Abstract: A root cause failure determining method and an apparatus are provided. The method includes a first network element determines alarm information of N objects, where N is an integer greater than or equal to 2, and the first network element determines a root cause failure of the alarm information of the N objects based on an object association relationship, where the root cause failure is alarm information of M objects in the N objects, where M is a positive integer less than or equal to N. A root cause failure of a plurality of pieces of alarm information can be determined, and a service ticket can be dispatched for the root cause failure to reduce operation and maintenance costs.

Abstract: An alarm analysis method, including determining M alarm pairs in a first alarm set, where each alarm pair of the M alarm pairs includes a first alarm and a second alarm having an association, generating, according to an association rule, a first feature set of N alarm pairs, the first alarm of each alarm pair of the N alarm pairs being an alarm pair root in the first feature set, the first feature set including a first probability that a first subsystem to which each first alarm belongs is a subsystem root and a first alarm object is an alarm object root and a second probability that a second subsystem to which each second alarm belongs is a subsystem root and a second alarm object is an alarm object root, and determining root information of the first alarm set based on the first probability and the second probability.
