Alerts › scripts. Downtime is the kind for a machine that has stopped reporting. The kind row is the same list as an alert rule. None of them ticked would match every kind, and the hub refuses a trigger that matches every alert.

A desktop that should stay quiet overnight is a different switch. This trigger still matches it until that machine is left out of offline alerts.

Downtime starts ticked, and disk can be ticked too

Clear disk and leave downtime

The key box stays empty, so every downtime alert matches, on every machine. Press save when this is the one you want. This shot stops before that. Cancel drops the draft. Run on is still these machines, and none is ticked, so a save would also need a target.
