Low Disk storage Detection

Here's an example of how you can modify the PowerShell script to log low disk space events into the Event Viewer:

$driveLetter = 'C:' # Change this to your desired drive letter
$threshold = 80 # Change this to your desired threshold percentage

$disk = Get-WmiObject -Class Win32_LogicalDisk | Where-Object { $_.DeviceID -eq $driveLetter }
$freeSpacePercentage = [math]::Round(($disk.FreeSpace / $disk.Size) * 100, 2)

if ($freeSpacePercentage -le (100 - $threshold)) {
    $message = "Low disk space! Drive $driveLetter has $freeSpacePercentage% free space remaining."
    
    # Create a new event log entry in the Application log
    $eventParams = @{
        LogName = 'Application'
        Source = 'MyDiskSpaceMonitor'
        EventId = 1001 # You can use any valid Event ID here
        EntryType = 'Warning'
        Message = $message
    }
    New-EventLog @eventParams
}
