   3 NAME
   4      zonestatd - zones monitoring daemon
   5 
   6 SYNOPSIS
   7      /usr/lib/zones/zonestatd
   8 
   9 DESCRIPTION
  10      zonestatd is a system daemon that is started during system boot.  It
  11      monitors the utilization of system resources by zones, as well as zone
  12      and system configuration information such as psrset psets, pool psets,
  13      and resource control settings.
  14 
  15      This daemon is started automatically by the zone management software and
  16      should not be invoked directly.  It does not constitute a programming
  17      interface, but is classified as a private interface.
  18 
  19 IMPLEMENTATION NOTES
  20      The zonestat service is managed by the service management facility,
  21      smf(5), under the service identifier:
  22 
  23            svc:/system/zones-monitoring:default
  24 
  25      Administrative actions on this service, such as enabling, disabling, or
  26      requesting restart, can be performed using svcadm(1M).  The service's
  27      status can be queried using the svcs(1) command.
  28 
  29      The zonestat service has the following SMF configuration property:
  30 
  31            config/sample_interval
  32 
  33            This property sets the zonestatd sample interval.  This is the
  34            interval used by the zones monitoring daemon, zonestatd to sample
  35            resource utilization.  This is also the interval used to determine
  36            configuration changes such as processor set changes, resource
  37            control changes, and zone state changes.
  38 
  39            The default interval is 5 seconds.
  40 
  41      The zonestat service makes use of extended accounting facility.  If not
  42      already enabled, it enables the tracking of process accounting resources,
  43      and configures a process accounting file.  The zonestat service will roll
  44      the process accounting log at its configured interval.
  45 
  46      If extended process accounting is enabled externally, the zonestat
  47      service will use the process accounting log as configured.  It will not
  48      roll the accounting log, but will operate correctly if the accounting log
  49      is rolled externally.
  50 
  51 INTERFACE STABILITY
  52      Private
  53 
  54 SECURITY
  55      The zonestat service in the global zone must be online for the zonestat
  56      service in each non-global zone (NGZ) to function properly.  The zonestat
  57      service in each NGZ does not directly read system configuration and
  58      utilization data, but rather reads from the zonestat service on the
  59      global zone.
