vpsmon

Lightweight system monitor for Linux VPS. Single Go binary, ~5MB RAM usage.

Monitors CPU, memory, swap, disk, network, uptime, and process count. Web UI with login, auto-refreshes every 5 seconds.

Deploy

./deploy.sh

The script will ask for VPS connection details and web UI credentials, then build, upload, and install as a systemd service on port 8088.

Environment Variables

Variable	Default	Description
MONITOR_ADDR	:8088	Listen address
MONITOR_USER	admin	Web UI username
MONITOR_PASS_HASH	(hash of changeme)	Web UI password (bcrypt hash)

Password Hashing

For security, the password is not stored in plaintext. You must provide a bcrypt hash via the MONITOR_PASS_HASH environment variable. The deploy.sh script handles this automatically during setup.

If you need to generate a hash manually, you can run the binary with the -hash flag:

./vpsmon -hash "my_secure_password"
