Alerting
exit1.dev provides multi-channel alerting to keep you informed when your checks change status.

How Alerting Works
- A check runs and detects a status change (e.g., up to down)
- Smart verification re-checks after 30 seconds to confirm
- The consecutive failure threshold is evaluated
- If the threshold is met, alerts are dispatched to all configured channels
- When the check recovers, recovery alerts are sent
Flap Suppression
To prevent alert fatigue from flapping services (rapidly alternating between up and down), exit1.dev uses the minConsecutiveEvents setting. This requires a minimum number of consecutive events before triggering an alert, reducing noise from unstable endpoints.
Alert Configuration
Alerts can be configured at two levels:
- Account level - Default alert settings applied to all checks
- Per-check level - Override settings for individual checks
Check Severity (P1–P5)
Each check has a severity from P1 (Critical) to P5 (Minimal), set with a slider under Alert behavior in its settings. Severity lets channels that support notification priority treat important sites differently from low-stakes ones — page me for a P1 outage, stay quiet for a P5 dev box — without configuring separate integrations. Today severity drives Pushover priority.
The slider sits behind a Use default priority switch that is on by default, so a new check inherits whatever priority its integrations are configured with. Turn the switch off to set an explicit severity, which then becomes a hard ceiling on every alert that check sends — including outages. That makes P3 a real choice (“tell me, but never interrupt me”), not a neutral one; leave the switch on if you want an outage to keep its usual High floor.
Whatever you pick, a recovery notification is always capped below the level that bypasses do-not-disturb. Coming back up is never urgent.
