DSECT NAME - STOSXP FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRSTOSXP DESCRIPTIVE NAME - Monitor Sample Record Domain 3 - Storage Domain Record 20 - 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.
