A software defined network (SDN) can add network repository functions (NRF) into a configurations database to enable NF discovery. The SDN can subscribe to NRF notifications to receive new cloud native functions (CNF), registrations, or any other update to the CNF status in 5G system. In addition to listening to NRF notifications, the SDN can implement CNF pooling processes to periodically retrieve CNF from an NRF repository and stay in sync with 5G systems. Thus, a deep service path discovery can be developed from network service configurations and container call flows to enable an accurate alarm correlation and troubleshooting for the operations. This service path deep discovery can be designed and implemented as a standalone system or in an SDN framework with integration of a container management framework such as K8 kubernetes.
