 DSECT NAME - SYTSYG
 FUNCTION - Map a Monitor record.
 LOCATED BY -
        Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRSYTSYG
 DESCRIPTIVE NAME -  Monitor Sample Record
                     Domain 0 - System Domain
                     Record 19- System Data (Global)
 DESCRIPTION - System wide utilization data.
 NOTE:
   -- For additional information about the format and
      meaning of the SYTSYG_SSIxxxxx fields, refer to
       - Principles of Operation for the layout of the
         STSI output (SYSIB 1.2.2 and 2.2.2) which is
         documented in Chapter 10 under "STORE SYSTEM
         INFORMATION".
   -- When a field in this record uses the term "CPU/core",
      the meaning of the field changes based on whether
      Multithreading (MT) is enabled for this partition.
      Refer to Monitor Sample Record Domain 1 Record 4
      (MRMTRSYS) to determine whether MT is enabled for
      this partition as well as the number of threads for
      each CPU type.
       When MT is not enabled, a physical core contains
       only one CPU:
         - CPU   : central processing unit.
         - CORE  : physical unit containing one CPU.
                   In this environment the core has
                   1 thread, the term "thread" is not used,
                   and the term "CPU" is generally favored
                   over the term "core".
       When MT is enabled, a physical core contains one or
       more CPUs (aka "threads"):
         - CPU   : central processing unit. Identified by
                   CPU address which consists of core ID
                   and thread ID.
         - CORE  : physical unit containing one or more CPUs
                   (aka "threads"). All CPUs of a core have
                   the same CPU type.
         - THREAD: synonym for a CPU that is a member of a
                   core. Each thread on a core has a
                   distinct thread ID (TID), numbered from
                   0 up to the maximum thread ID available
                   on the core.
