System and method for remotely obtaining real-time graded debugging information of kernel module

Abstract

The invention discloses a system and a method for remotely obtaining the real-time graded debugging information of a kernel module, and the system and the method relate to the field of computer systems. The system comprises target equipment and monitoring equipment; the target equipment carries out communication with the monitoring equipment through an IP (Internal protocol) network; the target equipment comprises the kernel module and a debugging module; the monitoring equipment comprises a remote monitoring module; the kernel module generates and sends debugging information to the debugging module; the remote monitoring module sends a connection command to the debugging module to record; when a debugging grade is set or changed, the remote monitoring module sends a setting command to the debugging module; the debugging module stores the debugging grade in the debugging module after receiving the setting command and sends the debugging information according with a filtration condition to the remote monitoring module; and the remote monitoring module stores and displays the received debugging information and sends a closing command to the debugging module when the debugging is completed. By using the system and the method, a debugger and a maintainer can remotely carry out trace debugging and are not necessary to rush towards a field; lots of labor power and material resources can be saved; and the timeliness for the fault diagnosis of the kernel module is met.

Description

technical field [0001] The invention relates to the field of computer system debugging and fault diagnosis, in particular to a system and method for remotely acquiring real-time hierarchical debugging information of a kernel module. Background technique [0002] In modern industrial equipment, as small as mobile phones and electronic dictionaries; as large as airplanes and rockets, the core control units inside are computer systems, and some computer systems even use multiple embedded computer systems. In the above computer system, the kernel module is the most critical module. The failure of the kernel module will lead to unstable operation of the computer system, and in severe cases, the computer system will crash and cause serious economic losses. Therefore, it is necessary to obtain accurate debugging information and solve problems as quickly as possible. [0003] In the process of development, debugging and fault diagnosis of the computer system kernel module, the exis...

Problems solved by technology

[0006] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide a system and method for remotely obtaining the real-time hierarchical debugging information of the kernel module, and remotely obtain the debugging information of the kernel module through the IP network, which can effectively solve the problem that the real-time debugging information of the kernel module cannot be obtained remotely. The problem of debugging information enables debuggers and maintenance personnel to track and debug remotely without having to rush to the site, which can save a lot of manpower and material resources; at the same time, they can obtain fault information in a timely and accurate manner to meet the timeliness of kernel module fault diagnosis
