How to add hardcoded value to WMI output in Powershell - sql

Question

I am new to powershell, i am trying to retrieve the SQL Services details using WMI object. My code is as follows:
$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
}
}
My Output will come something like this:
Instance Name:
ABCDEFGH
Name Startmode State
SQLdmCollectionService$Default Auto Stopped
SQLdmManagementService$Default Auto Stopped
SQLdmPredictiveAnalyticsService$Default Auto Stopped
My question is, how to add a additional column to the output and add custom text as values.
I want to add remarks column and display failed if any services are stopped.
Name Startmode State Remarks
SQLdmCollectionService$Default Auto Stopped Failed
SQLdmManagementService$Default Auto Stopped Failed
SQLdmPredictiveAnalyticsService$Default Auto Stopped Failed

Answer 1

Your columns are defined by what you put in Select-Object, as you only have Name, Startmode and State those will be the columns.
Change
Select Name,Startmode,State
To
Select-Object Name,Startmode,State,Remark
By adding another property called Remarks you will effectively add another column to your output and you can change the value of Remark by calling the property like so
$Servicestate.Remark = 'Failed'
So you're final code might look something like this
$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
}
}

When assigning your values to $servicestate you can pipe to a Select command and create an extra value with a hashtable. Check out this slightly modified version of your script, paying close attention to line 9:
$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
}
}
