Diagnostic system in use for Java application

Abstract

The present invention aims to provide a light-weight diagnostic system for Java applications, which allows switching collection and diagnostic options during operation to save performance overhead. The diagnostic system includes a machine (1000) running a Java application and a machine (2000) connected to the machine (1000) through a communication protocol. The machine (1000) is equipped with a Java virtual machine (1010) and a diagnosis machine (1010) as a diagnostic device. The analysis agent unit (1020), in the above-mentioned machine (2000), is provided with a diagnosis client (2010), characterized in that the above-mentioned diagnosis analysis agent unit (1020) has: for opening or closing a prescribed diagnosis function during operation A switch controller (1021); a filter controller (1022) for filtering information requiring diagnosis; and a timing controller (1023) for starting the diagnosis function at a specified time.

Description

technical field [0001] The invention relates to a system of software development tools, in particular to a diagnostic system for Java applications. Background technique [0002] At present, with the development of software technology, the problems that software can handle are becoming more and more complex, and the scale of software is also increasing. Almost all software systems inevitably have problems such as program errors and performance bottlenecks. In recent years, people try to avoid or discover these problems as early as possible from various aspects, so as to reduce the maintenance cost after the system goes online. These measures include: [0003] Use high-level programming languages ​​(such as Java, because the memory problem is well solved, the chance of memory leaks is greatly reduced); [0004] Design patterns and software reuse (design patterns are a summary of the experience of common problems, and like software reuse, they help to avoid repetition of sim...

AI Technical Summary

Problems solved by technology

[0009] First, PA is injected into the application JVM through the Java command line, which means that the system must be restarted to load PA;

[0010] Second, the PA function cannot be cut, which may greatly affect the application performance, which means that it cannot be deployed on the production system;

[0011] Third, the client analysis function cannot be expanded unless the tool is upgraded
