如何在 Powershell 中将硬编码值添加到 WMI 输出

Question

我是 powershell 新手，我正在尝试使用 WMI 对象检索 SQL 服务详细信息。我的代码如下：

---

$InputFile = Import-Csv "C:\input\Servers.csv" | %{ $_.Instance = $_.Instance -replace "\\.*?$" ; $_}
Write-Output "SQL Services details for Server:" | Out-File C:\output\SQLCHECK.STOPPED.LOG 
Write-Output "********************************" | Out-File C:\output\SQLCHECK.STOPPED.LOG  -Append
foreach($Servers in $Inputfile)
{

Write-Output $Servers|ft -AutoSize | Out-File C:\output\SQLCHECK.STOPPED.LOG 
$Servicesstate=Get-WmiObject win32_service  -ComputerName $Servers.instance  | Select Name, Startmode, State  | Where-Object `
{$_.name -like "*SQL*" -and $_.Startmode -match "Auto" -and $_.state -match "Stopped"} | ft -auto 
if (!$Servicesstate )
{
Write-Host "No Services in STOP state"
Write-Output "No Services in STOPPED state" | Out-File C:\output\SQLCHECK.STOPPED.LOG -Append
}
Else
{
echo ($Servicesstate )
Write-Output ($Servicesstate)  | Out-File C:\output\SQLCHECK.STOPPED.LOG  -Append
}
}

---

我的输出会是这样的：

Instance Name:
ABCDEFGH

Name                                    Startmode State  

SQLdmCollectionService$Default          Auto      Stopped
SQLdmManagementService$Default          Auto      Stopped
SQLdmPredictiveAnalyticsService$Default Auto      Stopped

---

我的问题是，如何在输出中添加额外的列并将自定义文本添加为​​值。

我想添加备注栏，如果有服务停止显示失败。

---

Name                                    Startmode State   Remarks

SQLdmCollectionService$Default          Auto      Stopped  Failed
SQLdmManagementService$Default          Auto      Stopped  Failed
SQLdmPredictiveAnalyticsService$Default Auto      Stopped  Failed

Answer 1

您的列由您在 Select-Object 中输入的内容定义，因为您只有 Name、Startmode 和 State，这些将是列。

改变

Select Name,Startmode,State

到

Select-Object Name,Startmode,State,Remark

通过添加另一个名为 Remarks 的属性，您将有效地在输出中添加另一列，您可以通过调用该属性来更改 Remark 的值

$Servicestate.Remark = 'Failed'

所以你的最终代码可能看起来像这样

$InputFile = Import-Csv "C:\input\Servers.csv" | %{ $_.Instance = $_.Instance -replace "\\.*?$" ; $_}
Write-Output "SQL Services details for Server:" | Out-File C:\output\SQLCHECK.STOPPED.LOG 
Write-Output "********************************" | Out-File C:\output\SQLCHECK.STOPPED.LOG  -Append
foreach($Servers in $Inputfile)
{

Write-Output $Servers|ft -AutoSize | Out-File C:\output\SQLCHECK.STOPPED.LOG 
$Servicesstate=Get-WmiObject win32_service  -ComputerName $Servers.instance  | Select Name, Startmode, State  | Where-Object `
{$_.name -like "*SQL*" -and $_.Startmode -match "Auto" -and $_.state -match "Stopped"} | ft -auto 
if (!$Servicesstate )
{
    # Edit the new column before you output
    $Servicestate.Remark = 'Failed'
    Write-Host "No Services in STOP state"
    Write-Output "No Services in STOPPED state" | Out-File C:\output\SQLCHECK.STOPPED.LOG -Append
}
Else
{
    # Edit the new column before you output
    $Servicestate.Remark = 'Success'
    echo ($Servicesstate )
    Write-Output ($Servicesstate)  | Out-File C:\output\SQLCHECK.STOPPED.LOG  -Append
}
}

将您的值分配给$servicestate 时，您可以通过管道传递给Select 命令并使用哈希表创建一个额外的值。查看脚本的这个稍作修改的版本，密切注意第 9 行：

$InputFile = Import-Csv "C:\input\Servers.csv" | %{ $_.Instance = $_.Instance -replace "\\.*?$" ; $_}
Write-Output "SQL Services details for Server:" | Out-File C:\output\SQLCHECK.STOPPED.LOG 
Write-Output "********************************" | Out-File C:\output\SQLCHECK.STOPPED.LOG  -Append
foreach($Servers in $Inputfile)
{

    Write-Output $Servers|ft -AutoSize | Out-File C:\output\SQLCHECK.STOPPED.LOG 
    $Servicesstate=Get-WmiObject win32_service  -ComputerName $Servers.instance  | Select Name, Startmode, State  |
    Where{$_.name -like "*SQL*" -and $_.Startmode -match "Auto" -and $_.state -match "Stopped"}|Select Name,Startmode,State,@{l='Remarks';e={if($_.State -eq "Stopped"){"Failed"}}}
    if (!$Servicesstate )
    {
        Write-Host "No Services in STOP state"
        Write-Output "No Services in STOPPED state" | Out-File C:\output\SQLCHECK.STOPPED.LOG -Append
    }
    Else
    {
        echo ($Servicesstate|ft -AutoSize )
        Write-Output ($Servicesstate)  |FT -auto| Out-File C:\output\SQLCHECK.STOPPED.LOG  -Append
    }
}
