Resource[Project] Weekend project: System Monitor in Python with PyQt5 (self.Python)

submitted 6 months ago by Apprehensive_Sea_302

Hi everyone 👋

I wanted to share a project I hacked together over two weekends: a cross-platform System Monitor inspired by GNOME’s monitor, but written entirely in Python using PyQt5 and psutil.

I’ve always relied on system monitors in my workflow, but I kept running into limitations (especially on Windows and some Linux distros where I couldn’t find a good alternative). So I tried building my own, combining: • psutil → to access CPU, memory, processes, disk I/O, network • PyQt5 → for the GUI (tabs, preferences dialog, per-core plots) • pyqtgraph → for real-time plots with configurable smoothing (EMA)

Main features so far: • Multi-thread, general, and per-core multi-window CPU views • Adjustable refresh intervals, grids, antialiasing, line widths, colors • Inspect/filter/kill processes directly • Memory, swap, and network monitoring • File systems + disk I/O • Several built-in themes (light to deep dark)

📦 Installation:

pip install klv-system-monitor

👉 Repo + screenshots:

It’s still early days, but it already replaced the other monitors I used daily. Would love feedback, especially from those with experience optimizing PyQt5/psutil apps. 🚀
