This application provides a process monitoring method, electronic device, storage medium, and computer program product. The method includes: acquiring file access events of a target directory; responding to the file access events, reading a process file system to obtain first runtime information of multiple Linux processes, wherein the process file system is used to provide runtime information of all Linux processes under non-privileged user privileges, and the non-privileged user privileges do not have control permissions in the Linux kernel mode; and generating a process activity log based on the first runtime information of the multiple Linux processes. This application's solution allows for more comprehensive monitoring of process activities in a Linux system.

The invention provides an interrupt monitoring method and device for an operating system kernel in a multi-kernel processing system, and the method comprises the steps: collecting interrupt event data of a corresponding CPU core through a monitoring unit; executing interrupt storm detection and interrupt processing delay monitoring based on the collected interrupt event data; when an interrupt storm event is detected or an interrupt processing delay abnormity is monitored, generating diagnosis information which comprises at least one of an interrupt number, a device identifier, a call stack and a process context; and outputting a monitoring result and diagnosis information through a configuration interface and a query interface provided by the ProcFs file system. According to the method, through a distributed low-overhead architecture and an intelligent triggering mechanism, real-time, accurate, operable and maintainable production-level monitoring of interruption storm and processing time delay of the multi-core system is realized.
