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.
