We don't have PDUs pluged into other PDUs but a similar situation as you
described: Our servers/switches/routers are plugged into PDUs on the right
or left side of the rack (without a rackspace) and connected to several
large UPS. It would be great if we could summarize power consumption of the
several power supplies per UPS!
We have created PDUs with as many out ports as in real and linked every
power supply to their connector. Every PDU has one AC-IN-Link to one Port
(Fuse) of the UPS. Every UPS and every PDU is tagged with the same tag the
corresponding UPS has. So we can track connections and filter object list
for all PDUs of one UPS.
First Question: How do you "mount" your "zero-U-PDUs" in RackTables? (to
link/show them in their rack)
Second: I thought about adding a row 'powerconsumption' to the table 'Port'
and enhance the ports-tab of the object page to define the power
consumption of every power supply and to sum up the current for every UPS.
Or do you think there is a better way?
