The present invention discloses an application process monitoring method, device, medium and
computer program product, which relate to the field of
computer technology. When monitoring that the memory occupancy status of a target device meets the triggering condition of a memory exhaustion terminator, the weight
score of the application process is determined according to the
business logic weight of the application process and the priority weight of the application process, and the memory exhaustion
score of the application process is determined according to the
process memory occupancy parameter of the application process and the weight
score of the application process to determine the target process, and a memory
recovery operation is performed on the target process. The
process selection method of the memory exhaustion terminator mechanism is optimized to make it meet the
business logic requirements, thereby reducing the situation where key processes of business applications are
shut down when the
system memory is recovered, ensuring the normal operation of the
system, and improving the user experience.
