MRSTORSP Prolog
DSECT NAME - STORSP
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRSTORSP
DESCRIPTIVE NAME - Monitor Sample Record
Domain 3 - Storage Domain
Record 2 - Real Storage Activity (Per Processor)
DESCRIPTION - Utilization of real memory on a processor basis.
This record is needed because free storage requests
are not expected to be evenly distributed across all
processors in a complex. A separate record is
generated for each online processor.
