CPU stats description:
* user: percent time spent in user space
> User CPU time is time spent on the processor running your program's code (or code in libraries)
* system: percent time spent in kernel space
> System CPU time is the time spent running code in the operating system kernel
* idle: percent of CPU used by any program
> Every program or task that runs on a computer system occupies a certain amount of processing time on the CPU. If the CPU has completed all tasks it is idle.
* nice: percent time occupied by user level processes with a positive nice value
> The time the CPU has spent running users' processes that have been "niced"
* irq: percent time spent servicing/handling hardware/software interrupts
> Time servicing interrupts (hardware + software)
* iowait: percent time spent in wait (on disk)
> Time spent by the CPU waiting for a IO operations to complete
* steal: percent time in involuntary wait by virtual CPU
> Steal time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor
* ctx_sw: number of context switches (voluntary + involuntary) per second
> A context switch is a procedure that a computer's CPU (central processing unit) follows to change from one task (or process) to another while ensuring that the tasks do not conflict
* inter: number of interrupts per second
* sw_inter: number of software interrupts per second. Always set to 0 on Windows and SunOS.
* syscal: number of system calls per second. Do not displayed on Linux (always 0).
- **user**: percent time spent in user space. User CPU time is the time
spent on the processor running your program's code (or code in
libraries).
- **system**: percent time spent in kernel space. System CPU time is the
time spent running code in the Operating System kernel.
- **idle**: percent of CPU used by any program. Every program or task
that runs on a computer system occupies a certain amount of processing
time on the CPU. If the CPU has completed all tasks it is idle.
- **nice** *(\*nix)*: percent time occupied by user level processes with
a positive nice value. The time the CPU has spent running users'
processes that have been *niced*.
- **irq** *(Linux, \*BSD)*: percent time spent servicing/handling
hardware/software interrupts. Time servicing interrupts (hardware +
software).
- **iowait** *(Linux)*: percent time spent by the CPU waiting for I/O
operations to complete.
- **steal** *(Linux)*: percentage of time a virtual CPU waits for a real
CPU while the hypervisor is servicing another virtual processor.
- **ctx_sw**: number of context switches (voluntary + involuntary) per
second. A context switch is a procedure that a computer's CPU (central
processing unit) follows to change from one task (or process) to
another while ensuring that the tasks do not conflict.
- **inter**: number of interrupts per second.
- **sw_inter**: number of software interrupts per second. Always set to
0 on Windows and SunOS.
- **syscal**: number of system calls per second. Do not displayed on
Linux (always 0).
