-A This option is equivalent to specifying -n -u -I ALL.
This option also implies specifying -N ALL -P ALL unless
these options are explicitly set on the command line.
--dec={ 0 | 1 | 2 }
Specify the number of decimal places to use (0 to 2,
default value is 2).
-I { keyword[,...] | ALL }
Report interrupts statistics. Possible keywords are CPU,
SCPU, and SUM.
With the CPU keyword, the number of each individual
interrupt received per second by the CPU or CPUs is
displayed. Interrupts are those listed in /proc/interrupts
file.
With the SCPU keyword, the number of each individual
software interrupt received per second by the CPU or CPUs
is displayed. This option works only with kernels 2.6.31
and later. Software interrupts are those listed in
/proc/softirqs file.
With the SUM keyword, the mpstat command reports the total
number of interrupts per processor. The following values
are displayed:
CPU Processor number. The keyword all indicates that
statistics are calculated as averages among all
processors.
intr/s Show the total number of interrupts received per
second by the CPU or CPUs.
The ALL keyword is equivalent to specifying all the
keywords above and therefore all the interrupts statistics
are displayed.
-N { node_list | ALL }
Indicate the NUMA nodes for which statistics are to be
reported. node_list is a list of comma-separated values
or range of values (e.g., 0,2,4-7,12-). Note that node all
is the global average among all nodes. The ALL keyword
indicates that statistics are to be reported for all
nodes.
-n Report summary CPU statistics based on NUMA node
placement. The following values are displayed:
NODE Logical NUMA node number. The keyword all indicates
that statistics are calculated as averages among
all nodes.
All the other fields are the same as those displayed with
option -u (see below).
-o JSON
Display the statistics in JSON (Javascript Object
Notation) format. JSON output field order is undefined,
and new fields may be added in the future.
-P { cpu_list | ALL }
Indicate the processors for which statistics are to be
reported. cpu_list is a list of comma-separated values or
range of values (e.g., 0,2,4-7,12-). Note that processor
0 is the first processor, and processor all is the global
average among all processors. The ALL keyword indicates
that statistics are to be reported for all processors.
Offline processors are not displayed.
-T Display topology elements in the CPU report (see option -u
below). The following elements are displayed:
CORE Logical core number.
SOCK Logical socket number.
NODE Logical NUMA node number.
-u Report CPU utilization. The following values are
displayed:
CPU Processor number. The keyword all indicates that
statistics are calculated as averages among all
processors.
%usr Show the percentage of CPU utilization that
occurred while executing at the user level
(application).
%nice Show the percentage of CPU utilization that
occurred while executing at the user level with
nice priority.
%sys Show the percentage of CPU utilization that
occurred while executing at the system level
(kernel). Note that this does not include time
spent servicing hardware and software interrupts.
%iowait
Show the percentage of time that the CPU or CPUs
were idle during which the system had an
outstanding disk I/O request.
%irq Show the percentage of time spent by the CPU or
CPUs to service hardware interrupts.
%soft Show the percentage of time spent by the CPU or
CPUs to service software interrupts.
%steal Show the percentage of time spent in involuntary
wait by the virtual CPU or CPUs while the
hypervisor was servicing another virtual processor.
%guest Show the percentage of time spent by the CPU or
CPUs to run a virtual processor.
%gnice Show the percentage of time spent by the CPU or
CPUs to run a niced guest.
%idle Show the percentage of time that the CPU or CPUs
were idle and the system did not have an
outstanding disk I/O request.
-V Print version number then exit.
