Presented herein is an “On-Device Expert System” for implementation at devices operating in accordance with Connectivity Fault Management (CFM). In particular, in addition to fault detection/verification/notification, the techniques presented herein now enable fault device/link identification. The “On-Device Expert System” performs telemetry operations inside the device itself, instead of having the same operations performed in a controller. As such, the techniques presented herein avoid the need for multiple resources usage in the controller for the same telemetry details. With the “On-Device Expert System” providing the needed telemetry details to the controller, the controller now can directly trigger the application associated with a received telemetry message and perform the remedial/enhancement/notification needed for the networks.
