Vitals is a GNOME Shell extension for displaying your computer's temperature, voltage, fan speed, memory usage, processor load, system resources, network speed and storage stats in your GNOME Shell's top menu bar. This is a one stop shop to monitor all of your vital sensors. Vitals uses asynchronous polling to provide a smooth user experience.


1) Install these packages


apt install gir1.2-gtop-2.0 lm-sensors


dnf install libgtop2-devel lm_sensors


sudo pacman -Syu libgtop lm_sensors gnome-icon-theme-symbolic

2) Install from

3) Activate after installation

Restart GNOME Shell (Alt+F2, r, Enter) and enable the extension through gnome-tweak-tool.

Beta testing

Advanced users requesting bug fixes or asking for new features may occasionally be asked to help QA.

1) Remove existing copy of Vitals

Check to see if ~/.local/share/gnome-shell/extensions/ exists, and if so, remove the directory.

I am hesitant to give an rm command here, in case someone copies and pastes it incorrectly. Again, beta testing is for advanced users so if you don't know how to remove a directory, please stop here.

2) Clone from GitHub

mkdir -p ~/.local/share/gnome-shell/extensions
git clone ~/.local/share/gnome-shell/extensions/

3) Check out develop branch

cd ~/.local/share/gnome-shell/extensions/
git checkout develop


Vitals was originally forked from gnome-shell-extension-freon. I was having trouble finding an up to date, resource friendly and fully featured system monitoring tool. My biggest pet peeve was random system delays becaus of I/O blocking polls, and thus, the idea for Vitals was born! It has been refactored several times over, so most of the code is new or different.


  • (voltage|fan)-symbolic.svg - inherited from Freon project.
  • (system|storage)-symbolic.svg - from Pop! OS theme.
  • temperature-symbolic.svg - iconnice studio.
  • (cpu|memory)-symbolic.svg - DinosoftLabs.
  • network*.svg - Yannick Lung.
  • Health icon - Dod Cosmin.


Sensor data is obtained from the system using hwmon and GTop. Core Coding and the Vitals authors are not responsible for improperly represented data. No warranty expressed or implied.

Development Commands

  • Reload extension gnome-shell-extension-tool -r
    • Note: This command is no longer supported as of GNOME 3.34
  • Launch preferences gnome-shell-extension-prefs
  • View logs journalctl --since="`date '+%Y-%m-%d %H:%M'`" -f | grep Vitals
  • Compile schemas glib-compile-schemas --strict schemas/
  • Compile translation file msgfmt vitals.po -o
