Building a Real-Time Server Monitor with Raspberry Pi

A step-by-step breakdown of how I built a real-time monitoring system using Raspberry Pi, Telegram alerts, and custom automation tools — designed to track server activity, temperature, and security events.

What I Wanted to Build

As someone who loves servers, automations, and smart tools, I wanted a lightweight system that could monitor everything happening in my home setup — from Raspberry Pi temperature to SSH attempts and service uptime.

Core Features

  • Real-time temperature monitoring

  • Automatic alerts via Telegram

  • External IP change notifications

  • Service status checks (Nginx, Docker, WireGuard)

  • Daily logs with historical data

Tools I Used

  • Raspberry Pi 4

  • Python Telegram Bot API

  • Crontab for scheduled checks

  • Shell scripts for server status

  • CasaOS for container management

How It Works

Every few minutes, my Pi runs a set of scripts that gather metrics from the system. These metrics are instantly pushed to my Telegram bot using Python.
If something goes wrong — like high temperature or too many invalid SSH attempts — I get an alert right away.

Why I Built It

I wanted a personal dashboard that feels futuristic, clean, and useful — something that matches the cyber aesthetic of my workflow while giving real value and control over my server environment.

What’s Next

I plan to integrate:

  • live graphs

  • GPU/CPU usage tracking

  • a full Agent Emergency Dashboard UI

  • mobile-friendly controls
