Alerts - Logic to limit alerts based on singular failure vs multiple failures?

Hoping someone has had experience with this, im trying to limit the amount of alerts we get based on location for example (as right now it can be a bit overwhelming).

the idea is that a building has 5 switches, one is the “main” switch, where the outside connection comes in and it feeds the other 4 switches, each on a different floor.

So main floor switch, floor 1 switch, floor 2 switch, floor 3 switch, floor 4 switch.

I would like to create rules, so that if an individual floor goes down, we get that alarm, (ie Alert - Floor 4 is down) but if a main switch goes down (taking the whole building with it), I dont get 5 alerts saying main floor down, floor 1 down, floor 2 down, etc. I want to limit it to say “Alert - The whole building appears down” so we know there is a problem but dont get flooded (as right now people ignore/miss alarms as they can get flooded).

Does librenms have a way for me to apply this logic to the alert rules? Do i need to use a external system to do this? Thanks for any ideas or help on this

Yes you need to setup Device Dependencies - LibreNMS Docs

Thanks Kevin
