Monitor types
- Website: status code and optionally a phrase that must (or must not) be on the page.
- SSL certificate: invalid or expiring within the warning window (14 days by default).
- Domain expiry, Port and Heartbeat (a private ping address your scheduled jobs call).
Incidents
A failed check is retried after 2 seconds before it counts. An incident opens after the number of failures in a row you choose (2 by default) and closes on the next successful check. Alerts go to the bell, by email and to an optional webhook, with a cooldown against repeats.
Maintenance
Schedule a window in UK time: checks keep running but no incidents or alerts are raised, and the status page shows the maintenance.
Check your understanding
A check fails once, then passes on the retry 2 seconds later. What happens?
Status page
Publish a branded page with your logo, colours and chosen monitors. Visitors can subscribe by email to incident updates. Password, custom CSS and hiding Powered by Serpfull on every plan.
