   [-CimSession <CimSession[]>]
   [-ThrottleLimit <Int32>]
   [-AsJob]
   [<CommonParameters>]
Get-DnsServerStatistics
   [-ComputerName <String>]

Description

The Get-DnsServerStatistics cmdlet retrieves statistics of a Domain Name System (DNS) server. If the ZoneName parameter is specified, this cmdlet gets statistics for the zones specified by that parameter. If the ZoneName parameter is not specified, the cmdlet gets aggregated server level statistics.

If the Clear parameter is specified along with the ZoneName parameter, the statistics for the specified zone will also be cleared.

Examples

Example 1: Get server statistics for a the local DNS server

PS C:\> Get-DnsServerStatistics

This command gets server statistics for the local DNS server.

Example 2: Get server statistics for a specific zone

PS C:\> Get-DnsServerStatistics -ZoneName "contoso.com"

This command gets the statistics for the DNS zone named contoso.com.

Example 3: Clear statistics for a specific zone

PS C:\> Get-DnsServerStatistics -ZoneName "contoso.com" -Clear

This command gets the current zone statistics and resets the statistics counter for the DNS zone named contoso.com.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Clear

Indicates that the cmdlet clears statistics for the zones that you specify in the ZoneName parameter.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ComputerName

Specifies a DNS server. The acceptable values for this parameter are: an IP V4 address; an IP V6 address; any other value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

Type:String
Aliases:Cn
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ZoneName

Specifies an array of names of DNS zones for which to get DNS statistics. This parameter is mandatory for the ZoneStatistics parameter set.

Type:String[]
Position:Named
Default value:None
Accept pipeline input:True
Accept wildcard characters:False
