question about InputPowerWatts in PowerSupplyMetrics schema

Hello,

We're looking for a way to reliably total all power consumed by a server. With the Power schema deprecated (as of v1.7 2020.4), checking the PowerSubsystem schema (v1.1 2021.2), it has the property PowerSupplies, defined in the "Redfish Resource and Schema Guide", 2024-04-04 version 2024.1 (DSP2046_2024_1.pdf) "Link to Collection of PowerSupply. See the PowerSupply schema for details." Checking the PowerSupplyMetrics schema: redfish.dmtf.org/schemas/v1/PowerSupplyMetrics.v1_1_2.json , it includes the definition, "InputPowerWatts", below: 


"InputPowerWatts": {
"anyOf": [
{
"$ref": "http://redfish.dmtf.org/schemas/v1/Sensor.json#/definitions/SensorPowerExcerpt"
},
{
"type": "null"
}
],
"description": "The input power (W) for this power supply.",
"excerptCopy": "SensorPowerExcerpt",
"longDescription": "This property shall contain the input power, in watt units, for this power supply. The value of the `DataSourceUri` property, if present, shall reference a resource of type `Sensor` with the `ReadingType` property containing the value `Power`."
}

Is this InputPowerWatts metric intended to represent the total power consumed by a power supply, inclusive of everything, or is anything omitted? If the InputPowerWatts metric is intended to capture all power used by a power supply, then would totalling InputPowerWatts over the collection of power supplies for a server, provide a complete total of all power consumed by the server, or would anything be left out? 

Is there an overall total metric representing the total power consumed by a server (other than totaling power over the power supplies, assuming that is a valid way to calculate total power consumed)?

Thank you,
