Lightweight system monitor for Linux VPS written in Go

Vpsmon is a lightweight system monitor for Linux VPS built in Go that uses only ~5MB of RAM and provides a single binary executable. It monitors CPU, memory, swap, disk, network, uptime, and process count through a web UI with login authentication that auto-refreshes every 5 seconds. Installation and uninstallation are straightforward via bash scripts, with configuration available through environment variables for listen address, username, and password.
