zonestatd(1M) -- zones monitoring daemon

SYNOPSIS

 /usr/lib/zones/zonestatd

DESCRIPTION

 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
 private interface.

SECURITY

 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.

ATTRIBUTES

 See attributes(5) for descriptions of the  following  attri-
 butes:

NOTES

The zonestat service is managed by  the  service  management
facility, smf(5), under the service identifier:

  svc:/system/zones-monitoring:default

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
svcs(1) command.

The zonestat service has the following SMF configuration property:

  config/sample_interval

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.
You can’t perform that action at this time.
