Performance data

intr/s intr_cpu0/s intr_cpu1/s ...

Usage note

The variable intr report the total number of interrupts, for each of the possible system interrupts, including unnumbered architecture specific ones.

The performance data intr_cpuN report the number of interrupts per cpu per IO device.

Since Linux 2.6.24, for the i386 and x86_64 architectures at least, this also includes interrupts internal to the system (that is, not associated with a device as such.)
