VMware Telco Cloud Service Assurance NFV-SOL collector receives the status information of Samsung vDU components like CUCP, CUUP, and DU by polling USM REST API for every polling period. The status of these objects are updated in real-time.

Based on the status value, an event called Impaired is triggered on CUCP, CUUP, and DU objects.

For Samsung vDU USM Topology Map and RCA, see the Samsung vDU USM use-case section in the VMware Telco Cloud Service Assurance User Guide.
