inttimes.d - print interrput on-cpu time total. Uses DTrace. inttimes.d This prints the total time each driver instance has spent servicing interrupts. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the sdt provider interrupt probes.

This samples until Ctrl-C is hit. # inttimes.d

DEVICE instance name of the device driver
