LINUX log controller and method

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
