The processor then interrupts its current activities and executes the interrupt handler -to deal with the event. This is part of the way a computer multitasks and handles concurrent processing. - -The types of interrupts include: - -- **I/O interrupts**: These are caused by I/O devices like the keyboard, mouse, printer, etc. For example, when - you type something on the keyboard, an interrupt is triggered so the processor can handle the new input. - -- **Timer interrupts**: These are generated at regular intervals by the system's timer circuit. It's primarily - used to switch the CPU among different tasks. - -- **Software interrupts**: These are generated by a program requiring disk I/O operations, or other system resources. - -- **Hardware interrupts**: These are caused by hardware conditions such as power failure, overheating, etc. - -Monitoring `/proc/interrupts` can be used for: - -- **Performance tuning**: If an interrupt is happening very frequently, it could be a sign that a device is not - configured correctly, or there is a software bug causing unnecessary interrupts. This could lead to system - performance degradation. - -- **System troubleshooting**: If you're seeing a lot of unexpected interrupts, it could be a sign of a hardware problem. - -- **Understanding system behavior**: More generally, keeping an eye on what interrupts are occurring can help you - understand what your system is doing. It can provide insights into the system's interaction with hardware, - drivers, and other parts of the kernel. - - - - -This collector is supported on all platforms. - -This collector supports collecting metrics from multiple instances of this integration, including remote instances. - - -### Default Behavior - -#### Auto-Detection - -This integration doesn't support auto-detection. - -#### Limits - -The default configuration for this integration does not impose any limits on data collection. - -#### Performance Impact - -The default configuration for this integration is not expected to impose a significant performance impact on the system. - - -## Metrics - -Metrics grouped by *scope*. - -The scope defines the instance that the metric belongs to.
