Problems solved by technology

[0004] 1. The monitored information is very complex, and many types of information are not closely related to the actual operating environment. Therefore, the degree of customization is very low and cannot be closely integrated with the actual operating environment.
[0005] 2. Mainly analyze whether the Java virtual machine process is alive or not, and it is difficult to analyze deep information such as the survival of objects inside the Java virtual machin

Abstract

The invention discloses a Java virtual machine internal object monitoring method, device and system. The Java virtual machine internal object monitoring method comprises the steps that a class loading tree of a Java virtual machine process to be monitored is obtained according to a process ID distributed by an operating system, and the class loading tree is converted into a class assembly list; class information in the class assembly list is filtered according to filtering conditions and class object information is obtained from the filtered class information, key data of a class object are analyzed according to the class object information, and meanwhile, the key data are stored in a cache and a database; the key data obtained through monitoring in a preset time period are collected, and a collection report is generated; the data in the collection report are displayed on a page in multiple modes. The Java virtual machine internal object monitoring method can be well combined with a practical operation environment, and can provide vivid and clear prompts for system operation maintenance staff.

Description

technical field [0001] The invention relates to the technical field of computer application software, in particular to the technical field of Java virtual machines, and in particular to a method, device and system for monitoring internal objects of a Java virtual machine. Background technique [0002] Java Virtual Machine (Java Virtual Machine, referred to as JVM) is a fictitious computer, which is realized by simulating various computer functions on an actual computer. The Java virtual machine includes a set of bytecode instructions, a set of registers, a stack, a garbage collection heap, and a storage method field. The Java virtual machine shields the information related to the operating system platform, so that the Java program can run without modification on various platforms only by generating the object code (byte code) that runs on the Java virtual machine. [0003] When running a Java program through a Java virtual machine, because the class information of the Java ...
