Alarm persistence method and alarm persistence device

Abstract

The invention discloses an alarm persistence method and an alarm persistence device. The alarm persistence method comprises steps that alarms are received; the types of the received alarms are determined, and the alarms are disposed in different alarm queues based on the different types; the alarms of the various alarm queues after a preset dormancy time period are converted into data formats, which can be received by a database; the alarms after the format conversion are stored in the database in a persistent way, and then problems such as the large pressure and the low performance of the data base caused by a single persistent alarming way in an alarm storm scene are solved; and at the same time, the switching of the persistence ways is realized based on the number of the received alarms in the preset time period, and the alarm persistence method is adapted to the various different conditions by considering the alarm persistency performance and a reliability requirement, and therefore the persistency reliability is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to an alarm persistence method and device. Background technique [0002] In the LTE (Long Time Evolution, long-term evolution) communication network, communication devices such as eNB (Evolved NodeB, evolved base station) will randomly report alarms to the network management system, and the network management will perform a series of processing on the alarms, and then persist the alarms into the database. [0003] Every time the network management system receives an alarm, it will open a database link, and based on the opened database link, the alarm will be persisted. After the alarm is persisted, the link will be released. [0004] Due to the alarm persistence method in the prior art, a database connection is opened for each alarm for persistence of the alarm, so there will be the following problems: [0005] 1. Each time a database connection...

AI Technical Summary

Problems solved by technology

[0005] 1. After obtaining a database connection each time, only one alarm can be persisted and then released. In the case of an alarm storm, it is necessary to obtain and release database connections frequently, which may lead to poor performance.

[0006] 2. In the alarm storm scenario, it will cause the problem of consuming a large number of database connections in an instant. Even if a fixed number of database connection pools are used, it will also cause a backlog of alarms in memory; if the duration is too long, too many alarm backlogs will cause Occupying a large amount of memory will cause low performance of the network management system and increase the probability of system problems

[0007] 3. In the scenario of alarm storm, the persistence of alarms will form a bottleneck, which will lead to real-time problems of alarms, and the alarms cannot be persisted to the database in real time

[0008] It can be seen that the methods in the prior art cannot well solve the problem of alarm persistence in the scene of alarm storm
