I just can't seem to recall how to suppress the alerts generated from down stream devices.
The feature is called dependencies, you define a parent and children and if the parent goes down then orion stops polling all the children. Can do 1 to 1 relationships, or use groups to do 1 to many or many to many, or many to 1 (but that last one is probably uncommon)
Ok, How do I create the dependencies?
I found it. Thank you!
