powershell arguments with nrpe

Question

I want to pass two arguements with a powershell-script.

This is the regular check

test = cmd /c echo scripts\test.ps1 ; exit($lastexitcode) | powershell.exe -command -

This is the idea that i want. To set warning and critical.

test = cmd /c echo scripts\test.ps1 -w 10 -c 50 ; exit($lastexitcode) | powershell.exe -command -

If warning is set to over 10 then it will return exit 1

If critical is set over 50 then it will return exit 2

Not sure howto do this in my script.

Here is how it looks now.

$condition = (Get-Service | Where-Object Status -eq "Running").Count

if ($argument warn) {
    Write-Output "Warning:" $condition
    exit 1 
}

ElseIf ($argument critical) {
        Write-Output "Critical:" $condition
        exit 2
}

Although I'm not quite sure if this is what you mean, but you can start the script with a param() block so it accepts arguments like

param (
    [int]$WarningLevel = 0,
    [int]$CriticalLevel = 0
)

$condition = (Get-Service | Where-Object {$_.Status -eq "Running"}).Count

if ($CriticalLevel -gt 0 -and $condition -gt $CriticalLevel) {
    Write-Output "Critical: Way too many proc's: $condition"
    Exit 2
}
elseif ($WarningLevel -gt 0 -and  $condition -gt $WarningLevel) {
    Write-Output "Warning: proc's filling up: $condition"
    Exit 1 
}
Write-Output "All OK"
Exit 0
