     NAME - MRSYTSXP
     DESCRIPTIVE NAME - Monitor Sample Record
                        Domain 0  - System Domain
                        Record 22 - System Execution Space
                                    (Per Processor)
     DESCRIPTION - Utilization of System Execution Space storage on a
                   per processor basis.
                   This record is needed because System Execution Space
                   usage is not expected to be evenly distributed across
                   all processors in a complex. A separate record is
                   generated for each online processor.
