     NAME - MRSYTSCP
     DESCRIPTIVE NAME - Monitor Sample Record
                        Domain 0  - System Domain
                        Record 13 - Scheduler Activity (Per Processor)
     DESCRIPTION - Describes scheduler activities in a processor.  A
                   separate record is generated for each online processor
                   in the system.
     NOTES:
       - This record should be used in conjunction with record MRSYTSCG
         (Domain 0, Record 10) for a complete description of scheduler
         activities in the system.
