Architecture

jdSystemMonitor is made of 2 parts:

• A Daemon written in Go (you can find the source in the daemon directory)
• A Qt6 GUI written in C++ (you can find the source in the gui directory)

Dependencies

jdSystemMonitor requires the following to run:

• Qt6 (Core, Gui, Widgets, DBus, Charts, Xml)
• xdg-desktop-portal
• A Icon theme (only needed if you want to have icons)
• Polkit (pkexec must be in PATH)
• xdg-dbus-proxy (must be in PATH)
• sudo (must be in PATH)

The following dependencies are optional:

• PackageKit for listing all installed native packages

For building jdSystemMonitor from source the following is required:

• Go
• A C++ 23 Compiler (e.g. gcc or clang)
• Meson
• Ninja
• Qt6 Tools
• Gettext
• Python

Building

Meson is used to build jdSystemMonitor

mkdir -p build
cd build
meson setup ..
meson compile

Now you can run ./gui/jdsystemmonitor

Testing the Daemon

If you want to test the Daemon without the GUI, you should use jdDBusDebugger. Run the Daemon directly from the build directory with ./daemon/jdsystemmonitor-daemon --enable-debug-auth. The default D-Bus service name of the Daemon is page.codeberg.JakobDev.jdSystemMonitor.Daemon. Open the Service in jdDBusDebugger and execute the DebugAuthentication method. Now you should have access to all the functions of the Daemon.

Testing the GUI

You can directly run ./gui/jdsystemmonitor in the build directory. This will automatically connect to the Daemon from your build directory.

Custom URL Schema

jdSystemMonitor provides a custom jdsystemmonitor: URL scheme for integration into other Apps. The following options are currently available:
