Multiple trigger dependencies but with diferent hosts

[FranD]

Hi all,

We are using Zabbix to monitor the network of hundred of our offices. This means, that each office has its own router, a few switches, and also a couple of acces points.

We are working in prevent event storms, and I'm fighting with the trigger dependencies to make it work. I know that we can add a dependency to a trigger attached to another host's trigger, but how can we do this massive with diferent hosts?

For example:

Office 1:

Router 1 - Switch 1 - Switch 2 - Access Point 1 - Access Point 2

Office 2:

Router 2 - Switch 3 - Switch 4 - Access Point 3 - Access Point 4

Using default "ICMP Template", I want that the trigger "Host Down" on Switch 1, Switch 2, AP1 and AP2 depends on Router 1's trigger "Host Down".

Same for the office 2, but with Router 2. I don't want a relationship between offices. I can make it manually if we have 5 o 6 offices, but unfortunately we have hundreds, so, anyone knows how to make it massive? Is it even possible?

Sorry if it's a dumb question. Any help is appreciated. Thanks.

Kind Regards.
