NAME
zonestat - report active zone statistics
SYNOPSIS
zonestat [-z zonelist] [-r reslist] [-n namelist] [-T u | d | i]
[-R reports] [-q] [-x] [-b brandlist] [-p [-P lines]]
[-S cols] interval [duration [report]]
DESCRIPTION
The zonestat utility reports on the CPU, memory, networking, and
resource control utilization of the currently running zones. Each
zone's utilization is reported both as a percentage of system resources
and the zone's configured limits.
The zonestat utility prints a series of interval reports at the speci‐
fied interval. It optionally also prints one or more summary reports at
a specified interval.
The default output is a summary of CPU, physical and virtual memory,
and networking utilization. The -r option can be used to choose
detailed output for specific resources.
Security
When run from within a non-global zone (NGZ), only psets visible to the
NGZ are reported. The NGZ output includes all of other system
resources, such as memory and limits.
For all reported resources, the per-NGZ use is reported. Use of each
resource by the system itself, i.e. that cannot be attributed to a par‐
ticular zone, is reported as [system].
Inside a solaris-kz brand zone, only that zone's resource use is visi‐
ble.
proc_info privilege is required to use the zonestat utility. This priv‐
ilege is a member of the basic privilege set.
OPTIONS
The following options are supported:
-n name[,name]
Specify a list of resource names on which to report. For pset
resources, this is the name of the pset. For physical-memory,
locked-memory, and virtual-memory resources, the only names are
mem_default and vm_default. For network resources, this is name of
a datalink.
Dedicated-cpu psets can be specified by their dedicated-cpu pset
name (SYSzone_<zonename>) or by just their zonename. Psets created
by psrset can be specified by their psrset pset name (SYSp‐
srset_<id>), or just by their pset id. See resource-management(7)
for more information on existing types of pools and psets.
For sysstats and fsstats, all resource names that belong to them
can be used as names. In this case, only columns specified by names
are printed. See example 7.
In addition to a comma-separated list, multiple -n options can be
specified to report on a set of resources.
-p
Parsable output.
Print output in stable, machine--parsable format. Individual fields
are delimited with a colon (:). The line format is:
report type:resource:field[:field]*
If the -T is specified, each line is prefixed with a timestamp:
The report types are: report-total, report-average, report-high,
and interval.
For the list of existing resource types, see the -r option.
On top of the resource types defined with the -r option, the header
resource is a special resource used to start the beginning of an
interval or a summary report. All output lines between header
resources belong to the same report. The header resource type can‐
not be used with the -r option.
The remaining fields are resource type specific and, save for
exceptions listed below, the ordering of the fields reflects the
ordering of columns in the default output for each resource type.
See the zonestat utility output for details.
For the summary resource, the remaining fields are as follows (see
the OUTPUT section below for the explanation of the column head‐
ings):
line type (see -P):USED CPU:%PART:%CAP:%SHRU:USED PhysMem:
%USED PhysMem:%CAP PhysMem:USED VirtMem:%USED VirtMem:
%CAP VirtMem:PBYTE:%PUSE:STLN:%STLN
For the network resource, the remaining fields are as follows, for
the default and extended (option -x) output, respectively:
<zone view>:zonename:RBYTE:OBYTE:TOBYTE:MAXBW:%MAXBW:
PRBYTE:%PRBYTE:POBYTE:%POBYTE
<link view>:linkname:zonename:RBYTE:OBYTE:TOBYTE:MAXBW:%MAXBW:
PRBYTE:%PRBYTE:POBYTE:%POBYTE
For the processor-set resource, the remaining fields are as fol‐
lows:
pset type:pset ID:line type (see -P):USED CPU:%USED CPU:CAP:%CAP:
SHRS:%SHR:%SHRU:USED CPU time [H]H-MM-SS.SS:STLN:%STLN
All existing output fields are stable. Future versions might intro‐
duce new report and resource types. Future versions might also add
additional new fields to the end of existing output lines.
Running in a global zone, the statistics provided for solaris-kz
brand zones are from the host point of view, and may differ from
those reported within the zone; see solaris-kz(7).
-P line[,line]
For parsable output, specify lines to output. One or more of the
following line types can be chosen:
header
Each interval and summary report has a header, which prints
details such as the interval timestamp, interval number, and
the seconds count. If the header line is chosen, each interval
is also finalized with a footer.
resource
The lines specifying each resource limit, if applicable. For
example, there are no limits specified for resources sysstats
and fsstats.
system
The utilization of each resource by the system. This includes
the kernel, and any resource consumption not contributed to a
specific zone. When zonestat is run from within a non-global-
zone, this value is the aggregate resource consumed by the sys‐
tem and all other zones. system utilization for network
resource type is not supported.
total
The total utilization of each resource.
zones
Lines detailing the per-zone utilization of each resource.
By default, all lines are present in the parsable output.
-q
Quiet mode. Only print summary reports (requires the -R option).
All interval reports are omitted.
-r resource[,resource]
Specify resource types on which to report. The available resources
are: physical-memory, virtual-memory, locked-memory, processor-set,
processes, lwps, shm-memory, shm-ids, sem-ids, msg-ids, lofi, net‐
work, sysstats, and fsstats.
In particular, sysstats shows number of total syscall, forks,
vforks, fork-fails, exec, semops, while fsstats shows number of
read calls, write calls, bytes read by rdwr(), bytes written by
rdwr(), and the number of pathname lookups.
Additional resource names are available to provide some common
resource output combinations:
summary A summary of CPU, physical-memory, virtual-memory,
and network usage is printed.
memory An alias for "physical-memory,virtual-mem‐
ory,locked-memory".
psets Same as processor-set.
default-pset The default pset only is reported.
limits An alias for "processes,lwps,lofi".
sysv An alias for "shm-memory,shm-ids,sem-ids,msg-ids".
all All resource types.
By default the summary resource is printed.
In addition to a comma-separated list, multiple -r options can be
specified to report on a set of resources types.
The system's CPUs can be partitioned into psets. By default, all
CPUs are in a single pset named pset_default.
Memory is not partition-able into sets. The zonestat utility output
for these resources shows them as named mem_default and vm_default.
The all resource specifies that all resource types should be
reported.
-b brand[,brand]
Display only the brand(s) specified by this option.
-R report[,report]
Print a summary report. The supported report types are described
below. In addition to a comma-separated list, multiple -R options
can be specified for a set of summary reports.
total
Prints a summary report detailing the following for each
resource:
psets
Total CPU used since start of command invocation. The per‐
cent used for each zone includes time that a zone was not
running. For instance, if a zone used 100% of the CPU while
it was running, but the zone was halted for half of the
intervals, then the summary report shows the zone used 50%
of the CPU time.
memory, limits, sysv
Average resource used of all intervals reported since com‐
mand invocation. This average factors in intervals in which
a zone was not running. For example if a zone used on aver‐
age of 100M of physical memory while it was running, and
was only running for half the intervals, then the summary
report shows that the zone used 50M of physical memory on
average.
network
Sum of all bytes that are transmitted and received by all
datalink utilizing physical bandwidth. The sum is calcu‐
lated since start of command invocation and is normalized
to number of bytes per second. The percentage used is based
on total available bandwidth.
sysstats, fsstats
Sum of resources used by all CPUs visible to the zone.
average
Similar to total, but only intervals in which a zone is running
are factored in. For example, if a zone was only running for a
single interval, and during that interval, the zone used 200M
of virtual memory, then it's average virtual-memory is 200M,
regardless of the number of intervals reported before the sum‐
mary report.
high
Print a summary report detailing the highest usage of each
resource and zone during any interval of the zonestat utility
invocation.
-S col[,col]
Sort zones utilizing each resource.
The following sorting columns can be specified:
name
Sort alpha-numerically by zone name.
used
Sort by quantity of resource used. For networking resource,
this is same as sort by bytes.
This is the default.
cap
Sort by configured cap.
pcap
Sort by percent of cap used.
shr
Sort by allocated share.
pshru
Sort by percent of share used.
bytes
Sort networking by total bytes transmitted and received.
prbyte
Sort networking by percentage of received bytes over the wire.
pobyte
Sort networking by percentage of transmitted bytes over the
wire.
maxbw
Sort networking by percentage of bandwidth used.
cpu
Sort by CPU usage in the summary output. This is the default.
physical-memory
Sort by physical memory usage in the summary output.
virtual-memory
Sort by virtual memory usage in the summary output.
network
Sort by network usage in the summary output.
exec, fork, fork-fail, name-lookup, read, readbyte, sema, syscall,
vfork, write, writebyte
Sort by quantity of corresponding resources used.
-T u | d | i
Include timestamp of each report. The following formats are sup‐
ported:
d Standard date format. See date(1). This option is not valid
with -p.
i Time formatted as the ISO 8601 compliant format:
YYYYMMDDThhmmssZ
u A printed representation of the internal representation of
time. See time(2). This is also known as unix time.
-x
Display an extended view with more detailed information. For exam‐
ple, when used with network resource, the extended view list
details of each virtual datalink.
-z zonename[,zonename]
Specify a list of zones on which to report. By default all zones
are reported.
In addition to a comma-separated list, multiple -z options can be
specified to report on a set of zones. The output includes any
resources which have usage by the specified zones.
OPERANDS
The following operands are supported:
interval
Specifies the length in seconds to pause between each interval
report. An interval of default uses the configured interval of the
zones monitoring service. See zonestatd(8).
interval is required. An interval of zero is not permitted. inter‐
val can be specified as [nh][nm][ns], such as 10s or 1m.
duration
Specifies the number of intervals to report. Defaults to infinity
if not specified. The command duration is (interval * duration). A
duration of zero is invalid. A value of inf can also be specified
to explicitly choose infinity.
Duration can also be specified as [nh][nm][ns]. In this case, dura‐
tion is interpreted as the duration of execution time. The actual
duration is rounded up to the nearest multiple of the interval.
report
Specify the summary report period. For instance, a report of 4 pro‐
duces reports every 4 intervals. If the command duration is not a
multiple of report, then the last report is of any remaining inter‐
vals.
report can also be specified as [nh][nm][ns]. In this case, reports
are output at the specified time period, rounded up to the nearest
interval. If the command duration is not a multiple of report, then
the last report is of any remaining intervals.
Requires -R. If -R is specified and report is not, the report
period is the entire command duration, producing the specified
reports at the end of execution.
OUTPUT
The following list defines the column heading of the command output:
SYSTEM-MEMORY
The total amount of memory available on the physical host.
SYSTEM-LIMIT
The maximum amount of resource available on the physical host.
CPUS
The number of CPUs allocated to a pset
ONLINE
Of the CPUs allocated to a pset, the number of CPUs which can exe‐
cute processes.
MIN/MAX
The minimum and maximum number of CPUs which can be allocated to
the pset by the system.
ZONE
The zone using the resource. In addition to zone names, this column
can also contain:
[total] The total quantity of resource used system-wide.
[system] The quantity of resource used by the kernel or in a
manner not associated with any particular zone.
When zonestat is used within a non-global zone, [sys‐
tem] designates the aggregate resource used by the sys‐
tem and by all other zones.
For network resources, system usage of network is not
available.
USED
The amount of resource used.
%USED
The amount of resource used as a percent of the total resource.
STLN
The amount of CPU time stolen from the zone. The Stolen Time is
supported only by some zone brands. The value of Stolen Time
reflects the time when the zone could not run due to the host using
CPU resources for other purposes. For more information about Stolen
Time refer to solaris-kz(7).
For the [system] row Stolen Time of the current system is reported.
For the [total] row sum of Stolen Time of the current system and
all the zones in the system is reported.
%STLN
The amount of CPU time stolen as a percent of the total CPU time
available.
%PART
The amount of CPU used as a percentage of the total CPU in a pro‐
cessor-set to which the zone is bound. A zone can only have pro‐
cesses bound to multiple psets if it is the global zone, or if
psrset(8) psets are used. If multiple binding are found for a zone,
its %PART is the fraction used of all bound psets. For [total] and
[system], %PART is the percent used of all CPUs on the system.
CAP
If a zone is configured to have a cap on the given resource, the
cap is displayed in this column.
%CAP
The amount of resource used as a percent of zone's configured cap.
SHRS
The number of shares allocated to the zone. For the [total] row,
this is the total number of shares allocated to all zones sharing
the resource. If a zone is not configured to use shares, and is
sharing a resource with other zones that are configured to use
shares, this column contains no-fss for the zone.
%SHRS
The fraction of the total shares allocated to the zone. For
instance, if 2 zones share a pset, each with 10 shares, then each
zone has a %SHR of 50%.
%SHRU
Of the share allocated to the zone, the actual used resource as the
fraction of resource 100%. Because shares are only enforced when
there is resource contention, it is possible for a zone to have a
%SHRU in excess of 100%.
TOBYTE
The total number of bytes transmitted and received by datalinks or
virtual links.
PRBYTE
The number of received bytes that consumes physical bandwidth.
RBYTE
The number of received bytes.
POBYTE
The number of transmitted bytes that consumes physical bandwidth.
OBYTE
The number of transmitted bytes.
%PRBYTE
The percentage of available physical bandwidth used to receive
PRBYTE.
%POBYTE
The percentage of available physical bandwidth used to transmit
POBYTE.
PBYTE
The sum of PRBYTE and POBYTE.
%PUSE
PBYTE as a percent of the total available physical bandwidth.
LINK
The name of a datalink.
MAXBW
The maximum bandwidth configured on a datalink.
%MAXBW
The sum of all transmitted and received bytes as a percentage of
configured maximum bandwidth.
exec, fork, fork-fail, name-lookup, read, readbyte, sema, syscall,
vfork, write, writebyte
The amount of resources used by each resource name.

NOTES
The zonestat utility depends on the zones monitoring service: svc/sys‐
tem/zonestat:default. If the zonestat service is stopped while the zon‐
estat utility is running, the zonestat command invocation quits without
printing additional reports. The reports (-R) is printed if zonestat is
interrupted (by CTRL/c, SIGINT) before reaching the next report period.
