ps_system_cpu_times()

Details

Platform-specific fields:

• nice (UNIX): time spent by niced (prioritized) processes executing in user mode; on Linux this also includes guest_nice time.

• iowait (Linux): time spent waiting for I/O to complete. This is not accounted in idle time counter.

• irq (Linux): time spent for servicing hardware interrupts.

• softirq (Linux): time spent for servicing software interrupts.

• steal (Linux 2.6.11+): time spent by other operating systems running in a virtualized environment.

• guest (Linux 2.6.24+): time spent running a virtual CPU for guest operating systems under the control of the Linux kernel.

• guest_nice (Linux 3.2.0+): time spent running a niced guest (virtual CPU for guest operating systems under the control of the Linux kernel).
