This command is specifically used to get information about how much memory is using each running process. The top command gives you the live view of your total running services on your system.

The top command is pre-installed on most of the latest Linux distributions that give you deep information about CPU utilization of your system. The following commands are used to monitor CPU utilization: $ ls -l -hĬheck CPU and Memory Usage on a Linux system Ls command is so simple and similar to the du command Linux can be used to list all directory contents along with the file size of each. The following command can be used on the terminal to check the total used space: $ du It displays the disk space that is already consumed by files on a disk instead of displaying available space. This command is slightly different from the df command. The ‘du‘ command is also used for Linux disk usage-related purposes. Type the following command on the terminal to check available disk space: $ df When the -h attribute is used with this command, it shows you the file and folders lists through which you can calculate the available disk space. When we use a filename with the ‘df’ command, it shows the free space on the disk partition where that file is saved. The ‘df’ is used to report how much disk space is used in a Linux system. Open the terminal by pressing ‘Ctrl+Alt+t’ and execute one by one the above-mentioned commands on it. The following command-line tools are used to monitor the hard disk usage: So let’s get started! Monitor Hard disk Usage on a Linux system We have tested all the commands in this article on Ubuntu 22.04. In this article, we will learn how to monitor the CPU, RAM, and disk usage of your Linux system. As a Linux system administrator, you are responsible for monitoring the performance of your system. All of these terms can be different from each other.

However, you must decide whether you want to monitor CPU usage, memory usage, or disk usage. You can easily monitor these resources with simple terminal commands.

If you work on Linux servers, you need to check the disk, CPU, and memory usage on your system.
