<p>A method for analyzing alarm data and a system thereof are disclosed. The method, which is applied in a system having a peer-to-peer model indicating connection relation of network elements, includes: dividing a complete dataset of historical alarms into a plurality of alarm subsets according to network element types and alarm reasons (S101); combining any two divided alarm subsets, and calculating support degree of two alarm subsets in each kind of combination within the complete dataset of historical alarms (S102); if the support degree larger than a first threshold, according to each alarm subset of these two alarm subsets, calculating conditional probabilities of present of alarms in another alarm subsets in the simultaneous present of alarms in each alarm subset, respectively (S103); if the conditional probability larger than a second threshold, determining that alarms in the alarm subset, which function as conditions, are root alarms with respect to alarms in another alarm subsets (S104).</p> |
