...

• • • • 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.
