System, device and method for filtering warning information

Abstract

The invention discloses a system, a device and a method for filtering warning information used for a network management system; the warning information filtering system comprises a warning acquisition module, a warning filtering module, a warning buffer and a warning processing module, wherein the warning acquisition module is used for acquiring and sending the warning information to the warning filtering module; the warning filtering module is used for storing the received warning information; if warning disappearing information is received and then warning generation information with same warning is received in the set time, the warning generation information and the warning appearing information which have the same warning are deleted; the warning buffer is used for buffering the warning information filtered by the warning filtering module; and the warning processing module is used for extracting the warning information from the warning buffer and processing the warning information. The technical proposal can effectively reduce the warning number needing buffering, thus reduce the disk space used for storing the warning, reduce the impact of warning storm on CPU and improve the utilization ratio of the system.

Description

technical field [0001] The invention relates to network management technology, in particular to an alarm information filtering system, device and method. Background technique [0002] In the network, collecting and processing the alarm information generated by the network is an important function of the network management system in the network. Under normal circumstances, the number of alarm information generated by the network per unit time will not be very large. However, when the network scale is large and some specific faults occur, the network may generate a large number of alarm information in a short period of time and report To the network management system in the network, reporting a large amount of alarm information in a short period of time is called an alarm storm. [0003] Alarm storms can have many negative effects. For example: limited by the processing speed of the network management system, the alarm information reported to the network management system ma...

Problems solved by technology

But its disadvantage is that although the alarms are cached, the total number of alarms processed by the network management system has not been reduced. , also need to be saved to the database and take up a lot of disk space

[0010] In the process of realizing the present invention, the inventor found that a considerable part of the alarms generated by the network management will frequently report alarm generation and alarm disappearance, such as performance over-limit alarms. When fluctuating, alarm generation and alarm disappearance reports will occur frequently. At this time, the number of alarm disappearances is of no practical significance to users. waste
