We have an Orion instance in Chicago that monitors network and server hardware at our India offices in Bangalore.
The circuit is managed by a redundant pair of Cisco ISR 4451 routers.
When this circuit has severe degredation or drops due to vendor issues, our Bangalore managed nodes all bark.
In order to address this, I added the Bangalore nodes to a group (as the child) and then added both representations of the internet circuit from each of the ISR routers to a group (as the parent).
The ISR circuit group is set to reflect worst child status, so it should go critical if either managed interface in the HA pair goes down or packet loss is critical.
Since I'm not too familiar with using groups as dependencies, I wanted to get advice on whether or not this should work as intended.
