zonestatd(1M) -- zones monitoring daemon
zonestatd is a system daemon that is started during system boot.
It monitors the utilization of system resources by zones, as well
as zone and system configuration information such as psrset psets,
pool psets, and resource control settings.
This daemon is started automatically by the zone management
software and should not be invoked directly. It does not
constitute a programming interface, but is classified as a
The zonestat service in the global zone must be online for the
zonestat service in each non-global zone (NGZ) to function
properly. The zonestat service in each NGZ does not directly read
system configuration and utilization data, but rather reads from
the zonestat service on the global zone.

The zonestat service is managed by the service management
facility, smf(5), under the service identifier:
Administrative actions on this service, such as enabling,
disabling, or requesting restart, can be performed using
svcadm(1M). The service's status can be queried using the
The zonestat service has the following SMF configuration property:
This property sets the zonestatd sample interval. This is the
interval used by the zones monitoring daemon, zonestatd(1M) to
sample resource utilization. This is also the interval used to
determine configuration changes such as processor set changes,
resource control changes, and zone state changes.
The default interval is 5 seconds.
The zonestat service makes use of extended accounting facility. If
not already enabled, it enables the tracking of process accounting
resources, and configures a process accounting file. The zonestat
service will roll the process accounting log at its configured
interval (see zonestatd(1M)).
If extended process accounting is enabled externally, the zonestat
service will use the process accounting log as configured. It
will not roll the accounting log, but will operate correctly if
the accounting log is rolled externally.
