Hello,
I want to know the amount of Energy used by the system over a period of time, which is usually measured in Joule (1 Joule = 1 Watt for 1s).
I see that there are counters related to current power usage in the schemas, like "Power consumption (W)".
However, power consumption varies over time, so knowing that the current power draw is 453W right now, and was 827W 10min ago is not enough to compute the energy: I have no information as to when it dropped, was it 5s ago or 9min ago ?

As to give you an example, on NVIDIA GPUs, the API has a nvmlDeviceGetTotalEnergyConsumption() call for this purpose.
The documentation says: "Retrieves total energy consumption for this GPU in millijoules (mJ) since the driver was last reloaded".
I can query it twice, compute the difference, and tell how much was used during the experiment.
Where I should look at ? Or given I'm especially interested in Dell iDRAC at the moment, are there extensions you are aware of, that could be useful for my research ?
Thanks,
