Measure Reference Manual

ABS-SEGS-START
Number of items on the queue described by ABS-SEGS-QTIME at the start of the measurement
interval.
Counter type: Snapshot.
ACCEL-BUSY-TIME
Time that the CPU was busy executing accelerated code in this process. This counter applies only
to measurements taken on a TNS/R or TNS/E system.
See Usage Notes for H-Series and J-Series PROCESS Entities (page 310).
Counter type: Busy.
ALLOC-SEG-CALLS
Number of successful calls made to the SEGMENT_ALLOCATE_ or ALLOCATESEGMENT procedures.
Counter type: Incrementing.
BEGIN-TRANS
Number of times the process began a TMF transaction.
Counter type: Incrementing.
CHECKPOINTS
Number of calls to the CHECKPOINT procedure. This counter includes both user and system calls
to this procedure.
Many system processes do their own checking rather than calling the CHECKPOINT procedure.
These processes do not increment this counter.
Counter type: Incrementing.
COMP-TRAPS
Number of times a compatibility trap occurred during execution of this process. A compatibility
trap is a data misalignment event, an unexpected transition to or from accelerated or unaccelerated
code, or a relative segment 2 or 3 problem. See the EPTRACE Manual for further details.
Counter type: Incrementing.
CPU-BUSY-TIME
Time that the CPU spent executing the measured process:
• In D-series RVUs, this counter is not advanced for the sending process when LDONE queuing
is in use.
• For measurements on systems running G05 and later RVUs, this counter includes any
page-defaulting activity performed on behalf of this process.
• For pre-G05.00 G-series RVUs, all page-faulting is charged to the memory manager process
$VIRTUAL.
For TNS/R systems, CPU-BUSY-TIME is the sum of ACCEL-BUSY-TIME, TNS-BUSY-TIME, and
TNSR-BUSY-TIME.
For TNS/E systems, CPU-BUSY-TIME is the sum of ACCEL-BUSY-TIME, TNS-BUSY-TIME, and
NATIVE-BUSY-TIME. A CPU-BUSY-TIME value is always displayed. However, the ACCEL-BUSY-TIME,
TNS-BUSY-TIME, and NATIVE-BUSY-TIME counter values are only calculated and displayed if a
PROCESSH measurement was active during the measurement. For details about the behavior of
the ACCEL-BUSY-TIME, TNS-BUSY-TIME, and NATIVE-BUSY-TIME counters, see the descriptions of
these counters.
