault management operations of VNF instances.
This interface allows the NFVO to invoke VNF fault management operations of VNF instances towards the VNFM. The detail of this interface is described in SOL002 v3.3.1 clause 7. The parameters of some specific standards need reference SOL013 v3.4.1 clause 5.
The GET method gets all alarms, Allow users to filter out alarms based on query parameter in the request.
If the API consumer intends to query all alarms, it sends a GET request to the “Alarms” resource. The VNFM returns a “200 OK” response to the API consumer, and includes zero or more data structures of type “Alarm” in the payload body.
An attribute selector allows the API consumer to choose which attributes it wants to be contained in the response. all_fields, fields, exclude_fields and exclude_default can be set as query parameters.
Attribute-based filtering expression. The following attribute names shall be supported by the Tacker in the attribute-based filtering expression: id, managedObjectId, rootCauseFaultyResource/faultyResourceType, eventType, perceivedSeverity, probableCause.

The GET method gets the alarm specified in the Tacker.
If the API consumer intends to read a particular alarm, it sends a GET request to the “Individual alarm” resource, addressed by the appropriate alarm identifier in its resource URI. The VNFM returns a “200 OK” response to the API consumer, and includes the data structure of type “Alarm” in the payload body. In case of failure, appropriate error information is provided in the response.

The GET method allows users to filter out subscriptions based on query parameter in the request.
If desired, e.g. to recover from an error situation, the API consumer can query information about its subscriptions by sending a GET request to the “Subscriptions” resource. In that case, the VNFM returns a “200 OK” response that contains the list of representations of all existing subscriptions that were created by the API consumer, and includes zero or more data structures of type “FmSubscription” in the payload body.
An attribute selector allows the API consumer to choose which attributes it wants to be contained in the response. all_fields, fields, exclude_fields and exclude_default can be set as query parameters.
Attribute-based filtering expression. The following attribute names shall be supported by the Tacker in the attribute-based filtering expression. All attribute names that appear in the FmSubscription and in data types referenced from it shall be supported by the VNFM in the filter expression. For example, below URI query parameter will match alarms with perceivedSeverity=WARNING

The GET method gets the subscription in the Tacker.
If desired, e.g. to recover from an error situation, the API consumer can read information about a particular subscription by sending a GET request to the resource representing that individual subscription. In that case, the VNFM returns a “200 OK” response that contains a representation of that individual subscription.
