TopHat is an elegant system resource monitor for the GNOME shell. It displays CPU, memory, and network activity in the GNOME top bar.
- GNOME 3.38 or newer
- The gtop system monitoring library (e.g., 'libgtop' on Debian-based systems, likely already installed as part of GNOME)
- GIRepository (gir) bindings for the gtop system monitoring library (e.g., 'gir1.2-gtop-2.0' on Debian-based systems)
- CenOS Stream 9
- Debian 11.3
- Fedora 36
- Ubuntu 22.04 LTS
To view logged output, use the command journalctl -f -o cat /usr/bin/gnome-shell.
To simulate heavy system load, use the stress-ng tool, e.g. stress-ng --timeout 10s --cpu 8.
To install manually:
mkdir -p ~/.local/share/gnome-shell/extensions/
ln -s [path to tophat repository] ~/.local/share/gnome-shell/extensions/[email protected]
