ONAP Control Loops require an APPC HealthCheck solution that provides a means of performing VNF and VM level checks. Additionally, the HealthCheck response provided back to the APPC LCM API client needs to contain a payload that with details on what and why the HealthCheck failed. Currently, the APPC HealthCheck is only at the VNF Level and only returns a Success or Failure code.
One useful example of this enhanced functionality is the case where a VNF that contains for instance eight VMs. The VNF level HealthCheck may find that seven out of the eight VMs are operating satisfactorily but one VM failed the HealthCheck. The state along with the indication of which VM(s)/VNFC(s) failed and why the HealthCheck failed will be returned to the APPC LCM Clientclient. The details on returned for the failed VM(s)/VNFC(s) will allow the decision/policy manager to make a determination on whether or not to restart the one VM/VNFC or all VM(s)/VNFC(s) contained in the VNF.
