Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0035] In order to solve the problem in the existing expression parsing process that the expression with an operator in the operand cannot be correctly parsed, the present invention provides an expression parsing method. Operands in this expression that previously included operators were replaced with alternative names that did not include operators that the Threshold Management System recognized. In this way, during the subsequent legality check and conversion from the forward expression to the subsequent expression, the threshold management system can correctly identify the substituted operands in the expression, thereby completing the legality check of the expression and the conversion of the preceding expression. The conversion of the expression to the latt...

Abstract

This invention relates to an analysis method for an expression including: A, replacing the operation numbers appeared in said expression to the names of said operation numbers orderly and the names are corresponding to the operation numbers, B, testing the expression in step A legally and converting from the front expression to the back, C, replacing the names contained in the back expression to original operation number orderly, D, when a network system gives a data report, it computes the expression replaced by step C.

Description

technical field [0001] The invention relates to an analysis method for expressions in a computer system, in particular to an analysis method for complex expressions. Background technique [0002] The threshold management system is the core sub-module of the performance management subsystem in the network management system (NMS, network management system for short). Usually, the threshold management system analyzes and calculates the expression for alarm judgment input by the user according to the monitoring data reported by the network management system, and then judges whether the alarm system needs to be turned on or off according to the calculation result, In this way, the performance management in the network management system is realized. It can be seen from the above threshold management process that the analysis method of the expression input by the user is one of the key technologies for performance management of the network management system. [0003] The method f...
