MRSYTPOW Prolog

 DSECT NAME - SYTPOW
 FUNCTION - Map a Monitor record.
 LOCATED BY -
        Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRSYTPOW
 DESCRIPTIVE NAME - Monitor Sample Record
                    Domain 0  - System Domain
                    Record 25 - Power Consumption Data
 
 DESCRIPTION - Physical LPAR (and possible CEC) data for
               accumulated power consumption
 
 NOTES:
  -- This record is generated only when power data
     collection is available to the hypervisor.
 
  -- When the HMC Global Performance Data setting is disabled,
     only power data about the current LPAR is returned.
     When the setting is enabled, power data about the LPAR
     and the CEC are returned.
