Problems solved by technology

In the process of R&D, maintenance and use of embedded systems, even if the log output environment is different, it can only rely on a single log output mode, instead of flexibly switching and configuring various log output modes according to the environment, such as serial port output mode, File output mode, network output mode, etc.
[0003] In summary, the existing LINUX log management technology in embedded systems obviously has inconvenience and defects in actual use, so it is necessary to improve

Abstract

The invention discloses a management device of a LINUX log, which is used in an embedded system comprising an application layer and a kernel. The management device comprises: an application layer log used for outputting user mode log information through an output function of the application layer log; a log transmission device for the application layer kernel used for transferring the user mode log information to the kernel; a kernel log used for outputting kernel mode log information through the output function of the kernel log; and a log output controlling device used for receiving the user mode log information that is output by the log transmission device for the application layer kernel and the kernel mode log information that is output by the kernel log respectively, and deploying, processing and outputting the log information. The invention also correspondingly discloses a management method of the LINUX log. In this way, the invention limberly deploys and switches various log output modes according to environments, and provides convenience to the research and development, the maintenance and the use of the embedded system.

Description

technical field [0001] The invention relates to the field of embedded system development and diagnosis, in particular to a management device and method for LINUX logs. Background technique [0002] With the development of science and technology, embedded systems are widely used in various fields of society, such as education, entertainment, national defense, etc. Embedded development has become an important direction of modern computer software industry. Because the hardware resources of the embedded system are very streamlined, the log output of the embedded system cannot be the same as that of a mainframe computer. There are massive storage media, and key information can only be stored in storage units such as FLASH (flash memory) with limited capacity in the embedded system. superior. When developers and maintenance personnel need to view logs, they need to install additional special devices, such as serial port devices, log servers, etc. At the same time, LINUX systems...
