Threshold expression analytic method

Abstract

The method stores expression of threshold value in advance, and builds Map, which stores coincidence relation between ME name and value of measure entity in report of collected data. The method includes following steps: (1) reading out expression of threshold value stored; (2) picking up ME name of measure entity in expression of threshold value one by one; looking up value corresponding to ME name in the said Map by using ME name as index; replacing corresponding ME name in expression of threshold value by using looked up value; (3) based on replaced expression of threshold value, determining whether parsed result of expression of threshold value is true or false. The invention raises speed of parsing expression.

Description

technical field

[0001] The invention relates to a network management system (NMS) technology, in particular to a threshold expression analysis method in the NMS. Background technique

[0002] As the name implies, the function of NMS is to manage network devices and network lines. Through the network management system, the available time of the network can be greatly increased, the utilization rate of network units, network performance, service quality, security and economic benefits can be improved, and the management and control network operation can be reduced in a multi-standard and multi-vendor mixed network environment. cost and provide the basis for network planning.

[0003] During network operation, the performance data of each network element has its own performance threshold. Specifically, the performance threshold refers to the boundary conditions set by the user in the form of logical expressions for a specific measurement object (MO). Usually, this logical ex...
