NAME
kstat - obsolete display kernel statistics
SYNOPSIS
kstat [-lpq] [-T u | d ] [-c class] [-m module]
[-i instance] [-n name] [-s statistic]
[interval [count]]
kstat [-lpq] [-T u | d ] [-c class]
[module:instance:name:statistic]...
[interval [count]]
DESCRIPTION
The kstat utility examines the available kernel statistics, or kstats,
on the system and reports those statistics which match the criteria
specified on the command line. Each matching statistic is printed with
its module, instance, and name fields, as well as its actual value.
Kernel statistics may be published by various kernel subsystems, such
as drivers or loadable modules; each kstat has a module field that de‐
notes its publisher. Since each module might have countable entities
(such as multiple disks associated with the sd(4D) driver) for which it
wishes to report statistics, the kstat also has an instance field to
index the statistics for each entity; kstat instances are numbered
starting from zero. Finally, the kstat is given a name unique within
its module.
Each kstat may be a special kstat type, an array of name-value pairs,
or raw data. In the name-value case, each reported value is given a la‐
bel, which we refer to as the statistic. Known raw and special kstats
are given statistic labels for each of their values by kstat; thus, all
published values can be referenced as module:instance:name:statistic.
When invoked without any module operands or options, kstat will match
all defined statistics on the system. Example invocations are provided
below. All times are displayed as fractional seconds since system boot.
OPTIONS
The tests specified by the following options are logically ANDed, and
all matching kstats will be selected. A regular expression containing
shell metacharacters must be protected from the shell by enclosing it
with the appropriate quotes.
The argument for the -c, -i, -m, -n, and -s options may be specified as
a shell glob pattern, or a Perl regular expression enclosed in '/'
characters.
-c class Displays only kstats that match the specified class.
class is a kernel-defined string which classifies the
"type" of the kstat.
-i instance Displays only kstats that match the specified instance.
-l Lists matching kstat names without displaying values.
-m module Displays only kstats that match the specified module.
-n name Displays only kstats that match the specified name.
-p Displays output in parseable format. All example output
in this document is given in this format. If this op‐
tion is not specified, kstat produces output in a hu‐
man-readable, table format.
-q Displays no output, but return appropriate exit status
for matches against given criteria.
-s statistic Displays only kstats that match the specified statis‐
tic.
-T d | u Displays a time stamp before each statistics block, ei‐
ther in date(1) format (d) or as an alphanumeric repre‐
sentation of the value returned by time(2) (u).
OPERANDS
The following operands are supported:
module:instance:name:statistic
Alternate method of specifying module, instance, name, and statis‐
tic as described above. Each of the module, instance, name, or sta‐
tistic specifiers may be a shell glob pattern or a Perl regular ex‐
pression enclosed by '/' characters. It is possible to use both
specifier types within a single operand. Leaving a specifier empty
is equivalent to using the '*' glob pattern for that specifier.
interval
The number of seconds between reports.
count
The number of reports to be printed.
EXAMPLES
In the following examples, all the command lines in a block produce the
same output, as shown immediately below. The exact statistics and val‐
ues will of course vary from machine to machine.

NOTES
If the pattern argument contains glob or Perl RE metacharacters which
are also shell metacharacters, it will be necessary to enclose the pat‐
tern with appropriate shell quotes.
The use of this command is deprecated. It may be removed in a future
release of Oracle Solaris. Use of kstat2 command is recommended. For
more information, see the kstat2(8) man page.
