Get-IpamDhcpConfigurationEvent
Gets configuration events for DHCP servers from the IPAM database.
Syntax
Get-IpamDhcpConfigurationEvent
[-ServerName <String[]>]
[-StartDate <DateTime>]
[-EndDate <DateTime>]
[-CimSession <CimSession[]>]
[-ThrottleLimit <Int32>]
[-AsJob]
[<CommonParameters>] Description
The Get-IpamDhcpConfigurationEvent cmdlet gets configuration events for Dynamic Host Configuration Protocol (DHCP) servers from the IP Address Management (IPAM) database. You can specify fully qualified domain names (FQDNs) of DHCP servers, a start date, and an end date. If you do not specify a DHCP server, the cmdlet gets configuration events for all servers.
Use the Remove-IpamDhcpConfigurationEvent cmdlet to remove events from the database.
If you do not specify a start date, the cmdlet uses the date of the first IPAM configuration event in the database. If you do not specify an end date, the cmdlet uses the date of the last IPAM configuration event. All dates use the time zone of the IPAM server.
If there are more than 10,000 results for a command, the cmdlet returns only 10,000. The cmdlet warns that this is a partial result.
Examples
Example 1: Get events for all servers for a date range
PS C:\> $Today = Get-Date
PS C:\> $StartDate= $Today.AddDays(-7)
PS C:\> Get-IpamDhcpConfigurationEvent -EndDate $Today -StartDate $StartDate | Export-Csv "C:\IpamEvents.csv"This example gets the configuration events for all DHCP servers, and then saves them as a .csv file.
The first command creates a DateTime object by using the Get-Date cmdlet, and then stores it in the $Today variable.
By default, Get-Date creates the current date.
For more information about Get-Date and DateTime objects, type Get-Help Get-Date.
The second command stores a new DateTime object in the $StartTime variable. That date is seven days prior to the date stored in the $Today variable.
The third command gets configuration events between the start date, stored in the $StartTime variable, and the end date, stored in the $Today variable, for all DHCP servers.
The command passes the events to the Export-Csv cmdlet through the pipeline operator.
That cmdlet saves the results as a .csv file.
For more information about this cmdlet, type Get-Help Export-Csv.
Example 2: Get events for specified servers for a date range
PS C:\> $Today = Get-Date
PS C:\> $StartDate= $Today.AddDays(-7)
PS C:\> Get-IpamConfigurationEvent -EndDate $Today -ServerName "dhcp01.contoso.com","dhcp02.contoso.com" -StartDate $StartDate | Export-Csv "C:\IpamFilteredEvents.csv"This example gets the configuration events for two DHCP servers, and then saves them as a .csv file.
The first command creates a DateTime object by using the Get-Date cmdlet, and then stores it in the $Today variable.
The second command stores a new DateTime object in the $StartTime variable. That date is seven days prior to the date stored in the $Today variable.
The third command gets configuration events between the start date, stored in the $StartDate variable, and the end date, stored in the $Today variable. The command specifies the FQDNs of two DHCP servers. The command passes the events to the Export-Csv cmdlet through the pipeline operator. That cmdlet saves the results as a .csv file.
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 |
| Required: | False |
| 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 |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-EndDate
Specifies the end date as a DateTime object.
The cmdlet gets events through this date from the IPAM database.
To obtain a DateTime object, use the Get-Date cmdlet and specify the date in DD/MM/YYYY format.
For more information, type Get-Help Get-Date.
| Type: | DateTime |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ServerName
Specifies an array of FQDNs of DHCP servers.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-StartDate
Specifies the start date as a DateTime object. The cmdlet gets events beginning with this date. To obtain a DateTime object, use the Get-Date cmdlet and specify the date in DD/MM/YYYY format.
| Type: | DateTime |
| Position: | Named |
| Default value: | None |
| Required: | False |
| 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.

Outputs
