To reduce false positive alerts, InfraBeacon checks again before marking your site as down. You can adjust this with the fault tolerance setting.
The confirmation process
- Initial failure detected - A check returns an error or timeout.
- Local confirmation - The system retries the check from the same location.
- Remote confirmation - If local checks still fail, the system checks from more locations.
- Downtime confirmed - After confirmation, the site is marked as down and an alert is sent.
Fault tolerance presets
Choose a preset that matches your needs:
- Low - One retry. Alerts are sent quickly, but brief network issues may cause more false positives.
- Medium (default) - Several retries. This is a good choice for most sites because it balances speed with fewer false positives.
- High - More retries. This reduces false positives, but real outage alerts may arrive later. It is useful for sites with occasional network issues.
Balancing speed vs accuracy
Lower fault tolerance means faster alerts, but more false positives. Higher fault tolerance means fewer false alerts, but slower alerts for real outages. Choose the option that feels right for each monitor.
