poolstat(1M) System Administration Commands poolstat(1M)NAMEpoolstat - report active pool statistics
SYNOPSISpoolstat [-p pool-list] [-r rset-list] [interval [count]]
poolstat [-p pool-list] [-o format -r rset-list] [interval [count]]
DESCRIPTION
The poolstat utility iteratively examines all active pools on the sys‐
tem. It reports statistics based on the selected output 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 FORMATS
In 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.
size Current resource set size.
used The measure of how much of the resource set is cur‐
rently is use. This is calculated as the percentage
utilization of the resource set multiplied by its size.
If resource set has been reconfigured during last sam‐
pling interval, this value might be not reported (-).
load The absolute representation of the load that is put on
the resource set. For the definition of this property
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 speci‐
fication 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 which belong to pools in the given list.
Statistics for pools or resource sets are reported in
the same order in which pool names are listed on the
pool-list. Pool can be specified by name or by ID.
The -p option accepts lists as arguments. Items in a
pool-list can only be separated by spaces.
-r rset-list Report resource set statistics. If the rset-list argu‐
ment is "all", then all possible 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 supported:
all All resource set types
pset Processor set
OPERANDS
The following operands are supported:
count The number of times that the statistics are
repeated. 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
The following example shows the default output from the poolstat util‐
ity:
% poolstat
pset
id pool size used load
0 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 load
0 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 exam‐
ple 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 load
0 pool_default 8 5.3 10.3
% poolstat-p 'pool_admin pool_default'
pset
id pool size used load
1 pool_admin 6 4.3 5.3
0 pool_default 2 1.9 2.0
% poolstat-r all -p 'pool_admin pool_default'
id pool type rid rset min max size used load
1 pool_admin pset 1 pset_admin 1 1 1 0.9 2.3
2 pool_default pset -1 pset_default 1 65K 2 2.0 2.0
Example 4: Customizing Output
The following example customizes output:
% poolstat-r -o pool,rset,size,load
pool rset size load
pool_default pset_default 4 4.5
pool_admin pset_admin 4 2.1
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
2 Invalid command line options were specified.
