Method, device and storage medium for modifying log level

The invention discloses a method, device and storage medium for modifying a log level, and belongs to the technical field of computers. The method comprises the following steps: a signal processing function is registered in a first application program, when the first application program receives a target signal value sent by a command line tool, the target log level corresponding to the target signal value can be determined directly through the signal processing function, and the current log level can be modified to the target log level. Because the command line tool is a tool on the operatingsystem per se, therefore, by using the method, a user can implement the modification of the log level of the first application program by only using the operating system, which avoids the need of using a web browser to modify the log level of the first application program, and the efficiency of modifying the log level is improved. 本发明公开了种修改日志级别的方法、装置及存储介质，属于计算机技术领域。所述方法包括：在第应用程序中注册信号处理函数，当第应用程序接收到命令行工具发送的目标信号值时，可以直接通过信号处
