Measure Reference Manual

ENDING-EOF
EOF value of the file, in bytes, at measurement stop time or measurement interval copy time. The
REPORT RATE value does not affect the display of this value in MEASCOM. This item is displayed
in its absolute value in bytes, followed by the ratio of ENDING-EOF over STARTING-EOF.
Counter type: Snapshot.
ENDING-ROWS
Number of rows in the SQL table at the end of a measurement interval. This counter is valid only
if the table had zero rows at some time since the file open.
Counter type: Snapshot.
EXTENT-ALLOCATIONS
Number of times a file extent is allocated.
Counter type: Incrementing.
LOCK-BOUNCES
Number of bounced locks (FELOCKED = error 73) returned to the file system. For SQL tables, a
bounced lock is a result of the CONTROL TABLE command with the RETURN-IF-LOCKED control
option. For Enscribe files, a bounced lock is a result of the SETMODE 4 function with Param.<15>
= 1 (alternate lock mode).
Counter type: Incrementing.
LOCK-TIMEOUTS
Number of timeouts on locks (error 40). When a timeout value for a request expires, the file system
(Enscribe and SQL/MP) sends a cancel request to the disk process. If the disk process finds the
request still waiting for lock to be granted, the request is dequeued from the lockwait queue, and
this counter is advanced.
Counter type: Incrementing.
LOCKWAIT-TIME
Time spent waiting for locks.
The REQUESTS-BLOCKED counter counts the number of blocked requests—that is, the number of
times requests are queued to locks. When the REPORT RATE value is on, this counter returns the
average wait time (LOCKWAIT-TIME divided by REQUESTS-BLOCKED).
Counter type: Lockwait.
MAX-LOCKWAIT-TIME
Maximum wait time for each lock. Use this number as a guide to set the timeout value in the
application. REPORT RATE ON has no effect on this counter value.
Counter type: Max value.
OPEN-QTIME
Time for all the opens of this file (including transient opens).
Counter type: Queue.
OSS-BLOCK-WRITE-BYTES
Number of bytes written by DP2 as a result of OSS-BLOCK-WRITES.
Counter type: Accumulating.
