Measure Reference Manual

NOTE: The CPU-BUSY-TIME counter is enhanced for more precise measurement of processor
utilization. Measurements on systems running D-series and G-series RVUs might show slightly higher
utilization than comparable measurements on systems running C-series RVUs. The difference appears
mainly on systems that run at low utilization levels.
PageDescriptionRelated Counter
166Similar, but is the busy time for the entire processor.CPU CPU-BUSY-TIME
Identifies the CPU executing the processPROCESS CPU-NUM
Counter type: Busy.
CURRENT-PRIORITY-END
(ZMS Style only) In H06.25/J06.14 and later RVUs, the current execution process priority at the
end of the measurement interval. See also Usage Notes for H-Series and J-Series PROCESS Entities
(page 310).
Counter type: Snapshot.
CURRENT-PRIORITY-START
(ZMS Style only) In H06.25/J06.14 and later RVUs, the current execution priority at the start of
the measurement interval. See also Usage Notes for H-Series and J-Series PROCESS Entities
(page 310).
Counter type: Snapshot.
DISPATCHES
Number of times the process was selected from the ready list and executed by the CPU identified
by the CPU-NUM field. You can expect one dispatch for each I/O operation, plus additional
dispatches caused by the process being preempted by higher priority processes.
Counter type: Incrementing.
EXT-SEGS-QTIME
Time that extended segments were allocated to the process through the SEGMENT_ALLOCATE_
procedure. This counter includes both user and system calls to this procedure.
The system does not use SEGMENT_ALLOCATE_ when allocating segments for process code and
data stack segments.
Counter type: Queue.
FILE-OPEN-CALLS
Number of calls to the FILE_OPEN_ or OPEN procedures. Counts all opens including opens of
regular files, pipes, FIFOs, AF_INET sockets, AF_UNIX sockets, directories, /dev/null, and TTYs.
Includes implicit opens due to the fork(),exec*() family of process creation APIs.
Counter type: Incrementing.
INFO-CALLS
Number of calls to these procedures that resulted in a message being sent to a process (IOP or
other) to obtain the information requested:
getsockopt()DEVICEINFO2FILEINFO
pathconf()access()FILERECINFO
PROCESS 301
