##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.
