In one embodiment, a primary networking device in a branch network receives a notification of an anomaly detected by a secondary networking device in the branch network. The primary networking device is located at an edge of the network. The primary networking device aggregates the anomaly detected by the secondary networking device and a second anomaly detected in the network into an aggregated anomaly. The primary networking device associates the aggregated anomaly with a location of the secondary networking device in the branch network. The primary networking device reports the aggregated anomaly and the associated location of the secondary networking device to a supervisory device.
