How can resource usage of CPU in a system be evaluated?

To assess CPU resource usage in a system, various tools and commands can be used depending on the operating system.

On Linux, common tools include:

• top — an interactive process monitor showing CPU load.
• htop — an improved version of top with a user-friendly interface.
• mpstat — shows CPU usage statistics per core.
• vmstat — provides overall system information, including CPU.

You can also use system utilities or monitoring tools like sar or graphical interfaces.

Example command to view CPU load:

top

This will display the current CPU load in percentage and the processes consuming CPU.
