DSECT NAME - SYTSXP FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header 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.
