JAVA virtual machine memory leak detection method and device

Abstract

The embodiment of the invention provides a JAVA virtual machine memory leak detection method and device, and the method comprises the steps: obtaining the memory block information of a JAVA virtual machine after each garbage collection GC in a first preset time period at intervals of the first preset time period; judging whether the memory block information of the JAVA virtual machine after garbage collection GC each time in the first preset time period conforms to a preset memory leakage rule or not; and if the memory block information of the JAVA virtual machine after all garbage collectionGC in the first preset time period conforms to a preset memory leakage rule, determining that memory leakage occurs in the JAVA virtual machine. According to the embodiment of the invention, the memory leakage condition of the JAVA virtual machine can be discovered in advance to give an alarm and solve the problem in advance, so that the downtime probability of the application is greatly reduced,and the detection accuracy is high.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for detecting memory leaks of a JAVA virtual machine. Background technique [0002] With the increasing demand for computer applications, the design and development of application programs have also become increasingly complex, and the number of variables that developers deal with in the process of program implementation has also increased significantly. How to effectively allocate and release memory and prevent memory leaks becomes a problem. become more and more prominent. For example, the server application software needs to run for a long time and continuously process the requests sent by the client. If there is no effective memory management, there will be a certain memory leak every time the request information is processed. This not only affects the performance of the server, but may also cause the entire system to crash. During the operation of JVM...

[0004] However, the current method of using third-party tools to obtain memory usage based on the heap dump file, judging the points where memory leaks may occur based on the experience of operation and maintenance personnel, and combining the code to check whether memory leaks occur requires manual analysis. The experience and ability of operation and maintenance personnel are high, and the detection efficiency is low; due to the randomness of memory leaks, this method is not easy to find the crux of the problem, and the application is in an unavailable state when using this method
