DSECT NAME - IODQEQ
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRIODQEQ
DESCRIPTIVE NAME - Monitor Sample Record
Domain 6 - I/O Domain
Record 55 - Host EQDIO Queue-based data
DESCRIPTION - Describes I/O per-queue data for host EQDIO shadow
queues where quest EQDIO instructions are simulated.
NOTES: This record is collected for host shadow queues.
The IODQDE_QueueData section will contain an entry
for each queue defined for this real device.
Each entry is identified by the IODQEQ_QI1QID.
