Let the hub learn when a machine reboots.

Work › actions › alerts › scheduled reboots. Learning is on unless you clear it for the machine.

When a machine reboots three or more times, on different days, at about the same local time, the hub adds a window that covers those reboots and marks it learned. It looks back five weeks. A learned window you remove is not learned again from the same old reboots, only from new ones. Clear the box to stop the hub doing this on this machine.

Read the reboot history

Open the machine, then work › actions › alerts. Under reboot history each reboot says whether it was in window or outside any window, and how long the machine was offline. Window learned is the moment the hub switched a window on, with how many reboots it came from. Accounts server rebooted three Sundays in a row before its window was learned.

Reboot history listing reboots outside a window, a learned window, and a reboot in the window — Three Sunday reboots, the window learned from them, and a later reboot inside it.

Stop the hub learning on this machine
