1. Field of the Invention
The present invention relates a method for outputting a system log under an operating system, and more particularly to a system and a method for filtering a system log under an operating system.
2. Description of the Related Art
Technological products are developed quickly. Besides personal computers and notebook computers, electronic devices, such as smart phones or tablet computers, are widely applied in daily use. Since these electronic devices are hardware, the electronic devices need to be installed with software to meet needs of users. For example, the electronic device is installed with an operating system (OS). The operating system is a program between the hardware and the software, and the operating system may allocate system resources, provide environment to execute the software, and provide a user interface. For example, the operating system may be Windows™, Mac™ OS, Linux™, or Unix-Like.
The operating system has a procedure to record multiple system logs, such as logfiles of the operating system. For example, the procedure may be Syslog. The Syslog may transmit the system logs in an internet protocol, and a user may analyze the operating system according to the system logs. Then, the user may realize that when, where, how, and what acts of a file is executed. In other words, the system logs may record information when the operating system works, and such information may include what procedure operates the operating system and what event happens. A program designer may acquire the system logs to analyze, further troubleshoot the operating system and Internet service, and record login information.
The Syslog records the system logs according to a “message level” set by the program designer, but the system logs corresponding to the message level are disorganized. Then, the program designer may inconveniently analyze and debug the system logs. Further, the system logs are too many to recognize useful information, and debugging difficulties are increased. When a processor of the electronic device is overloaded, the processer may not efficiently execute the Syslog, and the system logs may not be immediately recorded. Then, the program designer may not immediately find out the problems of the operating system. Therefore, the technique of recording a system log needs to be improved.
An objective of the present invention is to provide a system and a method for filtering a system log under an operating system. A program designer may set conditions to filter out a specific system log when program runtime stage of the operating system is executed, and may change the conditions to filter out another system log when program runtime stage is executed. Then, the program designer may efficiently analyze the operating system according to the filtered system log.
To achieve the foregoing objective, the method for filtering a system log under an operating system is implemented on an electronic device installed with the operating system, and the electronic device executes a system log filter procedure. The method comprises the steps of:
executing a program compile-time stage to establish an editable database; wherein the editable database stores debugging information;
executing a program runtime stage, receiving configured filtered information, and executing a system record procedure of the operating system to output a filtered system log according to the debugging information stored in the editable database and corresponding to the configured filtered information.
The electronic device is installed with the operating system, and may be used by a user. The electronic device may execute the system log filter procedure, and the system log filter procedure may execute the program compile-time stage and the program runtime stage. Further, the system log filter procedure may receive the configured filtered information, and then may output the filtered system log recorded by the system record procedure of the operating system. Therefore, efficiency of tracing a specific system log may be raised.
Besides, to achieve the foregoing objective, the system for filtering the system log under the operating system comprises an electronic device installed with the operating system, and the electronic device comprises:
an input unit, configured to receive information inputted by a user;
an output unit;
a transmitting unit, configured to receive information inputted by a remote user;
a memory unit; and
a central processing unit, configured to be electronically connected to the input unit, the output unit, the transmitting unit, and the memory unit;
wherein the central processing unit executes a system log filter procedure according to command information input by the user;
wherein the system log filter procedure comprises a program compile-time stage and a program runtime stage;
wherein the system log filter procedure executes the program compile-time stage to store debugging information edited by the user in the memory unit;
wherein when the system log filter procedure executes the program runtime stage, the system log filter procedure receives configured filtered information;
wherein the central processing unit executes a system record procedure to output a filtered system log of the operating system according to the debugging information stored in the memory unit and corresponding to the configured filtered information, and the output unit outputs the filtered system log.
The electronic device receives information input by the user using the input unit, or receives remote information input by the user using the transmitting unit. The central processing unit executes the system log filter procedure according to the command information input by the user. The system log filter procedure executes the program compile-time stage to store debugging information edited by the user in the memory unit. When the system log filter procedure executes the program runtime stage, the system log filter procedure receives the configured filtered information. Then, the central processing unit executes the system record procedure to output a filtered system log of the operating system according to the debugging information stored in the memory unit and corresponding to the configured filtered information, and the output unit outputs the filtered system log.
Further, the central processing unit receives new configured filtered information remotely configured by the user through the transmitting unit. Then, the central processing unit outputs another filtered system log of the operating system according to the debugging information stored in the memory unit and corresponding to the new configured filtered information. Therefore, the user may recognize and analyze the filtered system log, and the efficiency of tracing a specific system log may be raised.
