%busy Portion of time lunpath was busy servicing a request.
avque Average number of requests outstanding for the lunpath.
r/s Number of reads per second from the lunpath.
w/s Number of writes per second to the lunpath.
blks/s Number of bytes transferred (in 512-byte units) from and to the LUN using
this lunpath.
avwait Average time (in milliseconds) that transfer requests waited idly on queue for
this lunpath.
avserv Average time (in milliseconds) to service each transfer request (includes seek,
rotational latency, and data transfer times) for this lunpath.
-m Report message and semaphore activities:
msg/s Number of System V msgrcv() calls per second.
sema/s Number of System V semop() calls per second.
select/s Number of System V select() calls per second. This value will only be
reported if the -S option is also explicitly specified.
-M Report the per-processor data on a multi-processor system when used with
-q and/or -u
options. If the -M option is not used on a multi-processor system, the output format of the
-u and -q options is the same as the uni-processor output format and the data reported is
the average value of all the active processors.
-o Saves the samples in binary format.
-p Report the specified ProcessorSet (pset) information. This option should be used with the
-u
or -q option.
-P Report ProcessorSet (pset) information, mapping to the processor in the system or the
specified pset. This option can only be used with -M and -q,or-M
and -u options. It can
also be combined with
-p option to display information for a particular pset. If system is not
pset configured, it will display a warning message.
-q Report average queue length while occupied, and percent of time occupied. On a multi-
processor machine, if the -M option is used together with the -q option, the per-CPU run
queue as well as the average run queue of all the active processors are reported. If the
-M
option is not used, only the average run queue information of all the active processors is
reported. In a multi-processor pset configured system, if the
-M option is used with the -P
option, then the pset column will be displayed before the cpu column:
pset pset id (only on a multi-processor and pset configured system, used with
-P,
-M, and -q option).
cpu cpu number (only on a multi-processor system and used with the -M option).
runq-sz Average length of the run queue(s) of processes (in memory and runnable).
%runocc The percentage of time the run queue(s) were occupied by processes (in
memory and runnable).
swpq-sz Average length of the swap queue of runnable processes (processes swapped
out but ready to run). This column will not be displayed when -p option is
used to display a particular ProcessorSet (pset) information in a pset
configured system.
%swpocc The percentage of time the swap queue of runnable processes (processes
swapped out but ready to run) was occupied. This column will not be
displayed when -p option is used to display a particular ProcessorSet (pset)
information in a pset configured system.
-R This option is used with the -d option to report the number of reads and writes per second to
the device. Refer to the description of the -d option for details.
-S Report the number of System V select() calls per second. This option is valid only if the
-m option is specified.
