zonestat(1) -- report active zone statistics.
zonestat [-z zonelist] [-r reslist] [-n namelist] [-T u | d | i] [-R reports] [-q] [-p [-P lines]] [-S cols] interval [duration [report]]
The zonestat utility reports on the cpu, memory, 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 specified 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 utilization. The -r option can be used to choose detailed output for specific resources.
When run from within a non-global zone (NGZ), only processor sets visible to the NGZ are reported. The NGZ output will include all of other system resources, such as memory and limits.
For all reported resources, the NGZ's usage will be outputted. Usage of each resource by the system, global zone, and all other zones, will be reported as used by [system].
The following options are supported:
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 will include any resources which have usage by the specified zone(s).
Specify resource types on which to report. The available resources are: physical-memory, virtual-memory, locked-memory, processor-sets, processes, lwps, shm-memory, shm-ids, sem-ids, msg-ids, lofi The following nicknames can also be specified as resource names: summary: A summary of cpu, physical-memory, and virtual memory usage. memory: physical-memory, virtual-memory, and locked memory. psets: processor-sets default-pset The default pset only. limits: processes, lwps, lofi sysv: 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 processor sets (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 will show them as named "mem_default" and "vm_default". The "all" resource specifies that all resource types should be reported.
Specify a list resource names on which to report. For pset resources, this is the name of the processor set. For physical-memory, locked-memory, and virtual-memory resources, the only names are "mem_default" and "vm_default". Dedicated-cpu processor sets can be specified by their pset name ("SUNWtmp_<zonename>"), or by just their zonename. Processor sets created by psrset can be specified by their pool pset name "(SUNWlegacy_<psetid>)", or just by their psetid. In addition to a comma-separated list, multiple -n options can be specified to report on a set of resources.
-T u | d | i
Include timestamp of each report. The following formats are supported: u A printed representation of the internal representation of time. See time(2). This is also known as unix time. d Standard date format. See date(1). This option is not valid with -p. i Time formatted as the ISO 8601 compliant format: YYYYMMDDThhmmssZ
Print a summary report. The supported report types are described below. In addition to a comma-separated list, multiple -R's may 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 percent 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 will show the zone used 50% of the cpu time. memory, limits, sysv Average resource used of all intervals reported since command invocation. This average factors in intervals in which a zone was not running. For example if a zone used on average of 100M of physical memory while it was running, and was only running for half the intervals, then the summary report will show that the zone used 50M of physical memory on average. 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 will be 200M, regardless of the number of intervals reported before the summary report. high Print a summary report detailing the highest usage of each resource and zone during any interval of the zonestat utility invocation.
Sort zones utilizing each resource. The following sorting columns can be specified. name Sort alphanumerically by zone name. used Sort by quantity of resource used. cap Sort by configured cap. pcap Sort by percent of cap used. shr Sort by allocated share. pshru Sort by percent of share used. By default, output is sorted by quantity of resource used.
-q Quiet mode.
Only print summary reports (requires -R). All interval reports are omitted.
-p Parseable output.
Print output in stable, machine--parseable format. Individual fields will be delimited with ":". The line format is: <report type>:<resource>:<field>[:<field>]* If -T is specified each line is prefixed with a timestamp: <timestamp>:<report type>:<resource>:<field>[:<field>]* The report types are: report-total, report-average, report-high, interval The resource types are: header, footer, summary, physical-memory, virtual-memory, locked-memory, processor-set, processes, lwps, sysv-shared-memory, sysv-shmids, sysv-semids, sysv-msgids, lofi The "header" resource is a special resource used to state the beginning of an interval or summary report. All output lines between header resources belong to the same report. Each header has a matching footer. The remaining fields are resource type specific. See the zonestat utility output for details. All existing output fields are stable. Future versions may introduce new report and resource types. Future versions may also add additional new fields to the end of existing output lines.
For parseable output, specify lines to output in parseable output. One or more of the following line types can be chosen: resource The lines describing each resource. total The total utilization of each resource. system The utilization of each resource by the system. This includes the kernel, and any resource consumption not contributable to a specific zone. When zonestat is run from within a non-global-zone, this value will be the aggregate resource consumed by the system and all other zones. zones Lines detailing the per-zone utilization of each resource. header, footer For each interval, and summary report has a header, which prints details such as the interval and count information. After each report, and footer is also printed
Specifies the length in seconds to pause between each interval report. An interval of "default" will use the configured interval of the zones monitoring service (see zonestatd(1M). Interval is required. An interval of zero is not permitted. The interval can be specified as [nh][nm][ns], such as 10s or 1m.
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, duration will be interpreted as the duration of execution time. The actual duration will be rounded up to the nearest multiple of the interval.
report Specify the summary report period. For instance, a report of 4 would produce reports every 4 intervals. If the command duration is not a multiple of report, then the last report will be of any remaining intervals.
Report can also be specified as [nh][nm][ns]. In this case, reports will be outputted 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 will be of any remaining intervals. Requires -R. If -R is specified and report is not, the report period will be the entire command duration, producing the specified reports at the end of execution.
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 processor set. ONLINE Of the cpus allocated to a processor set, the number of cpus which can execute processes. MIN/MAX The minimum and maximum number of cpus which may be allocated to the processor set by the system. ZONE The zone using the resource. In addition to zone names, this column may 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, [system] designates the aggregate resource used by the system and by all other zones. USED The amount of resource used. PCT The amount of resource used as a percent of the total resource. %PART The amount of cpu uses as a percentage of the total cpu in a processor-set to which the zone is bound. A zone can only have processes bound to multiple processor sets if it is the global zone, or if psrset(1M) psets are used. If multiple binding are found for a zone, it's %PART will be 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 will be 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 will be 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 will contain "no-fss" for the zone. %SHR The fraction of the total shares allocated to the zone. For instance, if 2 zones share a processor set, each with 10 shares, then each zone will have a %SHR of 50%. %SHRU Of the share allocated to the zone, the fraction of resource used. Zones using all of their share will have a %SHRU of 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%.
Example 1: Summary of cpu and memory utilization every 5 seconds.
# zonestat -z global -r physical-memory 5 # zonestat 5 1 SUMMARY -----CPU------------- ----PHYSICAL--- ----VIRTUAL---- ZONE USED %PART %CAP %SHRU USED PCT %CAP USED PCT %CAP [total] 9.74 30% - - 7140M 21% - 10.6G 22% - [system] 0.28 0.8% - - 6535M 19% - 10.4G 21% - global 9.10 28% - - 272M 0.8% - 366M 0.7% - zoneA 0.32 1.0% - - 256M 0.7% - 265M 0.5% - zoneB 0.00 0.0% - - 77.6M 0.2% - 71.1M 0.1% -
Example 2: Using parseable output, fetching only zone usages.
The following command will produce parseable output, printing one line per zone using each pset resource for a 5 second interval. # zonestat -p -P zones -r psets 5 1
Example 3: Report on the default pset.
The following command will report on the default pset once a second for one minute. # zonestat -r default-pset 1 1m
Example 4: Report total and high utilization.
The following command monitors silently at a 10 second interval for 24 hours, producing a total and high report every 1 hour. # zonestat -q -R total,high 10s 24h 1h
The following exit values are returned:
0 Successful completion. 1 An error occurred. 2 Invalid usage. 3 svc:system/zones_monitoring:default not running or not responding.

The zonestat utility depends on the zones monitoring service:
If the zonestat service is stopped while the zonestat utility is running, the zonestat command invocation will quit without printing additional reports.
The reports (-R) will be printed if zonestat is interrupted (by ctrl-c, SIGINT) before reaching the next report period.
