 DSECT NAME - SYTSPT
 FUNCTION - Map a Monitor record.
 LOCATED BY -
        Through the Monitor Control Area
 REFERENCED CONTROL BLOCKS -
        MRRECHDR    Monitor Record Header
 NAME - MRSYTSPT
 DESCRIPTIVE NAME - Monitor Sample Record
                    Domain 0  - System Domain
                    Record 24 - Scheduler Activity per processor
                                type (CP, IFL, zIIP, zAAP, ICF)
 DESCRIPTION - Provides information concerning scheduling
               of work in the system to aid an installation
               in the use of tuning commands. This information
               should be used with records MRSYTSCG (Domain 0,
               Record 10) and MRSYTSCP (Domain 0, Record 13) for
               for a complete picture of scheduling in the system.
               Much of the scheduling of work in VM is done
               according to the type of processor.  One
               of these records is created for each
               processor type.
