EMS output variable unique Key name

edit

Hi, I am trying to control data center IT equipment using EMS in EnergyPlus. When I try to get the temperature of air at the server Inlet, Ta_in and the server power dissipation, Qs_dot, I get an error that unique key name for these output variables are not found. Here is what I am currently using:

EnergyManagementSystem:Sensor,
    Tain,                    !- Name
    Zone Equipment Inlet Node ,  !- Output:Variable or Output:Meter Index Key Name
    ITE Air Inlet Dry-Bulb Temperature;  !- Output:Variable or Output:Meter Name

EnergyManagementSystem:Sensor,
    Q_dot_s,                 !- Name
    Whole Building,          !- Output:Variable or Output:Meter Index Key Name
    ITE Total Heat Gain to Zone Rate;  !- Output:Variable or Output:Meter Name

The errors that I get are:

   **   ~~~   ** Severe  ** Invalid Output:Variable or Output:Meter Index Key Name =ZONE EQUIPMENT INLET NODE
   **   ~~~   ** For Output:Variable or Output:Meter = ITE AIR INLET DRY-BULB TEMPERATURE
   **   ~~~   ** Entered in EnergyManagementSystem:Sensor=TAIN
   **   ~~~   ** Unique Key Name not found.
   ** Severe  ** Invalid Output:Variable or Output:Meter Index Key Name =WHOLE BUILDING
   **   ~~~   ** For Output:Variable or Output:Meter = ITE TOTAL HEAT GAIN TO ZONE RATE
   **   ~~~   ** Entered in EnergyManagementSystem:Sensor=Q_DOT_S
   **   ~~~   ** Unique Key Name not found.

Can someone please help me identify what the unique key name should be for these. I have tried a bunch of combinations but none seem to work.

Thanks in advance.
