Description
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.
