ZONESTATD(8) Maintenance Commands and Procedures ZONESTATD(8)

NAME

zonestatd - 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.

IMPLEMENTATION NOTES

The zonestat service is managed by the service management facility,
smf(7), 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(8). 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 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.

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.

INTERFACE STABILITY

Private

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.
