Hmm. Indeed this isn't possible. I've wondered a few times how to do something like this, but the identifiers are all so arbitrary I'm not sure how one would do it without it being a royal pain in the arse to configure (and a significant chunk of complex code to maintain).
I do want to give the ability to pass data to external scripts to let people write their own checker code, but I'm not entirely sure how best to go about that yet either (this is actually the problem with ~80% of observium features we want to add!)

Alerts can¹t be added up. They¹re attributed to whatever entity/device/metric combination you create, triggering on the individual values that match your rules.
You could create rules to match both of your individual PDUs, or all PDUs, but you can¹t ask it to add/subtract the values of multiple rules or metrics to trigger an alert.
Curious - what kind of scenario are you looking at that would warrant this kind of alarm?

Is there a way to add PDU Amerage together so you get an alert based on the Amperage Usage of 2 PDUs together?
For Example: PDU A - 10 Amps PDU B - 1 Amps
If PDU A + PDU B = 12 Amps then Send Alert
Something like that.
