Abstract
A method and system is provided for detecting excessive interrupt processing for a processor. The method includes the operation of defining an interrupt processing period during which measuring of interrupts for a processor takes place. The amounts of time being spent by the processor in an interrupt context can then be measured during the interrupt processing period. A further operation is detecting an interrupt storm occurring for the processor based on the amounts of time spent by the processor in interrupt context during the interrupt processing period.
