Host your own Uptime Monitoring with Scheduled Triggers

This n8n workflow demonstrates how to build a simple uptime monitoring service using scheduled triggers.

Useful for webmasters with a handful of sites who want a cost-effective solution without the need for all the bells and whistles.

How it works

• Scheduled trigger reads a list of website urls in a Google Sheet every 5 minutes
• Each website url is checked using the HTTP node which determines if the website is either in the UP or DOWN state.
• An email and Slack message are sent for websites which are in the DOWN state.
• The Google Sheet is updated with the website's state and a log created.
• Logs can be used to determine total % of UP and DOWN time over a period.

Requirements

• Google Sheet for storing websites to monitor and their states
• Gmail for email alerts
• Slack for channel alerts

Customising the workflow

Don't use Google Sheets? This can easily be exchanged with Excel or Airtable.
