View-based network monitoring method and device

Abstract

The invention discloses a view-based network monitoring method, which comprises the steps as follows: respectively developing view strategy during normal operation of a network, on the point of fault generation and after the fault generation; constructing an entire network view, and on the basis of each sub-view generated in the entire network view during the normal operation of the network, developing monitoring strategy for each sub-view and monitoring the sub-view; during the normal operation of the network, when equipment in each sub-view is about to be faulty, based on the sub-view generated by the view strategy developed on the point of the fault generation, executing a preset fault treatment method and / or monitoring strategy for the sub-view; and during the normal operation of the network and on the point of the fault generation, when the equipment in each sub-view is faulty, executing a corresponding fault treatment method and / or monitoring strategy for faulty sub-view based on the new faulty sub-view generated by the view strategy after the fault generation. The invention further discloses a view-based network monitoring device. According to the invention, real-time fault monitoring data can be obtained, faults can be treated in real time, and monitoring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of network monitoring of IP networks, in particular to a view-based network monitoring method and device. Background technique [0002] Fault management is one of the five functional domains in the network management system standard. At present, most network management products are relatively primitive in the implementation of this functional domain. The method is to implement fault management through network devices actively sending Trap messages or network faults reported by Syslog logs. Trap messages are a type of message in the Simple Network Management Protocol SNMP, which are used by network devices to send messages to the network management platform. Syslog logs are system logs, which are used by network devices to send error or message logs to the log system. Trap messages and Syslog logs are both It is completely dependent on the active sending of network equipment. [0003] In network monitoring, ...

AI Technical Summary

Problems solved by technology

[0003] In network monitoring, network operation is divided into three stages: normal operation, imminent failure, and failure occurrence. In the existing fault management, when a failure is about to occur, the network management system will give a warning, but there is no follow-up action; After a fault occurs, the network management system will give an alarm and notify the network management personnel. If the fault cannot be resolved, the network management personnel will notify the equipment manufacturer to solve it. Whether it is the manufacturer or the network management personnel, basically only Trap messages and Syslog logs can be obtained. The solution is far from enough, because Trap messages and Syslog logs can only provide module-level monitoring information in network equipment, and do not record monitoring information in the peripheral environment, such as: information about related modules or information about other related devices; only in the upcoming When a fault occurs or a fault occurs, the monitoring information is sent, and the process data of the equipment is not recorded; only an alarm or warning is given, and there is no fault handling method

[0004] In the prior art, as a supplement to Trap messages and Syslog logs, some network management systems also monitor the status of devices by regularly obtaining data such as interfaces and ports of some network devices. It is difficult for personnel to predict the time and equipment of network failures, so they can only monitor all equipment in the entire network view, which will consume a lot of resources and a huge amount of data. a lot of work
