    The CPU Usage graph depicts how your machine's CPUs (real or virtual) are used. A single CPU refers to a single (potentially virtualised) hardware hyper-thread in this sense.

      Hey,

      Follow the steps:
      • 1) top Command to View Linux CPU Load. Open a terminal window and enter the following: top.
      • 2) mpstat Command to Display CPU Activity.
      • 3) sar Command to Show CPU Utilization.
      • 4) iostat Command for Average Usage.
      • 5) Nmon Monitoring Tool.
      • 6) Graphical Utility Option.

        CPU utilisation relates to how much a computer's processing capabilities are being used, or how much work it is doing.

          Hey,

          The capacity and type of managed computing jobs influence actual CPU use. Certain jobs necessitate a lot of CPU time, whereas others necessitate a lot less due to non-CPU resource requirements.

            Hey,

            To check CPU utilization follow these steps:
            • A) Start the Task Manager.
            • B) Press the buttons Ctrl, Alt and Delete all at the same time.
            • C) Choose "Start Task Manager." This will open the Task Manager Program window.
            • D) Click the "Performance" tab. On this screen, the first box shows the percentage of CPU usage.

              Hey,

              The user CPU and Nice CPU are both high, indicating that the user-mode process takes up more CPU, thus you should pay attention to the process's performance.

                If the system CPU is high, it means the kernel mode is using a lot of it, so you should pay attention to the performance of kernel threads and system calls.
