Host Parents = Service(s) from other hosts
In terms of infrastructure monitoring which is psychical, it would greatly benefit to be able to set the parrent of "PC_1" as being "Switch_1"--"Interface 5"
For the cases where a port/interface is allocated to a certain device, at the moment we are getting 2 or more alerts due to this behavior, and building BI rules for 5000 hosts is not something to consider.
