Measure Reference Manual

SUBDEVICE
Subdevice identifier for a particular SCSI device on a multifunction I/O board (MFIOB):
Device typeIdentifier
ServerNet bus interface (SBI)0
Internal SCSI Controller #11
Internal SCSI Controller #22
COMM and SP3
SP to SP communications4
External SCSI port controller5
For IPC records, SUBDEVICE applies to the destination (listener) processor. For more information,
see Usage Notes for SERVERNET Entities (page 332).
Common and ZMS Style Only Counter Field DDL Definitions for SERVERNET Entities
These counter fields are used in both styles of DDL records. Fields that are used in ZMS Style DDL
records only are noted.
Fields are listed alphabetically.
ACKS
Number of explicit acknowledgment messages sent. This counter applies only to IPC and RIPC
records.
Counter type: Incrementing.
IO-QBUSY-TIME
Time spent in a state in which requests of any number or type were queued for this entity.
Counter type: Queue Busy.
IO-QTIME
Time the SAC is busy performing I/Os.
With REPORT RATE ON, this is the average number of outstanding I/Os queued to this controller.
If the average number of I/Os is less than 1, the number can be interpreted as the controller busy
percentage.
Counter type: Queue.
READ-BYTES
Total number of bytes transferred as a result of read requests or pull operations and the bytes
received in pre-push operations from the linker CPU.
Counter type: Accumulating.
READ-CBYTES
For IPC and RIPC node classes, total number of message system protocol control bytes transferred
to this processor as a result of requests. For a CLIM node class, the total number of bytes in the
incoming control requests from the CLIM into the CPU. In all cases, these control bytes are not
included in the counter READ-BYTES.
Counter type: Accumulating.
