Monitoring Registry Key for Pending Reboot

We are wanting to monitor whether a server has a pending reboot or not. To do so we have a script that sets a registry key to 1 if a reboot is needed or 0 if not. I found a powershell script for a similar need and modified it, but I can't seem to get it to work. It is returning a blank ' ' and showing unknown when testing. Is there something I'm missing?

Arguments:
HKLM:\SOFTWARE\SW-Reg-Check\PendingReboot,1

param(
[string]$reg,
[string]$Key,
$target_value
)

$reg_value = Get-ItemProperty $reg -name $Key

Write-Host "Message: '$reg' is currently set to '$reg_value'"
if ($reg_value -match "$key=$target_value") {
Write-Host "Statistic: 0"
} else {
Write-Host "Statistic: 1"
}
Exit 0

Are you monitoring the node via AGENT or WMI? What is the method in your SAM Component - Local or Remote? When you browse the Registry on the Node, can you see that Key and the Setting?

Also your script is expecting 3 Arguments while you are only passing it 2

When I Hard-Code the Parameters/Variables this works on my end:

param(
[string]$reg = "HKLM:\SOFTWARE\SW-Reg-Check",
[string]$Key = 'PendingReboot',
$target_value = 1
)

$reg_value = Get-ItemProperty $reg -name $Key
$KeyValue = $reg_value.PendingReboot
Write-Host "Message: '$reg' is currently set to '$KeyValue' "
if ($KeyValue -match $target_value) {
Write-Host "Statistic: 0"
} else {
Write-Host "Statistic: 1"
}
Exit 0
