DSECT NAME - SYTSHS FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRSYTSHS DESCRIPTIVE NAME - Monitor Sample Record Domain 0 - System Domain Record 7 - Shared Storage Data DESCRIPTION - Named Saved System(NSS), Discontiguous saved segment(DCSS) and Shared Address Spaces management. Virtual disk in storage information is also included in this record since the disk is supported by storage, not DASD.
