Level HealthCheck

• Request:

...

• • Will conform to the APPC LCM VNF Level Request format per the APPC LCM API Guide.

...

• • The HealthCheck API will perform LCM request validations.

...

• • • IF

      • VNF specific HealthCheck is available on the VNF, execute the VNF HealthCheck on the VNF:

1. 1. 1. 1. 1. Connect to the VNF via (REST, Chef or Ansible) via the endpoint configured in the APPC CDT Tool.
            2. Initiate the VNF HealthCheck on the VNF.

• • • ELSE:
      • APPC will obtain VNF details from A&AI
        1. Including:
           1. vserver details in order to enable checking each VM/VNFC in the VNF

...

• • • • 2. APPC performs HealthCheck on each vserver via Cloud Provider API
           1. Obtain Cloud Provider details.
           2. Connect to the Cloud Provider for each VM/VNFC
              1. I.e. for OpenStack Compute API:
                 1. Show Server Details
                 2. /servers/{server_id} /“OS-EXT-STS:vm_state”
              2. Mark VM/VNFC Failed marking the state.
              3. If any state other than “active” the HealthCheck for the VM/VNFC will be marked failed.
        3. IF ANY VM/VNFC is in a failed state the overall HealthCheck of the VNF will return failed along with the failure reason in the HealthCheck response payload.

• Response:

...

• • VNF level HealthCheck response will:

1. 1. Conform to the APPC LCM Response format per the APPC LCM API Guide.
   2. Return Failed status code as well as status code message (APPC LCM Response includes a “status” section with subsections of “code” and “message.”
