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.
