I have the feeling that rate is calculated like this:
number of interrupts since boottime / seconds of uptime
so, this won't help if his is having now an interrupt storm
while most of the time the system is interrupted ~ 120 times
per second
systat -vmstat $time shows interrupts per second regarding the last $time
seconds
