Hi,
I am trying to run a report from DCE to show how much power the data center has been using over a set period. I have created on for a month and set it to 30 minute intervals. The Data which has been produced is massively high.
First report is done in kWh - This screenshot is for 1 PDU, I have a total of 46 PDUs.
I have a virtual sensor which shows the data center running at 868,827.7 kWh.
I have a second sensor which shows the usage in amps. 166.3A
This data seems massively incorrect, can someone explain to me what is happening and why I am seeing such high results?
I have to run this report for 2 data centers, one for a 12 month period, and one for 5 months.

Hi Martin,
Kwh or kilowatt hours is already a value for power over time. That value on the PDU will continually increase over time. Your actual output at any specific time could actually be 0 watts but the kwh reading could still be high. Here's an example:
One issue that I do see with this value coming from the PDU is that it does not show the date it was reset. If you actually look at the PDU using SNMP (I have a modular PDU to look at for this), you can see the kwh "reset" date. The value you're reading for kwh is what the PDU has used since that time:
If you are looking for a value to match up with amperage, watts would be the value you're looking for.
Thanks,
Steve

So to confirm some understanding, when you run the Summary kWh report, you would take the delta value column and total that up to get your total consumption and in the case of the attached screenshot that would be consumption for the day??
