System Administration Commands poolstat(1M)
NAME
poolstat - report active pool statistics
SYNOPSIS
poolstat [-p pool-list] [-r rset-list] [-T u | d ] [interval [count]]
poolstat [-p pool-list] [-o format -r rset-list]
[-T u | d ] [interval [count]]
DESCRIPTION
The poolstat utility iteratively examines all active pools
on the system. It reports statistics based on the selectedoutput mode. poolstat provides options to examine only
specified pools and report resource set-specific statistics.
Without options, poolstat examines all pools, reports basic
statistics for their resource sets, and exits. DISPLAY FORMATSIn default output format, poolstat outputs a header line and
a line for each pool. The line begins with the pool ID and its name, followed by a column of statistical data for the processor set attached to the pool. The columns are defined as follows: id Pool ID. pool Pool name. rid Resource set id. rset Resource set name. type Resource set type. min Minimum resource set size. max Maximum resource set size.SunOS 5.11 Last change: 16 Jun 2009 1

size Current resource set size. used The measure of how much of the resource set iscurrently is use. This is calculated as the percen-
tage utilization of the resource set multiplied byits size. If resource set has been reconfigured dur-
ing last sampling interval, this value might be notreported (-).
load The absolute representation of the load that is puton the resource set. For the definition of this pro-
perty see libpool(3LIB). OPTIONS The following options are supported:-o format Report statistics according to the format
specification given in format. See DISPLAY FORMATS.The -o option accepts lists as arguments.
Items in a list can be either separated by commas or enclosed in quotes and separated by commas or spaces.You can specify multiple -o options. The
format specification is interpreted as the whitespace separated concatenation of all the format option arguments.The -o option must be used in conjunction
with the -r option.
-p pool-list Report only pools whose names are in the
given list. If the -r option is also used,
this option selects only resource sets whichbelong to pools in the given list. Statis-
tics for pools or resource sets are reported in the same order in which pool names arelisted on the pool-list. Pool can be speci-
fied by name or by ID.The -p option accepts lists as arguments.
Items in a pool-list can only be separated
by spaces.SunOS 5.11 Last change: 16 Jun 2009 2

-r rset-list Report resource set statistics. If the
rset-list argument is "all", then all possi-
ble resource set types are selected.The -r option accepts lists as arguments.
Items in a list can be either separated by commas or enclosed in quotes and separated by commas or spaces.The following resource set types are sup-
ported: all All resource set types pset Processor set-T u | d Display a time stamp.
Specify u for a printed representation of the internal representation of time. See time(2). Specify d for standard date format. See date(1). OPERANDS The following operands are supported: count The number of times that the statistics arerepeated. By default, poolstat reports statis-
tics only once. If neither interval nor count are specified, statistics are reported once. If interval is specified and count is not, statistics are reported indefinitely. interval The sampling interval in seconds. If neither interval nor count are specified, statistics are reported once. If interval is specified and count is not, statistics are reported indefinitely.EXAMPLES
Example 1 Using poolstat

System Administration Commands poolstat(1M)
The following example shows the default output from thepoolstat utility:
% poolstat
pset id pool size used load0 pool_default 4 3.6 6.2
1 pool_admin 4 3.3 8.4
Example 2 Reporting Resource Set Statistics The following example reports resource set statistics.% poolstat -r pset
id pool type rid rset min max size used load0 pool_default pset -1 pset_default 1 65K 2 1.2 8.3
1 pool_admin pset 1 pset_admin 1 1 1 0.4 5.2
2 pool_other pset -1 pset_default 1 65K 2 1.2 8.3
Resource sets attached to multiple pools, as pset_default in
the example above, are listed multiple times, once for each pool. Example 3 Restricting the Output to the List of Pools The following example restricts the output to the list of pools% poolstat -p pool_default
pset id pool size used load0 pool_default 8 5.3 10.3
% poolstat -p 'pool_admin pool_default'
pset id pool size used load1 pool_admin 6 4.3 5.3
0 pool_default 2 1.9 2.0
% poolstat -r all -p 'pool_admin pool_default'

Example 4 Customizing Output The following example customizes output:% poolstat -r -o pool,rset,size,load
