Watchdog monitoring method, system and device and storage medium

Abstract

The invention discloses a watchdog monitoring method, a watchdog monitoring system, watchdog monitoring equipment and a computer readable storage medium. The method comprises the following steps: monitoring whether an abnormal crash program exists in a target system or not; Wherein the target system comprises a plurality of programs, and each program comprises a plurality of threads and / or a plurality of processes; If yes, obtaining corresponding configuration information according to the identification number of the abnormal crash program; Storing the data of the abnormal crash program according to the configuration information, and judging whether the abnormal crash program needs to be restarted or not according to the configuration information; And if yes, restarting the abnormal crashprogram. According to the watchdog monitoring method provided by the invention, a plurality of programs are managed at the same time, different configuration information is set for each program, onlyan abnormal crash program can be configured to be restarted, the influence on other normal programs and the whole system is reduced, and the resource consumption is reduced. Data needing to be storedwhen a program is hung up can be configured, the site is reserved as much as possible, and troubleshooting and positioning of subsequent problems are facilitated.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a watchdog monitoring method, system and equipment, and a computer-readable storage medium. Background technique [0002] At present, in embedded systems, watchdogs are generally set up. Usually, watchdogs generally only monitor one program, and multiple programs need to use multiple watchdogs, which consume more resources. When the program hangs up, the entire system will be restarted, and some modules without problems will also be restarted at the same time, resulting in a waste of resources. If there is communication with other peripheral devices or the upper computer, it will also cause short-term communication abnormalities. In addition, even if you just restart the program without restarting the system, key information will be lost, which hinders troubleshooting to a certain extent. [0003] Therefore, how to take corresponding measures to reduce waste of r...

Problems solved by technology

[0002] At present, in embedded systems, watchdogs are generally set up. The usual watchdogs generally only monitor one program, and multiple programs need to use multiple watchdogs, which consume more resources.

When the program hangs up, the entire system will be restarted, and some modules without problems will also be restarted at the same time, resulting in a waste of resources

If there is communication with other peripheral devices or the host computer, it will also cause short-term communication abnormalities

In addition, even if you just restart the program without restarting the system, key information will be lost, which will hinder the troubleshooting to a certain extent.
