Monitoring method and device of JAVA application system in running

Abstract

The invention discloses a monitoring method and device of a JAVA application system in running. The JAVA application system monitoring method mainly comprises the steps of: describing a monitored class or method and a monitor control index through a configuration file; (2) modifying starting parameters of an application program, and loading Agent when a JVM (Java Virtual Machine) is started; (3) reading the configuration file by the Agent, and registering an event to be noticed according to a monitoring requirement; (4) obtaining a notice by the Agent when the application program runs and a specified class is loaded; (5) modifying a bytecode of a corresponding class by the Agent, and adding a logic required in monitoring; (6) initializing relevant index variable by the Agent; (7) automatically executing the monitoring logic when the monitored method is called, and obtaining the original data of the relevant index; and (8) computing the value of the relevant index by the Agent according to the description of the configuration file. By applying the JAVA application system monitoring method disclosed by the invention, the ability of an IT (Information Technology) operation and maintenance staff for diagnosing, analyzing, positioning and solving faults of an IT system can be improved remarkably.

Description

technical field [0001] The invention relates to the field of IT operation and maintenance, in particular to a method for monitoring the runtime of a Java application system. Background technique [0002] With the continuous deepening and improvement of IT construction, the operation and maintenance of computer software and hardware systems have become increasingly important. An important aspect to ensure the normal and continuous operation of the application system is to monitor the behavior of the application system, and when it is found that its behavior does not meet expectations or is abnormal, it will be alerted in time, so that maintenance personnel can deal with the problem and eliminate faults or potential problems. Rapid changes in business and continuous innovation in technology lead to increasingly complex application systems. There may be dozens or even hundreds of business systems in large enterprises. When a fault occurs, problem location, diagnosis, and repair...

AI Technical Summary

Problems solved by technology

In monitoring technology, various probes are generally used to observe the CPU and memory resources occupied by the application system from the outside, which cannot monitor the internal behavior and effect of the application system, and cannot locate and analyze deep-seated system problems.

The traditional software single-step tracking and debugging technology can accurately observe the internal behavior of the system, which is mainly applicable to the software development stage. After the system is put into formal operation, it is difficult to perform single-step tracking and debugging on the system due to the lack of source code and symbol files. ; and single-step tracking, breakpoints, etc. will affect the behavior of the application system, and are generally not allowed to be used in a production environment
