大規模測試連接Powershell

Question

好吧，我在PowerShell中的Test-Connection函數有問題。 我有一個csv文件，其列Server name和IPAddress 。 我需要使用信息服務器名稱 IPAddress Result創建連接報告。 如何添加有關列服務器名稱的信息？

我當前的代碼如下：

$Report = @()
$Servers = Import-CSV "C:\skrypt\bobi\servers.csv"  -Delimiter ';'
foreach ($Server in $Servers) {
    if ($Alive = Test-Connection -ComputerName $Server.IPAddress -Count 1 -quiet) {
        $TestResult = New-Object psobject -Property @{
            IPAddress = $Server.IPAddress
            Result    = "Online"
        }
    }
    else {
        $TestResult = New-Object psobject -Property @{
            IPAddress = $Server.IPAddress
            Result    = "Offline"
        }
    }
    $Report += $TestResult
}       
$Report | Select-Object IPAddress, Result | Export-Csv C:\skrypt\bobi\Report.csv -nti

Answer 1

我認為這可能對您有幫助：

$Servers = @(
    [PSCustomObject]@{
        'Server Name' = 'Server1'
        IPAddress = '10.10.10.10'
    }
    [PSCustomObject]@{
        'Server Name' = 'Wrong'
        IPAddress = '10.10.10.999'
    }
    [PSCustomObject]@{
        'Server Name' = 'Server2'
        IPAddress = '10.10.10.15'
    }
)

$Report = foreach ($Server in $Servers) {
    # First we collect all details we know in an object
    $Result = [PSCustomObject]@{
        Name   = $Server.'Server Name'
        IP     = $Server.IPAddress
        Online = $false
    }

    # Then we do the test
    if (Test-Connection -ComputerName $Server.IPAddress -Count 1 -Quiet) {
        # If the connection is successful, we set it to True
        $Result.Online = $true    
    }

    # As a last step we return the complete object
    # where it is collected in the array of Report
    $Result
}

$Report | Select-Object Name, IP, Online

如果您的CSV文件包含帶有主機名的列，則需要將PSCustomObject更改為：

$TestResult = New-Object psobject -Property @{
    IPAddress = $Server.IPAddress
    HostName = $Server.HostName #assuming column name is "HostName"
    Result    = "Result"
}

如果您的CSV文件中沒有帶有主機名的列，則需要使用其GetHostByAddress方法請求System.Net.Dns類。 像這樣：

$TestResult = New-Object psobject -Property @{
    IPAddress = $Server.IPAddress
    HostName = $([System.Net.Dns]::GetHostByAddress($Server.HostName).HostName -join ';')
    Result    = "Result"
}

在這兩種情況下，您都需要使用管道的HostName屬性來導出csv文件

$Report | Select-Object IPAddress, HostName, Result | Export-Csv C:\skrypt\bobi\Report.csv -nti
