MPSTAT(1) Linux User's Manual MPSTAT(1)
NAME
mpstat - Report processors related statistics.
SYNOPSIS
mpstat [ -P { cpu | ALL } ] [ -V ] [ interval [ count ] ]
DESCRIPTION
The mpstat command writes to standard output activities for each available processor, processor 0 being the first one. Global average
activities among all processors are also reported. The mpstat command can be used both on SMP and UP machines, but in the latter, only
global average activities will be printed.
The interval parameter specifies the amount of time in seconds between each report. A value of 0 indicates that processors statistics are
to be reported for the time since system startup (boot). The count parameter can be specified in conjunction with the interval parameter
if this one is not set to zero. The value of count determines the number of reports generated at interval seconds apart. If the interval
parameter is specified without the count parameter, the mpstat command generates reports continuously.
REPORTS
The report generated by the mpstat command has the following format:
CPU
Processor number. The keyword all indicates that statistics are calculated as averages among all processors.
%user
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.
%system
Show the percentage of CPU utilization that occurred while executing at the system level (kernel).
%idle
Show the percentage of time that the CPU or CPUs were idle.
intr/s
Show the total number of interrupts received per second by the CPU or CPUs.
OPTIONS
-P cpu | ALL
Indicate the processor number for which statistics are to be reported. cpu is the processor number. Note that processor 0 is the
first processor. The ALL keyword indicates that statistics are to be reported for all processors.
-V Print version number and usage then exit.
ENVIRONMENT
The mpstat command takes into account the following environment variable:
S_TIME_FORMAT
If this variable exists and its value is ISO then the current locale will be ignored when printing the date in the report header.
The mpstat command will use the ISO format (YYYY-MM-DD) instead.
EXAMPLES
mpstat 2 5
Display five reports of global statistics among all processors at two second intervals.
mpstat -P ALL 2 5
Display five reports of statistics for all processors at two second intervals.
BUGS
/proc filesystem must be mounted for the mpstat command to work.
Only a few activities are supplied by the Linux kernel for each processor.
FILES
/proc contains various files with system statistics.
