<p>A method and device for generating an alarm association graph, and a method and device for determining association alarms are disclosed. The method for generating an alarm association graph includes the following steps: determining successively two topologic nodes connected physically according to a network equipment topologic graph; acquiring all the alarms currently contained in the two topologic nodes respectively, and searching the alarms therein having association relationships; classifying the alarms having association relationships according to alarm properties, and generating an alarm collection for each alarm type; determining that an association relationship exists between the alarm collection of a first alarm type and the alarm collection of a second alarm type when the calculated probability of the occurrence of the association relationship between the alarm collection of the first alarm type and the alarm collection of the second alarm type, exceeds a first preset probability value,, and displaying the association relationship on the alarm association graph. The method could reflect the association relationships between the alarms simply and directly, and not be restricted to the network size, and be extended easily.</p> |
