3. Basic knowledge of PowerShell commands


Prepare the environment – Get Ready

Create a root folder and three child folders like:
1. Root folder name: DiskUsage
2. Child folders name: DiskUsageReports, DiskUsageReportScript, and ServersList

A reference screenshot is given below:







Prepare a text file with Name ServersList.txt and place it in ServersList folder. This text file should contain the list of windows machines you wish to export disk usage report.

You can use name or IP as shown in below screenshot:















Finally, create the PowerShell script with following commands.

Simply copy and paste the given commands in PowerShell ISE windows and save it as .ps1 file under DiskUsageScript folder with name DiskUsageReport.ps1

===============================================================

$OldReports = (Get-Date).AddDays(-30)
Get-ChildItem D:\DiskUsage\DiskUsageReports\*.* | `
Where-Object { $_.LastWriteTime -le $OldReports} | `
Remove-Item -Recurse -Force -ErrorAction SilentlyContinue 
$LogDate = get-date -f yyyyMMddhhmm
$File = Get-Content -Path D:\DiskUsage\ServersList\ServersList.txt
$DiskReport = ForEach ($Servernames in ($File))

{Get-WmiObject win32_logicaldisk <#-Credential $RunAccount#> `
-ComputerName $Servernames -Filter "Drivetype=3" `
-ErrorAction SilentlyContinue
}

$DiskReport |

Select-Object @{Label = "Server Name";Expression = {$_.SystemName}},
@{Label = "Drive Letter";Expression = {$_.DeviceID}},
@{Label = "Total Capacity (GB)";Expression = {"{0:N1}" -f( $_.Size / 1gb)}},
@{Label = "Free Space (GB)";Expression = {"{0:N1}" -f( $_.Freespace / 1gb ) }},
@{Label = 'Free Space (%)'; Expression = {"{0:P0}" -f ($_.freespace/$_.size)}} |
