Overview :: nuug.no :: vert.nuug.no :: irqstats


daily graph weekly graph
monthly graph yearly graph
Shows the number of different IRQs received by the kernel. High disk or network traffic can cause a high number of interrupts (with good hardware and drivers this will be less so). Sudden high interrupt activity with no associated higher system activity is not normal.
