🖥️ Open-source system performance monitor in C++/Qt6 — real-time, cross-platform, dark & light themes!
Built from scratch as part of the Art2Dec SoftLab open-source initiative. Runs natively on Linux x86_64 and ARM64 (Raspberry Pi 4/5).
✅ CPU monitoring — per-core histogram bars + 60-second history oscilloscope with gradient fill
✅ Memory — color-coded RAM bar (Used / Buffers / Cache / Free) + Swap, live GB stats
✅ GPU auto-detection:
NVIDIA — via nvidia-smi
AMD — via sysfs gpu_busy_percent
Intel — via gt_cur_freq_mhz
Raspberry Pi VideoCore — via vcgencmd
✅ Raspberry Pi specific: SD card / eMMC flash storage monitoring — used & free space, read/write speeds, VideoCore GPU load graph via vcgencmd — works out of the box on Pi 4/5
✅ Disk & Network — dual oscilloscopes with gradient fill, read/write and rx/tx speeds
✅ Hardware info bar — CPU model, RAM size, Disk, Network interface, GPU model — detected once at startup
✅ Full process table with scroll and click-to-sort on any column:
PID · USER · PRI/NI · NAME · CPU% · MEM% · VIRT · RD/s · WR/s · FD · S · START
✅ Top 15 / All processes toggle
✅ Dark / Light theme — switch on the fly
✅ Pause, 1s/2s refresh rate
✅ Single C++ source file, no external dependencies beyond Qt6
Pre-built binaries for Linux x86_64 and ARM64 (Raspberry Pi) included.
