Configuring Monitor Alerts and Notifications

Get notified when your monitors detect downtime.


Monitor-Specific Alerts

From the monitor detail page, configure alerts to fire when:

  • The monitor goes DOWN (endpoint returns non-200 or times out)
  • Response time exceeds a threshold (e.g., > 2 seconds)
  • The monitor has been down for a duration (e.g., > 5 minutes)

Notification Channels

Monitor alerts use the same notification channels as log alerts:

  • Email — send to one or more email addresses
  • Webhooks — POST to any HTTP endpoint

Configure channels in the alert settings.

Flapping Prevention

If an endpoint is intermittently up and down (flapping), Lognitor automatically adjusts:

  • Requires multiple consecutive failures before firing an alert
  • Sends a "recovered" notification only after multiple consecutive successes

This prevents notification spam from unstable connections.

Monitor your health endpoint

Create a /health endpoint that checks your database, cache, and external dependencies. Monitor that endpoint for a comprehensive availability check.
