Abstract
An alarm root cause analyzing method includes: obtaining at least one alarm of a managed network; sending an alarm raising time to a failed link locating device; receiving an identifier of a failed link, an identifier of an affected edge device, and an identifier of a device interface of the affected edge device; querying whether any alarm from the failed link exists in the at least one alarm, if an alarm from the failed link exists, marking the alarm from the failed link as a root cause alarm; querying whether any alarm from the affected edge device exists in the at least one alarm, if an alarm from the affected edge device exists, if a service object corresponding to the alarm from the affected edge device is borne over the device interface of the affected edge device, marking the alarm from the affected edge device as a derivative alarm.
