Add columns for CSV output - powershell

Question

I have this PowerShell query listed below and I require the headers to be machine, path, filewalkmethod
$fs = Get-FileServer
foreach ($s in $fs) {
foreach ($share in $s.Volumes) {
($s.Servername, $share.Share, $share.FileWalkMethod) -join "," |
Out-File -Append D:\data\splunk\otl_varonis\otl_varonis_monitoring.csv
}
}
Sample output:
nas01e,E$,Windows
Updated Query I'm using:
Import-Module -Name VaronisManagement
Connect-Idu
$fs = Get-FileServer
foreach($s in $fs){
$s.Volumes | Select-Object #{n='ServerName'; e={$s.ServerName}}, Share, FileWalkMethod |
Export-CSV D:\data\splunk\otl_varonis\otl_varonis_monitoring_test.csv
-NoTypeInformation -NoClobber }

Answer 1

Untested but this should work:
foreach($s in $fs){
$s.Volumes | Select-Object #{n='Machine'; e={$s.ServerName}}, Share, FileWalkMethod | Export-CSV D:\data\splunk\otl_varonis\otl_varonis_monitoring.csv -NoTypeInformation -Append
}
Note that the parameter -Append for Export-Csv was introduced with PowerShell v3. To make this compatible with earlier versions you could pipeline the loop:
$fs | ForEach-Object {
$machine = $_.ServerName
$_.Volumes | Select-Object #{n='Machine';e={$machine}}, Share, FileWalkMethod
} | Export-Csv D:\data\splunk\otl_varonis\otl_varonis_monitoring.csv -NoType
