Device_dependencies

Help

device_dependencies items missing to create alert rules.

wanted to create below rule but find out that there is no device_dependencies in database.

devices.status = 0 AND devices.disabled = 0 AND devices.dependency_parent IS NULL

was it not supposed to be created automatically after creating sites parents ?

Device dependencies don’t work for normal alerts. Only up/down alerts when using fast ping.

I need to make it work to reduce floods of alarms. Kindly share any information to create devices dependencies rules.
