Can you ask each tower and each PDU fo ran overall status? Like 'I'm all good' or 'There are some problems'? What I'm thinking is a two fork approach, one deals with the status of the devices, and a second set to deal with which phase on which tower went down. Since you don't care at the PDU level what phase went down, don't ask. (even if you use 1 PDU to monitor the individual legs for that)

You are correct though each PDU has 2 3Phase towers. One that is dedicated straight to city and the other to the UPS. All my servers that run dual power will be fine, however a few things do not. The concern was what happens is the UPS dies(I know sounds odd but it has happened here before apparently) What I am looking for I think ultimately would be helpful for other things as well. For instance – If I had a group of 6 temperature sensors that check different parts of a data center. And 3 of them went down I would want to know that the group was bad then and possibly our AC went out. But if just one went high it could be a fluke. I would not however want 6 pages when they all went down. Does that make sense?

One connected to each Tower? If you lose City power, does a server go DOWN? Michael D.

The UPS is rather old and the SNMP monitor for it is not yet working. My Current SAlive Config(Per PDU): PDU Ping Check Sub-Group – Tower A(City) Tower A Leg 1 SNMP Check – Dependent on Ping Check Tower A Leg 2 SNMP Check – Dependent on Ping Check Tower A Leg 3 SNMP Check – Dependent on Ping Check Sub-Group – Tower B(UPS) Tower B Leg 1 SNMP Check – Dependent on Ping Check Tower B Leg 2 SNMP Check – Dependent on Ping Check Tower B Leg 3 SNMP Check – Dependent on Ping Check I do this for each PDU, I will then know if each leg has problems(not a huge issue so I am not pressed but it is what I can do). The problem becomes that I can not check an entire leg. So if power drops then I would get 3 pages from each PDU. I have even thought about grouping all the city and all the UPS but I need a way to pass an alert if a group fails. Does that explain my situation better?

If this is what you want to do, full instructions are in the user guide. If you're looking for something else, please explain further. Michael D.

Heres the scenario. Any suggestion would be helpful. I really would like a single page is all of City power drops, not one per PDU. Each Rack 1 PDU(with SNMP Monitoring)208 - Three Phase Power Each PDU 2 Towers – 1 for City Power, 1 for UPS Power( Can be checked independent) Each Tower 3 Phases(Can each be checked individually) Right now I have each phase set to send an email and each tower, and if a ping against the PDU fails. The phases are dependent upon their tower and the tower upon their PDU but that still leaves a page for each PDU if I lose City or UPS power for some reason.
