procinterrupts

The /proc/interrupts file is a special file in the Linux operating system that displays information about the interrupts that are currently being handled by the system. An interrupt is a signal that is sent to the CPU by a hardware device, such as a keyboard or mouse, to request attention or to notify the system of an event.

The /proc/interrupts file lists the interrupt numbers, the number of times each interrupt has occurred, and the name of the device that generated the interrupt. It also displays the CPU utilization for each interrupt and the total number of interrupts handled by the system.

This file is useful for troubleshooting hardware and software issues, as it can help identify which devices are generating interrupts and how often they are occurring. It can also be used to monitor system performance, as high numbers of interrupts can indicate a bottleneck or performance issue.
