What is idle in Mpstat?
Basics of mpstat % usr : Show the percentage of CPU utilization that occurred while executing at the user level (application). % guest : Show the percentage of time used by the CPU or CPUs to run a virtual processor. % idle : The CPU or CPUs were idle and the system did not have an outstanding disk I / O request.
What is soft in Mpstat?
%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.
What is Mpstat used for?
mpstat is a command that is used to report processor related statistics. It accurately displays the statistics of the CPU usage of the system. It displays information about CPU utilization and performance.
What is Dstat?
dstat is a tool that is used to retrieve information or statistics form components of the system such as network connections, IO devices, or CPU, etc. By using this tool one can even see the throughput for block devices that make up a single filesystem or storage system.
What is the mpstat command in Linux?
Description. The mpstat command collects and displays performance statistics for all logical processors in the system. Users can define both, the number of times the statistics are displayed, and the interval at which the data is updated.

What is Linux Iostat?
The iostat command in Linux is used for monitoring system input/output statistics for devices and partitions. It monitors system input/output by observing the time the devices are active in relation to their average transfer rates.
What does the interval in mpstat stand for?
$ mpstat Interval is the time in seconds between printing out a line of statistics. Count is the number of lines of output you want. Note that the first line of output from mpstat (like iostat, vmstat, etc.) contains averages since system boot.
What does mpstat do on the first processor?
It initializes the first processor with CPU 0, the second one with CPU 1, and so on. 1. To display processor and CPU statistics. This will display all the processor and CPU stats.
How is the Count parameter specified in mpstat?
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.
Which is the default report for mpstat in SMP?
The mpstat command can be used both on SMP and UP machines, but in the latter, only global average activities will be printed. If no activity has been selected, then the default report is the CPU utilization report. The interval parameter specifies the amount of time in seconds between each report.
