DSECT NAME - SYTXSP
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRSYTXSP
DESCRIPTIVE NAME - Monitor Sample Record
Domain 0 - System Domain
Record 5 - Expanded Storage Data (per processor)
DESCRIPTION - Assesses use and benefits derived from expanded
storage. A separate record is generated for each
online processor. This information should be used
with record MRSYTXSG (Domain 0, Record 14) for a
complete picture of expanded storage use.
