slot slot-number
: Specifies an IRF member device by its member ID. If you specify a process
but do not specify a member device, this command displays the statistics for the process on the
master device. If you do not specify any options, this command displays the statistics for all
processes on all member devices.
cpu cpu-number
: Specifies a CPU by its number. If you specify a process but do not specify a
CPU, this command displays the statistics for the default CPU. If you do not specify a process or
CPU, this command displays the historical statistics for all CPUs.
Usage guidelines
After CPU usage monitoring is enabled, the system regularly samples CPU usage and saves the
samples to the history record buffer. This command displays the most recent 60 samples in a
coordinate system as follows:
The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is
rounded up or down to the closest multiple of the usage step. For example, if the CPU usage step is
5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded down to 50%.
The horizontal axis represents the time.
Pound signs (#) indicate the CPU usage. The value on the vertical axis for the topmost pound sign at
a specific time represents the CPU usage at that time.

cpu-usage (Slot 1 CPU 0) last 60 minutes (SYSTEM)
The output shows the following items:
•
Process name. The name SYSTEM represents the entire system.
•
CPU that is holding the process: CPU 0 in slot 1.
•
Historical CPU usage statistics for the entire system during the last 60 minutes.
