What is sysmon?

sysmon is a lightweight browser-based tool for watching servers and headless Raspberry Pi devices. It shows live CPU, memory, disk, network, sensor, and thermal data through a web page. Users can stop, force-stop, pause, and restart processes from afar. Built with Python Flask and psutil, it provides 21 color themes, report printing, and adjustable refresh rates. Install via Python virtual environment, x86_64 binary, or systemd service. GPL-3.0 licensed at v0.1.0; authentication and dark mode are not yet implemented.

Should you self-host sysmon?
