Program dynamic monitoring method and device

Abstract

The invention discloses a program dynamic monitoring method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of obtaining a monitoring starting instruction, determining a target monitoring index of a to-be-monitored program according to the monitoring starting instruction, and collecting an index value of the target monitoring index of a process in the to-be-monitored program; storing the index value of the target monitoring index of the process into a memory, and synchronizing the index value to a shared memory; and when an observation instruction is obtained, summarizing and calculating the index values of the target monitoring indexes of the processes in the shared memory, determining final monitoring data of the targetmonitoring indexes, and displaying the final monitoring data. According to the embodiment, the index values of the processes can be collected in real time in the memory and synchronized into the shared memory, and when the observation indexes need to be monitored, summarizing calculation is conducted from the shared memory, so that final monitoring data are obtained. The method for monitoring thedynamic state of the program can be used immediately after opening the box, can be opened and closed, and can also support graphical display.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for monitoring program dynamics. Background technique [0002] With the rapid development of the Internet, the business traffic of network applications is increasing day by day, and there is an increasing demand for high-performance web servers that can handle large concurrency. Due to the increasingly complex business logic, there are more and more demands for expansion on the basis of the server. In recent years, complex business logic is mostly written in scripting languages ​​(such as Lua), which greatly reduces the threshold for high-performance server programming. However, as the business logic written in scripting languages ​​becomes more and more complex, the running monitoring of scripting language programs becomes more and more urgent, and a simple and easy-to-use method is needed to realize real-time dynamic monitoring of online applications. ...

AI Technical Summary

Problems solved by technology

[0005] 1) The threshold for use is very high: the above-mentioned technical solutions require a certain amount of Linux kernel knowledge, which is generally too complicated and has a high learning curve. Users need to master specialized languages ​​such as D language, which increases additional learning costs;

[0006] 2) High risk of use: Since the above technical solutions are based on the linux kernel, and generally require superuser privileges to execute, once there is a problem with the scripting of the probe, it may even affect the system kernel, bringing certain risks to system operation and stability ;

[0007] 3) Poor usability: the above-mentioned technical solutions generally only consider the output of the results, lack of more intuitive and convenient observation methods, for example, generally do not support remote graphical observations, etc.
