Measure Reference Manual

CONTROL-POINT-WRITES
Number of dirty cache blocks that the disk process wrote to disk at TMF control points. For a
discussion of TMF auditing, see the TMF Operations and Recovery Guide.
Counter type: Incrementing.
CONTROL-POINTS
Number of times the disk process wrote a TMF control point record to its audit-trail file. For a
discussion of TMF auditing, see the TMF Operations and Recovery Guide.
Counter type: Incrementing.
DBIO-READS
Number of read operations to the measured device that were enabled for direct bulk I/O to a
requesting application processor. This counter is a subset of READS.
Counter type: Incrementing.
DBIO-WRITES
Number of write operations to the measured device that were enabled for direct bulk I/O from a
requesting application processor. This counter is a subset of WRITES.
Counter type: Incrementing.
DEFERRED-QTIME
Time (in microseconds) that requests subject to deferral actually spent deferred. This counter is a
subset of DEFREQ-QTIME.
Counter type: Queue.
DEFREQ-QTIME
Time (in microseconds) that requests subject to deferral spent on the disk process internal queue
(including any current active or deferred requests). This counter is a subset of REQUEST-QTIME.
Counter type: Queue.
DEFREQS
Number of requests received by the disk process that are subject to deferral. This counter is a
subset of REQUESTS.
Counter type: Incrementing.
DEVICE-QBUSY-TIME
Time spent in a state in which requests of any number or type were queued to this disk in this
processor.
Because of concurrent activity in the write and read queues, WRITE-QBUSY-TIME plus
READ-QBUSY-TIME does not equal DEVICE-QBUSY-TIME. For more information, see Usage Notes
for G-Series DISC Entities (page 206).
Counter type: Queue Busy.
ENDING-FREE-BLOCKS
Number of free blocks on the volume at the time indicated by the TO time. The counter is updated
only for the primary path record. The RATE attribute has no effect on how this counter is displayed.
The primary path can be obtained from the LIST DISC command (Measure H03 and later PVUs)
or the SCF INFO DISCNAME, DETAIL command.
Counter type: Snapshot.
