How to Check RAM, CPU, and Storage in Linux?

Posted: | Last updated: | 2 minute read

When it comes to managing a Linux system, understanding its hardware resources is crucial for optimal performance. Whether you’re troubleshooting performance issues or just curious about your system’s specifications, knowing how to check your RAM, CPU, and storage in Linux is essential. In this guide, we’ll explore various methods to accomplish this task efficiently.

Checking RAM in Linux

Command Line Methods

One of the simplest ways to check RAM in Linux is by using the command line. You can utilize commands like 'free' or 'top' to display memory usage statistics. For instance, running 'free -h' will provide you with a human-readable summary of your system’s memory usage, including total, used, and available RAM.

GUI Methods

If you prefer a graphical interface, many Linux distributions come with system monitoring tools pre-installed. Applications like GNOME System Monitor or KDE System Guard offer detailed insights into your system’s RAM usage in a user-friendly interface.

Checking CPU in Linux

Command Line Methods

Similar to checking RAM, you can use command line tools to inspect CPU usage in Linux. Commands like 'top' or 'htop' provide real-time data on CPU usage, processes, and system load. Running 'top' in your terminal will display a dynamic overview of CPU utilization and active processes.

GUI Methods

Graphical tools such as System Monitor or System Profiler and Benchmark offer comprehensive CPU monitoring capabilities. These applications present CPU usage graphs, process details, and system load averages in an intuitive graphical interface, making it easier to analyze CPU performance.

Checking Storage in Linux

Command Line Methods

To check storage in Linux from the command line, you can use utilities like 'df' (disk free) or 'du' (disk usage). Running 'df -h' will show you a summary of disk space usage on your system, including the total size, used space, and available space for each mounted filesystem.

GUI Methods

For a graphical representation of storage usage, file managers like Nautilus or Dolphin provide built-in tools to view disk usage. Simply right-click on a folder or drive, select “Properties,” and you’ll see a graphical breakdown of storage usage by file type or directory.

In Linux, monitoring hardware resources like RAM, CPU, and storage is essential for system maintenance and performance optimization. By mastering the various command line and graphical methods outlined in this article, you can efficiently track your system’s hardware usage and ensure smooth operation.


Q1: Can I check hardware resources remotely in Linux?

Yes, tools like SSH (Secure Shell) allow you to access and manage Linux systems remotely, including monitoring hardware resources.

Q2: Are there any third-party applications for hardware monitoring in Linux?

Absolutely, several third-party tools like Glances, Conky, or Grafana offer advanced hardware monitoring capabilities for Linux systems.

Q3: Is there a command to check specific hardware details like RAM speed or CPU model in Linux?

Yes, commands like 'lshw' (list hardware) or 'lscpu' provide detailed information about various hardware components, including RAM speed, CPU model, and more.

Q4: Can I set up alerts for high hardware usage in Linux?

Certainly, you can use monitoring tools like Nagios or Zabbix to set up alerts and notifications for high hardware usage thresholds in Linux.

Q5: Is it possible to upgrade hardware components in a Linux system?

Absolutely, just like any other operating system, you can upgrade hardware components such as RAM, CPU, or storage in a Linux system to enhance performance and capabilities.
