This setting allows you to ignore notifications for downtimes that are smaller than X minutes ( X being the value that you select here ).

Let’s say you don’t want to be notified of downtimes smaller than 5 minutes, simply select “Alert me after 5 minutes of downtime”, now this uptime monitor will only send online/offline alerts for downtimes bigger than 5 minutes; any downtime smaller than 5 minutes will not trigger any notifications.



This setting only applies to notifications, which means all downtimes that occur will still be logged into your uptime reports, regardless of their length.

This setting has no effect if your uptime monitor has no contact list assigned to it, as in this case no notifications are ever sent out.
