CPU

The CPU section provides information about CPU usage and performance statistics, which illustrate Multi-Port Monitor performance and load.

CPU

Identifies the CPU on the appliance to which the statistics correspond. One of the following values:

All: Statistics that are averaged for all processors.
0 through 15: The CPU identifier, 0 through 15. The Multi-Port Monitor platform has a dual quad core CPU with hyper-threading that appears as 16 CPUs.

User

The percentage of CPU time of processes executing at the user level.

Nice

The percentage of CPU time of processes executing at the user level with nice priority. The kernel determines priority.

System

The percentage of CPU usage attributable to the kernel itself.

IO Wait

The percentage of time that the CPU was idle, but the system had an outstanding disk I/O request.

IRQ

The percentage of CPU time spent processing interrupt requests.

Soft

The percentage of CPU time spent in soft interrupt state.

Steal

The percentage of CPU time that a virtual CPU is waiting for a real CPU while the hypervisor services another virtual processor.

Idle

The percentage of time that the CPU was idle, and the system did not have an outstanding disk I/O request.

Interrupts/Sec

The total number of interrupts that the CPU received per second.
