Qualifiers: Key

Key of a CIM_System instance in an enterprise environment.

This property is inherited from CIM_ManagedSystemElement.

NameFormat

Data type: string

Access type: Read-only

Computer system Name value that is generated automatically. The CIM_ComputerSystem object and its derivatives are top-level objects of the Common Information Model (CIM). They provide the scope for several components. Unique CIM_System keys are required, but you can define a heuristic to create the CIM_ComputerSystem name that generates the same name, and is independent from the discovery protocol. This prevents inventory and management problems when the same asset or entity is discovered multiple times, but cannot be resolved to one object. Using a heuristic is recommended, but not required.

The heuristic is outlined in the CIM V2 Common Model specification, and assumes that the documented rules are used to determine and assign a name. The NameFormat values list defines the order to assign a computer system name. Several rules map to the same value.

The CIM_ComputerSystem Name value that is calculated using the heuristic is the key value of the system. However, use aliases to assign a different name for CIM_ComputerSystem, which can be more unique to your company.

This property is inherited from CIM_System.

Remarks

To determine the total number of processor instances associated with a computer system object, use the Win32_ComputerSystemProcessor association class.

A Win32_ComputerSystem instance that has multiple physical processors has multiple Win32_Processor instances associated with it. If the value of NumberOfLogicalProcessors is greater than the value of NumberOfProcessors then the computer system is either a multicore system or has one or more processors enabled for hyperthreading. For more information, see the NumberOfLogicalProcessors and NumberOfCores properties and Remarks section in Win32_Processor.

The Win32_ComputerSystem class is derived from CIM_UnitaryComputerSystem.

Examples

You can find an example script that obtains operating system and processor data from Win32_ComputerSystem, Win32_Processor, and Win32_OperatingSystem in the Win32_Processor topic examples.

The following VBScript sample describes how to retrieve the domain name of the local machine from instances of Win32_ComputerSystem.

Set SystemSet = GetObject("winmgmts:").InstancesOf ("Win32_ComputerSystem")

for each System in SystemSet
 WScript.Echo System.Domain
next

The following Perl sample describes how to retrieve the local machine name from instances of Win32_ComputerSystem.

use strict;
use Win32::OLE;

my ($SystemSet, $System);  
eval {$SystemSet = Win32::OLE->GetObject("winmgmts:{impersonationLevel=impersonate}!\\\\.\\root\\cimv2")->

 {
  print "\n", $System->{Domain}, "\n";

else
{
 print STDERR Win32::OLE->LastError, "\n";
}

The following Perl sample describes how to retrieve the DNS domain name of the local machine from instances of Win32_ComputerSystem.

 ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled=true"); };
if (!$@ && defined $NICSet)
{
 foreach $NIC (in $NICSet)
 {
  if(defined $NIC->{DNSDomain})
