MRSYTCUG Prolog

 DSECT NAME - SYTCUG
 FUNCTION - Map a Monitor record.
 LOCATED BY -
      Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
      MRRECHDR    Monitor Record Header
 NAME - MRSYTCUG
 DESCRIPTIVE NAME - Monitor Sample Record
             Domain 0  - System Domain
             Record 15 - Logical CPU Utilization Data (Global)
 DESCRIPTION - Global description of logical CPU utilization in
             a LPAR environment.  This record contains only data
             of global nature and exists only when the system is
             running under control of the PR/SM feature.  For
             descriptions of individual logical partitions and
             their logical CPUs, see the MRSYTCUP (Domain 0,
             Record 16) record.
