System CPU times.

Source: R/system.R
ps_system_cpu_times.Rd

Every attribute represents the seconds the CPU has spent in the given mode. The attributes availability varies depending on the platform:

  • user: time spent by normal processes executing in user mode; on Linux this also includes guest time.

  • system: time spent by processes executing in kernel mode.

  • idle: time spent doing nothing.

Usage

ps_system_cpu_times()

Value

Named list

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).
