Problems solved by technology

A single storage rule does not reflect priority
[0007] 3) Slow analysis speed: In an alarm storm, a large number of alarms will appear in an instant
It takes a long time to query the correlation rules one by one for each alarm, plus analyze the priority and recursion

Embodiment Construction

[0049] The basic idea of ​​the present invention is to first determine the corresponding relationship between the derivative alarm and all of its direct root cause alarms, and when there are more than two direct root cause alarms corresponding to the derivative alarm, determine the difference between the direct root cause alarms corresponding to the derivative alarm Based on these corresponding relationships, generate a weighted hierarchical directed graph between alarms, and generate a correlation matrix of alarms based on the weighted hierarchical directed graph. Because the correlation matrix clearly records the difference between the derived alarms and all the root cause alarms Therefore, for all alarms generated in the network, matching in the correlation matrix can determine the root cause alarm and its corresponding derived alarm.

[0050] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be fur...

Abstract

The invention discloses a method for determining an alarm correlation matrix, comprising the following steps of: determining the alarm correlation, wherein the correlation at least comprises derived alarm and the corresponding relationship of all direct root alarms and priority relationship between direct root alarms corresponding to the same derived alarm; generating a weighted layered directed graph of the alarm according to the alarm correlation; and generating the alarm correlation matrix according to the weighted alarm layered directed graph. The invention discloses a method for analyzing the alarm correlation simultaneously; based on the method, the analysis method also comprises the following steps of: as for the generated alarm, outputting the root alarm and the derived alarm in the generated alarms according to the matching situation between the generated alarm and the matrix element alarm of the line of the correlation matrix. The invention discloses a device for realizing the two methods simultaneously. The method and the device are more convenient and quicker to determine the root alarm and the derived alarm thereof.

Description

Technical field [0001] The present invention relates to alarm analysis technology, in particular to a method and device for determining an alarm correlation matrix, and a method and device for alarm correlation analysis using the alarm correlation matrix. Background technique [0002] The ever-increasing scale of the Internet and the continuous improvement of network transmission requirements are promoting the continuous advancement of communication technology. In the network of the communication system, when a certain physical device or software module is abnormal, an event report used to transmit fault information will be generated, and such an event report is an alarm. Since the network of the communication system is composed of many devices connected to each other, in the actual network operation, an abnormality of a component will cause a large number of network alarms, which is the so-called alarm storm. To locate and deal with faults in this large number of alarms, mainten...
