DSECT NAME - SYTCUG FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRSYTCUG DESCRIPTIVE NAME - Monitor Sample Record Domain 0 - System Domain Record 15 - Logical CPU Utilization Data (Global) DESCRIPTION - Global description of logical CPU utilization in a LPAR environment. This record contains only data of global nature and exists only when the system is running under control of the PR/SM feature. For descriptions of individual logical partitions and their logical CPUs, see the MRSYTCUP (Domain 0, Record 16) record.
