Dependencies or Parent/Child Relationships
Allow devices to be dependent on one another. If a router goes down, the switch behind it will most likely go down or have an error as well.

Hmm... This doesn't seem to be working for me. It appears to be; up until the point an alert fires.
I've set a group that has the depends_on property set. Then have placed all relevant devices into said group (same upstream device). Everything appears to be working as expected. I see all devices in the group have inherited the depends_on property. And when I look at the primary device, it has indeed got the is_primary_device = true property set. However, when I kick off a test alert for PingLossPercent on the primary device, none of the dependent devices are put into SDT.
Upon investigation I found that the is_primary_device property was removed from the primary device. And, with the test alert still active, when I poll now from one of the dependent devices, I see it get recreated briefly but then disappear again. Once the alert clears, I am able to poll now from a dependent device and see the is_primary_device property get recreated.
