Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] The basic design idea of ​​the technical solution of the present invention is: send the http request of modifying log level of log4j through web browser, call log4j interface according to this http request, dynamically revise the log level of log4j, make log4j output relevant log according to the log level after modification , so that maintenance personnel can check the information of this log level in time, and can locate system problems without restarting java services or processes.

[0040] In order to illustrate the technical solutions of the various embodiments of the present invention more clearly, the technical terms involved in dynamically modifying the log level of log4j based on the http request are introduced.

Abstract

The invention discloses a method and a device for modifying the log level. The method includes: receiving an http request sent by a web browser to modify the log level of the java log framework log4j, wherein the http request includes parameter information after log level modification; parsing out the log level modification from the http request After the parameter information; call the log4j interface, the log level of the log4j is dynamically modified according to the modified parameter information of the log level; output the log4j log according to the modified log level. The technical scheme of the present invention can dynamically modify the log level of log4j by sending an http request, without restarting the java application system or service, so that the maintenance personnel can immediately check the information of the log level, which is convenient for locating system problems; after the maintenance personnel find the problem, they can Change the log level to advanced in time to reduce the amount of log output, reduce resource consumption, and shorten the time cost of operation and maintenance.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for modifying log levels. Background technique [0002] In today's emphasis on the development of reusable components, in addition to developing a reusable log operation class from beginning to end, Apache provides us with a powerful java log framework Log4j. [0003] Log4j is a Java-based open source log component. Log4j is very powerful. We can output log information to the console, file, user interface, or to the event recorder of the operating system and some system resident processes. Through Log4j, it is very convenient to customize the log format and log level, which can help developers to control the log information in all directions. Generally, when a problem occurs in a Java system and the system log needs to be searched, the operation and maintenance personnel usually adjust the log4j log level to debug to obtain more log information.
