example 1

[0088] Example 1: Configure the early warning threshold of the receiving rate of an interface to be 10,000 packets per second, the early warning repair strategy is a user-defined script, the early warning re-detection strategy is the interface health detection strategy in the system, and the interface health detection strategy is built into the system script; during system operation, if the packet receiving speed of the interface exceeds the warning threshold, a failure warning will be triggered; according to the warning repair strategy, the packets received by the interface in the previous period will be analyzed, and the packets with the largest traffic will be restricted. Speed, the speed limit time can be customized. After the speed limit time passes, the packet receiving speed of the interface will be detected according to the health detection strategy. If the packet receiving rate is lower than the warning threshold within a period of time, the warning will be cleared, oth...

example 2

[0089]Example 2: The warning threshold of the overall CPU usage of the configuration system is 60%, the warning repair strategy is the system built-in script, and the warning re-detection strategy is the CPU health detection strategy in the form of the system built-in script; the overall CPU usage exceeds the 60%, trigger a fault warning; temporarily reduce the scheduling priority of several processes with the highest CPU usage in the system (except for critical processes in the system), and make statistics on the overall CPU usage of the system after waiting for the preset time , if it is lower than the warning threshold, cancel the fault warning, if it is still higher than the warning threshold, trigger the warning upgrade;

example 3

[0090] Example 3: The early warning threshold of the overall memory usage of the configuration system is 75%, the early warning repair strategy is a system built-in program, and the early warning re-detection strategy is a memory health detection strategy in the form of a system built-in script. When the overall memory usage rate exceeds 75% during system operation, a fault warning is triggered; and a warning repair strategy is triggered. In this example, the warning repair strategy is a garbage collection program, which cleans up unreferenced but unreleased memory in the system. After the garbage collection program finishes running, the overall memory usage of the system is detected. If it is lower than the warning threshold, the fault warning is cancelled, otherwise the warning is upgraded.

[0091] Such as Figure 4 Shown, be the flow chart of the preferred embodiment of the fault collection part of fault prevention and intelligent repair method in the network management sy...

Abstract

The invention relates to a fault preventing and intelligent repairing method and device for a network management system. The device comprises a fault detection module, a fault prevention module and a fault repairing module; and the method comprises the following steps of: setting corresponding early warning thresholds, fault thresholds, early warning repairing policies and fault repairing policies for system parameters related to faults in the network management system in advance; after monitoring, if the system parameters related to faults are more than or equal to the corresponding early warning thresholds and less than the corresponding fault thresholds, generating early warning messages, finding the corresponding early warning repairing policies and repairing the early warning; through monitoring, if the system parameters related to the faults are more than or equal to the corresponding fault thresholds, generating fault messages and reporting fault warning; and according to the fault messages, finding the corresponding fault repairing policies and repairing the faults. By adopting the fault preventing and intelligent repairing method and device which are disclosed by the invention, fault occurrence probability of the network management system is reduced to the greatest extent, and fault repairing speed is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a fault prevention and intelligent repair method and device in a network management system. Background technique [0002] In the fault management of the existing network management system, when a fault occurs in the system, the maintenance personnel are notified by means of an alarm, and the maintenance personnel perform manual intervention to solve the fault. [0003] This approach has several disadvantages: [0004] 1. It is always necessary to wait until the fault occurs before starting the fault repair, which will bring operational losses to the operator; [0005] 2. After a fault occurs, notify the network management through an alarm. By the time the maintenance personnel find the fault, the parameters of the device may have changed, so that the maintenance personnel may not be able to judge what happened when the fault occurred, so they may not be able to really find the problem....
