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

The embodiment of the invention provides an overtime detection method and device, equipment and a storage medium, and the method comprises the steps: adding a first timestamp to a process when the process is monitored to be switched from a user mode to a kernel mode; determining the running duration of the process in the kernel mode according to the first timestamp and the current moment; when therunning duration exceeds a threshold value, determining that the running of the process in the kernel mode is overtime; and when the total running duration corresponding to the process running completion moment does not exceed the threshold value, determining that the running of the process in the kernel mode is not overtime. Through the method and the device, the running time overrun of the process in the kernel mode can be detected in time, and the analysis and positioning efficiency of the timeout problem and the maintainability of the system are improved.

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...
