Health Checks vs Activity Checks

• Health check: requests the form page and verifies the configured selector exists.
• Activity check: looks for recent confirmations and warns if silence exceeds threshold.

Silence alerts are suppressed when health checks are currently failing, so you are not flooded with duplicate root-cause alerts.

How We Determine a Form Stopped Working

• Health check fails if page fetch fails, non-2xx response returns, or selector is not found.
• Activity check warns when time since last confirmation exceeds the silence threshold.
• Recovery is recorded when a previously failing health check returns to pass.

Learning Mode

New forms start in learning mode (default window: 7 days). During this period FormPulse looks at confirmation timing and computes a recommended threshold.

• With 3 or more confirmations, FormPulse uses the 90th percentile gap and a sensitivity multiplier.
• With low activity (1-2 confirmations), a conservative threshold is used.
• With no confirmations, a learning alert is created so you can investigate and optionally extend learning.

Once learning completes successfully, the recommended threshold is auto-applied and monitoring becomes active. Once learning mode is complete, the system will continue to monitor for any sudden changes in activity and suggest a new threshold if needed.

Rate Limiting

To protect your data from spikes or spam, inbound confirmations are rate limited per form. If a form receives more than 100 confirmations in an hour, additional inbound events are ignored for that hour.

This helps keep analytics stable and prevents abuse from overwhelming the system.

Check Intervals

New checks are created with a default interval. After learning computes a threshold, the activity check interval is recalculated to approximately one quarter of that threshold (minimum 60 minutes), so the system checks multiple times before the threshold is exceeded.
