Automated Website Uptime Monitor with Email Alerts
detail.loadingPreview
This n8n workflow automatically monitors the uptime status of multiple websites at a set interval. If any configured website goes down, it promptly sends an email alert to notify you, ensuring you're always aware of your web services' health.
About This Workflow
Never be caught off guard by website downtime again! This powerful n8n workflow provides a robust, automated solution for continuously monitoring the availability of your critical web assets. Scheduled to run hourly, it systematically checks a list of specified URLs. For each website, it performs an HTTP request and intelligently determines its status based on the response code. If a website is detected as unresponsive or returning an error (status code > 400), an immediate email alert is dispatched to your designated inbox, allowing for swift action and minimizing potential impact on your users or business operations. This hands-free solution is essential for maintaining service reliability.
Key Features
- Scheduled Uptime Checks: Automatically monitors websites at a configurable hourly interval.
- Multi-Site Monitoring: Easily configure and monitor multiple website URLs from a single workflow.
- Intelligent Status Detection: Determines website "UP" or "DOWN" status based on HTTP response codes (e.g., <= 400 is considered up).
- Instant Email Alerts: Receives immediate email notifications via Gmail when a website is detected as down.
- Customizable Alert Recipient: Set your preferred email address for receiving downtime alerts.
How To Use
- Configure Websites: In the Config node, update the
Websitesfield with a newline-separated list of the URLs you want to monitor. - Set Alert Email: In the Config node, change the
alert_emailfield to the email address where you wish to receive downtime notifications. - Connect Gmail Credentials: Ensure you have valid Gmail OAuth2 credentials configured in the Send Email Alert node. If not, click on the credentials field, select "Create New," and follow the prompts to connect your Gmail account.
- Set Schedule: The Schedule Trigger node is pre-configured to run hourly, but you can adjust the interval (e.g., minutes, daily) as needed.
- Activate Workflow: Save and activate the workflow to start monitoring your websites automatically.
