Automate getting file share info such as name and used/free space for all servers in a domain

Anyone have any suggestions on how to do this? I've looked into using Powershell but most servers are older and the Get-SMBShare command doesn't work. Also I tried using WMI with powershell but didn't have any luck.  I have access to SCOM and SCCM if needed, but I've never really used them before. Also, is it possible to email a report weekly?

For free space, I use wmi in a .bat file.

Make ServerNames.txt. In it put server names. e.g.:

Open in new window

Make FindSpace.bat. This sends results to FindSpace_WMIC.txt:
@echo off
set FNStns=ServerNames.txt
set FNWMICOutput=%~n0_WMIC.txt
if exist "%FNWMICOutput%" del "%FNWMICOutput%"
wmic /output:"%FNWMICOutput%" /node:@"%FNStns%" logicaldisk where DriveType="3" get caption,VolumeName,VolumeSerialNumber,Size,FileSystem,FreeSpace /format:csv

Open in new window

You can run this .bat as a weekly scheduled task.

For emailing, I use the free mailer BLAT
Once you've confirmed the wmic code works, add this to the .bat:

set to=-to
set from=-f
set subject=-s "Server free space"
set body=-body "See "%FNWMICOutput%" for more info"
set attach=-attacht "%FNWMICOutput%"
blat %from% %mailsvr% %to% %subject% %body% %attach%

You have several options;

SCOM - requires you to create a rule to check for disk space as last time I looked it did not come with one out of the box

SCCM - runs hardware inventory, which updates every 7 days, so you should already have the data
there is a report you can run that provides that and more called

Computers with low free disk space (< % free)

which is the nearest fit. Otherwise you have to create your own report. Note with SCCM you can create a Subscription which will then email a file as XML,CSV,HTML,PDf or Excel on a schedule.

PowerShell/VBscript/Bat - as above but they will all use WMI to read the info. Even SCCM & SCOM will use the WMI anyway. That's what it's for.

Hi Blake,

What about the Powershell to get all Hard drive size for some servers type or in a special OU ?

would that be useful for you ?

Save the below as .BAT file and then run scheduled tasks to run every X amount of time according to your need:

@PowerShell.exe -ExecutionPolicy RemoteSigned -Command "Invoke-Expression -Command ((Get-Content -Path '%~f0' | Select-Object -Skip 2) -join [environment]::NewLine)"
@exit /b %Errorlevel%

# Issue warning if % free disk space is less
$percentWarning = 5;
# Get server list
$servers =  Get-ADComputer -Properties Name  -Filter {Enabled -eq $True -and OperatingSystem -like "*Windows Server*"} -SearchBase "OU=Servers,DC=domain,DC=com" |
	        Where-Object {Test-Connection $_.Name -Count 1 -Quiet} |
	        Where-Object { (Get-WmiObject -Class Win32_BIOS -ComputerName $_.Name ).SerialNumber -notlike "VMware*"} |
	        Select-Object -ExpandProperty Name

$datetime = (Get-Date).ToString()
# How many servers
$server_count = $servers.Length;
# processed server count
$i = 0;
foreach($server in $servers) {
	$server_progress = [int][Math]::Ceiling((($i / $server_count) * 100))
	# Parent progress bar
	Write-Progress -Activity "Checking $server" -PercentComplete $server_progress -Status "Processing servers - $server_progress%" -Id 1;
	Sleep(1); # Sleeping just for progress bar
	# Get fixed drive info
	$disks = Get-WmiObject -ComputerName $server -Class Win32_LogicalDisk -Filter "DriveType = 3";
 	# How many disks are there?
	$disk_count = $disks.Length;
 	$x = 0; 
	foreach($disk in $disks) {
		$disk_progress = [int][Math]::Ceiling((($x / $disk_count) * 100));
		$disk_name = $disk.Name;
		$volumename = $disk.VolumeName;
		Write-Progress -Activity "Checking disk $disk_name" -PercentComplete $disk_progress -Status "Processing server disks - $disk_progress%" -Id 2;
		$deviceID = $disk.DeviceID; 
		[float]$size = $disk.Size;
		[float]$freespace = $disk.FreeSpace;
		$percentFree = [Math]::Round(($freespace / $size) * 100, 2);
		$sizeGB = [Math]::Round($size / 1073741824, 2);
		$freeSpaceGB = [Math]::Round($freespace / 1073741824, 2);
 		$usedGB = $sizeGB - $freeSpaceGB
		$colour = "Green";
		if($percentFree -lt $percentWarning) {
			$colour = "Red";
            $mailsubject = "Disk space low on " + $server + " - " + "$deviceID drive" +  " - free space ($freeSpaceGB GB)" + " - percentage free space = $percentFree %"
			$mailbody = "$server $deviceID - disk size - $volumename ($sizeGB GB), used space ($usedGB GB), free space ($freeSpaceGB GB), percentage free space = $percentFree %, as at $datetime"
            Send-MailMessage -Body $mailbody -To -From -SmtpServer -Subject $mailsubject
		if ( $volumename -eq "" ) {
			$volumename = "*"
		Write-Host -ForegroundColor $colour "$server $deviceID - disk size - $volumename ($sizeGB GB), used space ($usedGB GB), free space ($freeSpaceGB GB), percentage free space = $percentFree %";
	# Finish off the progress bar
	Write-Progress -Activity "Finished checking disks for this server" -PercentComplete 100 -Status "Done - 100%" -Id 2;
	Sleep(1); # Just so we see some progress!
	Write-Host ""
Write-Progress -Activity "Checked all servers" -PercentComplete 100 -Status "Done - 100%" -Id 1;

Open in new window

it will send out email per server based on certain threshold limit, in this case is 5% empty disk space.
