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 serverthe local

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

-CimSession

-Clear

-ComputerName

-ThrottleLimit

-ZoneName
