Problems solved by technology

[0003] Usually the operating system kernel may stay in the kernel state for a long time due to various reasons, resulting in the failure of other application processes to be scheduled, resulting in exceptions or alarms for delay-sensitive services
[0004] However, in related technologies, only when the process is in the user state, will the process timeout be detected. When the process is switched from the user state to the kernel state, there is no relevant timeout detection means in the related technology.

Abstract

An embodiment of the present application provides a timeout detection method, device, device, and storage medium, wherein the method includes: adding a first timestamp to the process when it is detected that the process is switched from the user state to the kernel state; according to the The first time stamp and the current moment determine the running time of the process in the kernel state; when the running time exceeds a threshold, determine that the process runs overtime in the kernel state; when running with the process When the total running time corresponding to the completion time does not exceed the threshold, it is determined that the running of the process in the kernel mode has not timed out. Through this application, it is possible to timely detect that the running time of the process in the kernel state exceeds the limit, and improve the analysis and positioning efficiency of the timeout problem and the maintainability of the system.

Description

technical field [0001] The embodiments of the present application relate to the field of computers, and relate to, but are not limited to, a timeout detection method, device, device, and storage medium. Background technique [0002] The business applications running on the server are basically background server applications. These applications need to process a large number of service requests and provide high-performance services. However, there are also some applications that not only require high performance, but also have relatively high requirements for real-time performance and are sensitive to system delays. For such applications, the current general-purpose operating systems provide some patches and features to meet the special needs of these applications, so that such applications can run normally and stably. [0003] Usually the operating system kernel may stay in the kernel state for a long time due to various reasons, resulting in the failure of other applicatio...
