Abstract

The invention discloses a load-related software aging detection method. The method comprises the following steps: S1, pressurizing to-be-detected software by utilizing a load generator; S2, periodically collecting a plurality of aging variables by utilizing a monitoring tool, simplifying the key variables by adopting a dimension reduction method, performing linear estimation on an aging trend by reducing multicollinearity, analyzing the aging variables, and screening out a monitoring index with the highest correlation; s3, establishing an automatic time sequence analysis model, and analyzing the screened monitoring indexes to obtain a time sequence curve signal; and S4, constructing a deviation graph according to the time sequence curve signal, and judging whether an aging phenomenon exists or not according to a deviation value and a change rule. The software aging detection method solves the problem that a traditional software aging detection method based on trend detection is high infalse alarm rate, facilitates developers to detect the software aging problem in the development stage, and avoids loss caused by the software aging problem.

Description

technical field [0001] The invention belongs to the field of software aging, and in particular relates to a new load-related software aging detection method. Background technique [0002] In long-running operating systems, software aging is the main cause of system performance degradation or software crashes. The complexity and time characteristics of software aging make its detection very difficult. Therefore, detecting software aging in the development and testing phase is one of the important ways to reduce the loss caused by software aging. [0003] Memory leaks are one of the important causes of software aging. Traditional software aging detection methods related to memory leaks mainly use trend analysis to detect software aging by monitoring software resource consumption under stress testing. However, the reason for the increase in resource consumption of software under stress testing may be due to the software's management of resources. Therefore, the traditional me...
