Service Health Monitoring with Double-Verification & Slack Alerts

How it works
This workflow checks the health of your web services or APIs on a schedule, prevents false alerts with a second verification, and sends confirmed failure alerts directly to Slack.

Performs scheduled HTTP health checks
Waits and retries before confirming failure
Sends alerts only if the service fails twice in a row
Reduces false positives and avoids alert fatigue

Setup steps
Add your service URL(s) in the HTTP Request nodes
Configure your Slack Bot Token in n8n
Deploy the workflow
Get real-time Slack alerts when services go down 🚨

Use case
Perfect for IT teams, DevOps engineers, and developers who need reliable uptime monitoring without noise.
