Embodiment Construction
[0028] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0029] A fault-tolerant method for monitoring software in C language under an embedded Linux system. Firstly, an explanation is given to the processing flow of general monitoring software. The monitoring software (main) is a program executed in an infinite loop according to certain timing rules. To ensure the persistent operation of the monitoring software, the monitoring core code (monitor) needs to be stable enough without error. However, as the complexity of the code increases, the probability of errors gradually increases, especially some occasional errors with low recurrence rates. These errors, such as floating-point division by 0, will cause the monitoring program to exit with an error. The code in the table below is the code framework of this embodiment. Take it as an example to describe the fault-tolerant method of the present invention.

The invention provides a C-language monitoring software fault tolerant method based on an embedded Linux system. Since the exception handling structure, similar to the try-catch in the C++ language, is implemented through the C language, faults are captured through the monitoring software at the first time and are handled to prevent program crash, and accordingly, the monitoring software has higher fault tolerance capacity. Besides, when the monitoring software is in segment fault, floating-point calculation fault or exiting fault, execution of the cyclic process of the monitoring program is guaranteed, and fault messages and fault positions can be recorded in fault handling process to facilitate analysis on faults. The invention further provides a system for implementing the operation. As the system is based on the C-language monitoring software fault tolerance strategy and method, the system realizes handling of error programs in the monitoring process, loss of performance is low, operational reliability of the system is improved effectively and hardware customization complexity is reduced.
Description
technical field [0001] The invention belongs to the technical field of server monitoring and management, and in particular relates to a fault-tolerant method for C language monitoring software under an embedded Linux system. Background technique [0002] At present, the embedded Linux system has been widely used in the field of server monitoring. These monitoring software monitor and manage the running status of the server all the time. rerun within the time. [0003] At present, most monitoring software is developed using C language. However, in the C language, there is no exception handling mechanism similar to the trycatch type in C++. Once some problems such as segment faults and floating point operation errors are encountered, the program will crash and exit. To ensure that the program continues to run, the current solution is to regularly check the monitoring software. Once the monitoring software is detected to be abnormally terminated, the monitoring software will ...
