Tracking method, apparatus, device, and machine-readable medium
A tracking method, an apparatus, a device, and a machine-readable medium are provided. The method specifically includes: writing a tracking result of an activity of an operating system and/or a running activity of a program into a buffer when an interrupt is disabled; and reading and sending the tracking result from the buffer when the interrupt is enabled. The embodiments of the present disclosure can effectively shorten the maximum time during which interrupts are disabled for an operating system, and thereby can effectively improve the performance of the operating system and/or a program.

enabling the interrupt after the tracking result is written into the buffer;
reading the tracking result from the buffer and sending the tracking result to a device via a communication interface according to a preset period in response to determining that the interrupt is enabled; and
entering a sleep state according to the preset period after sending the tracking result.
2. The method of claim 1 , wherein: prior to writing the tracking result of the activity of the operating system or the running activity of the program into the buffer in response to determining that the interrupt is disabled, the method further comprises disabling the interrupt in response to detecting that an API of the operating system or the program is called, and corresponding calling information satisfies a preset condition.
