Problems solved by technology

[0004] PHP (Hypertext Preprocessor, Hypertext Preprocessor) script is a process executed by a PHP interpreter, but the existing strace and pstack can only provide the system call information of the PHP interpreter, but cannot provide the information of the PHP script. Therefore, Unable to meet the analysis needs of PHP scripts

Abstract

The embodiment of the present invention provides a method and device for process cleaning, creating a PHP tracking program in the PHP interpreter; using the PHP tracking program to track the function information in the execution process of the operation compiled by the PHP interpreter for the process ; According to the function information, detect whether the usage rate of the processor corresponding to the PHP interpreter is greater than a preset threshold; when it is detected that the processor usage rate is greater than the preset threshold, from the running process Select non-essential processes in and clear the non-essential processes. The embodiment of the present invention can acquire and output function information in the execution process of an operation in real time, so that developers of PHP scripts can quickly locate PHP script problems.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a process cleaning method and device. Background technique [0002] There are usually multiple processes running in operating systems such as Linux and Unix. At present, when the process has problems such as long running time and running errors, it is necessary to analyze the cause of the problem by monitoring the process. [0003] Existing solutions can combine strace and pstack tools to directly find function calls that affect the running time of a process, and then perform code analysis and optimization on related functions in a targeted manner. Among them, the strace tool can track the underlying system calls used by the process, and can output the time point when the system call is executed and the time-consuming of each call; the pstack tool can output the function call stack for the process of the specified PID (Process ID, Process Identity). [0004] PHP (Hypertext Pr...
