Add column to CSV file with powershell AzureVM - powershell

Question

Not sure how to explain this, we're doing an assessment on disk usage on Azure, to reduce costs. We are trying to asses the space on each vm and reduce the disks
I'd like to add a recommendation column in there based on the free space, if the freespace is greater than 90% then add a comment "consider resizing" if less than 15% then "consider disk clean up".
The script I have works fine except it doesn't add the comment in, first I tried this...
$computers = (Get-AdComputer -Filter "name -like 'VM-*'").Name | Sort-Object
foreach ($computer in $Computers)
{
$vol = gwmi Win32_volume -Computer $Computer -Filter 'DriveType = 3'
#$vol
$info = $vol | select PsComputerName, DriveLetter, Label,
#{n='Capacity';e={[int]($_.capacity/1GB)}},
#{n='FreeSpace';e={[int]($_.FreeSpace/1GB)}},
#{n='FreeSpace (%)';e={[int](($_.FreeSpace) / ($_.capacity) * 100.0)}}
if ('FreeSpace (%)' -gt 85)
{
Write-Output "Disk Usage Low, Consider Resizing Options"
}
else
{
Write-Output "Disk Usage High"
}
$info | Export-Csv "c:\temp\tempfiles\question.csv" -Append
}
That didn't work, I then tried adding another section, where I get true or false, which seems to work.. that one is below, however I need to dd recommendations in..
$computers = (Get-AdComputer -Filter "name -like 'VM-*'").Name | Sort-Object
foreach ($computer in $Computers)
{
$vol = gwmi Win32_volume -Computer $Computer -Filter 'DriveType = 3'
#$vol
$info = $vol | select PsComputerName, DriveLetter, Label,
#{n='Capacity';e={[int]($_.capacity/1GB)}},
#{n='FreeSpace';e={[int]($_.FreeSpace/1GB)}},
#{n='FreeSpace (%)';e={[int](($_.FreeSpace) / ($_.capacity) * 100.0)}},
#{n='Recommendation';e={[String] ($_.FreeSpace -gt 90)}}
$info | Export-Csv "c:\temp\tempfiles\question.csv" -Append
}
Hope that makes sense.
Thanks in advance :)

Answer 1

The e stands for Expression. So you should be able to use an expression in there, using the original object properties (i.e. not your custom property names such as FreeSpace (%))
$computers = (Get-AdComputer -Filter "name -like 'VM-*'").Name | Sort-Object
foreach ($computer in $Computers)
{
$vol = gwmi Win32_volume -Computer $Computer -Filter 'DriveType = 3'
#$vol
$info = $vol | select PsComputerName, DriveLetter, Label,
#{n='Capacity';e={[int]($_.capacity/1GB)}},
#{n='FreeSpace';e={[int]($_.FreeSpace/1GB)}},
#{n='FreeSpace (%)';e={[int](($_.FreeSpace) / ($_.capacity) * 100.0)}},
#{n='Recommendation';e={
if((($_.FreeSpace) / ($_.capacity) * 100.0) -gt 90){
"Disk Usage Low, Consider Resizing Options"
}elseif((($_.FreeSpace) / ($_.capacity) * 100.0) -gt 75){
"Something else"
}else{
"Disk Usage High"
}
}
$info | Export-Csv "c:\temp\tempfiles\question.csv" -Append
}
