High level overview

Monitoring uptime

This package can monitor the uptime of sites, api endpoints, or anything that communicates over http or https. To create a monitor use the monitor:create command. This will create a row in the monitors table.

The monitor:check-uptime task should be scheduled to run every minute. When it runs it will send a request to the url of every configured monitor. The package can perform requests concurrently, so don’t be afraid to configure a large number of monitors.

If a request succeeds the Spatie\UptimeMonitor\Events\UptimeCheckSucceeded-event will fire. The uptime of the monitor will be checked again when monitor:check-uptime runs after the interval set in the uptime_check_interval_in_minutes key in the config file.

When an uptime check fails the uptime check for that monitor will be performed any time monitor:check-uptime runs regardless of the value configured in uptime_check_interval_in_minutes.

If an uptime check fails consecutively more times than the value you set in fire_monitor_failed_event_after_consecutive_failures the Spatie\UptimeMonitor\Events\UptimeCheckFailed event will fire.

If an uptime check is successful after failing, the Spatie\UptimeMonitor\Events\UptimeCheckRecovered will be fired.

Monitoring SSL certificates

The package can verify if the ssl certificate of a monitor is valid. By default all monitors whose url starts with https will be checked. This is done by the monitor:check-certificate command which should be scheduled to run daily at least.

When a valid certificate for a monitor is found the Spatie\UptimeMonitor\Events\CertificateCheckSucceeded event will fire. If no valid certificate is found, the Spatie\UptimeMonitor\Events\CertificateCheckFailed event will be unleashed!

If a valid certificate is found, but it will expire in less days than the value set in fire_expiring_soon_event_if_certificate_expires_within_days the Spatie\UptimeMonitor\Events\CertificateExpiresSoon event is fired.
