A system, method, and computer-readable medium for detecting errors on a network. According to a preferred embodiment of the present invention, a network error manager retrieves a network topology from a master subnet manager, wherein the network includes a collection of devices coupled by a first interconnect type. When a connectivity failure is detected in the first interconnect type, the network error manager receives from the master subnet manager at least one event notification via a second interconnect type. An error log analysis component identifies at least one device among the collection of devices as a possible cause of the connectivity failure in the first interconnect type. The network error manager retrieves events from at least one device among the collection of devices that can influence a state of the first interconnect type.
