One really good powershell script is one a colleague sent me that emails me total disk space and free disk space for all servers listed in a text file:-
Have a look 🙂
# First lets create a text file, where we will later save the freedisk space info
$freeSpaceFileName = "<LOCATION>"
$serverlist = "<LOCATION>\Servers.txt"
$warning = 20
$critical = 10
$date = Get-Date -format d
New-Item -ItemType file $freeSpaceFileName -Force
# Getting the freespace info using WMI
#Get-WmiObject win32_logicaldisk | Where-Object {$_.drivetype -eq 3} | format-table DeviceID, VolumeName,status,Size,FreeSpace | Out-File FreeSpace.txt
# Function to write the HTML Header to the file
