Windows usage monitoring with PRTG Push sensor

Monitoring Windows usage (CPU, Memory, Disk Usage, Uptime) with HTTP Push Data Advanced PRTG Sensor.

It works better than WMI and it's cheaper on the sensor cost

Tested on

• Windows Server 2025 (built-in powershell)
• Windows 11 pro (built-in powershell)

Setup

Create a HTTP Push Data Advanced sensor in your PRTG and grab the Identification Token.

Download the script:

$sourceUrl = "https://raw.githubusercontent.com/stylersnico/prtg-windows-usage-push-monitoring/refs/heads/main/windows-usage.ps1"
$destinationPath = "C:\_Scripts\windows-usage.ps1"
if (-Not (Test-Path -Path ([System.IO.Path]::GetDirectoryName($destinationPath)))) {
    New-Item -ItemType Directory -Force -Path ([System.IO.Path]::GetDirectoryName($destinationPath))
}
Invoke-WebRequest -Uri $sourceUrl -OutFile $destinationPath

Edit it to put your PRTG IP and Identification token at the end.

Create a scheduled task that send the data every minute:

$taskName = "Windows_Usage_Monitor"
$scriptPath = "C:\_Scripts\windows-usage.ps1"
$action = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "-File `"$scriptPath`""
$trigger = New-ScheduledTaskTrigger -Once -At (Get-Date) -RepetitionInterval (New-TimeSpan -Minutes 1) -RepetitionDuration (New-TimeSpan -Days 365)
$settings = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -StartWhenAvailable
Register-ScheduledTask -TaskName $taskName -Action $action -Trigger $trigger -Settings $settings -Description "Windows Usage Monitor Script" -User "SYSTEM"

When the data is in PRTG, edit the alerting if needed (default values are built-in).
