Check CPU utilization in Linux
Understanding CPU processor usage is important for overall system-performance measurement. From Linux enthusiasts to system admins, knowing how to monitor CPU utilization in Linux from the command line is crucial. The system should respond by displaying a list of all the processes that are currently running.
It will also give a readout of users, tasks, CPU load, and memory usage. This list can frequently change, as background tasks start and complete. One helpful switch is to launch top with the —i switch:. To quit the top function, press the letter q on your keyboard. Or, you can enter the following at a command line:.

This command would show you the total, like the basic mpstat command. It will also list processes by individual CPU. To take a series of snapshots, use a number to indicate an interval and a second number to indicate the number of reports:.
The sar tool is a utility for managing system resources. The —u option tells it to display CPU usage. The 5 indicates that it should display every 5 seconds.
This will run indefinitely. To cancel, press Ctrl-C. The system will display average CPU usage since the last boot. More information on iostat can be found on the Linux Manual pages. To install Nmon on Ubuntu, enter the following:. This will launch the utility, and display all the options.
To view CPU usage, press the letter c. To switch back, press c again. For a list of commands, press h. To quit, press q. However, you may have a lightweight GUI, or you may be using a client Linux system. Some versions, like Ubuntu, have a built-in graphical monitoring tool.
