sar(1M) sar(1M)

%swpocc The percentage of time the swap queue of runnable processes (processes

swapped out but ready to run) was occupied.

-v Report status of text, process, inode and ﬁle tables:

text-sz (Not Applicable);

proc-sz The current-size and maximum-size of the process table;

inod-sz The current-size and maximum-size of the inode table (inode cache);

file-sz The current-size and maximum-size of the system ﬁle table;

text-ov (Not Applicable);

proc-ov The number of times the process table overﬂowed (number of times the

kernel could not ﬁnd any available process table entries) between sample

points;

inod-ov The number of times the inode table (inode cache) overﬂowed (number of

times the kernel could not ﬁnd any available inode table entries) between

sample points;

file-ov The number of times the system ﬁle table overﬂowed (number of times the

kernel could not ﬁnd any available ﬁle table entries) between sample

points.

-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.

-A Report all data. Equivalent to -udqbwcayvm .

-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.

EXAMPLES

Watch CPU activity evolve for 5 seconds:

sar 1 5

Watch CPU activity evolve for 10 minutes and save data:

sar -o temp 60 10

Review disk and tape activity from that period later:

sar -d -f temp

Review cpu utilization on a multi-processor system later:

sar -u -M -f temp

WARNINGS

Users of sar must not rely on the exact ﬁeld widths and spacing of its output, as these will vary depend-

ing on the system, the release of HP-UX, and the data to be displayed.
