Automated website uptime monitor with email alerts & GitHub status page update

Automated Website Uptime Monitor with Email Alerts & GitHub Status Page Update This n8n workflow continuously monitors your website’s availability, sends email alerts when the server goes down, and automatically updates a status page (index.html) in your GitHub repository to reflect the live status. --- 📌 Good to Know - The workflow checks your website every 2 minutes (interval configurable). - If the website is down (503, bad response, or error) → it sends an email alert and updates the GitHub-hosted status page to show Down. - If the website is up (200) → it updates the GitHub-hosted status page to show Up. - The email notification includes an HTML-formatted alert page. - You can use GitHub Pages to host the status page publicly. ℹ️ What is GitHub Pages? - GitHub Pages is a free hosting service provided by GitHub that lets you publish static websites (HTML, CSS, JS) directly from a GitHub repository. - You can use it to make your index.html status page publicly accessible with a URL like: ⚡ How to Set Up GitHub Pages for Your Status Page 1. Create a new repository on GitHub (recommended name: status). 2. Add a blank index.html file (n8n workflow will later update this file). 3. Go to your repository → Settings → Pages. 4. Under Source, select the branch (main or master) and folder (/root). 5. Save changes. 6. Your status page will now be live at: ✅ Prerequisites - An n8n instance (self-hosted or cloud). - A GitHub account & repository (to host the status page). - A Gmail account (or any email service supported by n8n – example uses Gmail). - Access to the target website URL you want to monitor. --- ⚙️ How it Works 1. Schedule Trigger → Runs every 2 minutes. 2. HTTP Request → Pings your website URL. 3. Switch Node → Evaluates the response status (200 OK vs error/503). 4. Code Node → Generates a dynamic HTML status page (Up/Down). 5. GitHub Repo & File → Github Repo Name Should be (recommended) & Must have(required) a blank file named as index.html before triggering this flow. 5. GitHub Node → Updates/commits the index.html file in your repository. 6. Gmail Node → Sends an email alert if the site is down. --- 🚀 How to Use 1. Import the workflow JSON into your n8n instance. 2. Configure credentials for: - GitHub (Personal Access Token with repo permissions). - Gmail (or your preferred email service). 3. Replace the following: - → with your own website URL. - example@gmail.com → with your email address (or distribution list). - GitHub repo details → with your repository where index.html will live. 4. Deploy the workflow. 5. (Optional) Enable GitHub Pages on your repo to serve index.html as a live status page. --- 🛠 Requirements - n8n v1.0+ - GitHub personal access token - Gmail API credentials (or SMTP/email service of your choice) --- 🎨 Customising this Workflow - Interval → Change schedule from 2 minutes to any desired frequency. - Email Content → Modify HTML alert template in the Gmail node. - Status Page Styling → Edit the HTML/CSS in the Code node to match your branding. - Error Handling → Extend Switch node for other status codes (e.g., 404, 500). - Multiple Websites → Duplicate HTTP Request + Switch nodes for multiple URLs. --- 👤 Who Can Use It? - DevOps & SRE Engineers → For automated uptime monitoring. - Freelancers/Developers → To monitor client websites. - Startups & SMEs → For a free, lightweight status page without paid tools. - Educators/Students → As a hands-on learning project with n8n. --- 🌟 Key Features - 🔄 Automated uptime checks (configurable interval). - 📧 Email notifications on downtime. - 📝 Dynamic HTML status page generation. - 🌍 GitHub Pages integration for public visibility. - ⚡ Lightweight & cost-effective (no paid monitoring tool needed). --- 🔗 Tools Integration - n8n – Orchestration & automation. - GitHub – Version control + hosting of status page. - Gmail – Email notifications. - HTTP Request – Website availability check. --- 📈 Example Use Cases - Personal website monitoring with public status page. - Monitoring SaaS apps & notifying support teams. - Internal company services uptime dashboard.
