The 5 key toggles the top bar, which displays details about CPU, memory, and load. The 4 key toggles everything but the “quick look” and load displays on the top bar. The 3 key toggles the “quick look” block on the top bar, which provides a graphical summary of CPU and memory usage. The 2 key toggles the left side bar, which, by default, includes network, file usage, and sensor information, among others.

Once you have filtered the processes, you can press Enter again to edit your filter or press E (case sensitive) to reset the filter. This includes any modules you’ve set up using the Glances configuration file, which you can learn more about in the Example Configurations section below: glances You can open up the default glances view with the basic command alone. Afterward, you’re ready to start using Glances and dive deeper into tuning it precisely to fit your needs. The next few sections walk you through some of these options, aiming to get you started with the most useful of them as a foundation. But you can also take advantage of Glances’ options, from interactive commands, to client–server arrangements, to fine-grained configurations. How to Use Glances System MonitoringĪt its simplest, you can immediately start using Glances to monitor your local system. However, it doesn’t require you to have installed any of the other dependencies listed in the Glances README. The rest of this guide assumes that you’ve installed all of the modules, using the glances command above. You can also use the command below to get a full list of Glances modules: glances -modules-list You can get a full list of these dependencies on the README for Glances. Some of these modules require you to install other dependencies on your system. So, to install the modules for the folders section, the GPU display, and the web server, you can use: pip3 install -user glances To install select modules only, use the same command, but replace all with the name of each module you want, separating modules with commas. To install all of the optional modules, use the following command: pip3 install -user glances You have two options if you want to install these: Glances has numerous modules to enable optional features. You can then verify your installation with: glances -version You may need to either restart your shell session (logging out and logging back in) or run the command below for the glances command to become available: source ~/.bashrc Install Glances using the Pip package manager: pip3 install -user glances On Fedora, use: sudo dnf install python3 python3-pip python3-devl On AlmaLinux and CentOS, use: sudo dnf install python3 platform-python-devel On Debian and Ubuntu, use: sudo apt install python3 python3-pip python3-dev Install Python 3 (if it isn’t already installed), along with the Pip package manager, and the Python developer package. These features make Glances ideal for monitoring your system remotely and having all the system information you need immediately available. Or you can run it as a web server, which you can access from a web browser on the local or a remote machine. You can run Glances as a simple server, which you can access from another machine. bottom, while providing more information than gtop, prioritizes customization over efficiency of the display. gtop, in contrast, gives a minimalist display, focusing only on key pieces of information. Glances sets itself apart primarily in two ways.įirst, it aims to efficiently display as much information as reasonably possible at one time. You can learn more about these last two in our guides How to Install and Use gtop on Linux and How to Install and Use bottom on Linux, respectively.
