Return Codes? (was RE: Remotely Checking Windows: Mapped Network Drives)

[Robert Reeves]

Yeah, thanks...this whole exercise with VBScript has made me feel very
dirty and caused me to not think straight. Here's the final working
product...

'On Error Resume Next

DeviceName = WScript.Arguments.Item(0)
'Wscript.Echo "DeviceName=" & DeviceName
WarningPercentage = WScript.Arguments.Item(1)
'Wscript.Echo "WarningPercentage=" & WarningPercentage
CriticalPercentage = WScript.Arguments.Item(2)
'Wscript.Echo "CriticalPercentage=" & CriticalPercentage

Const intOK = 0
Const intWarning = 1
Const intCritical = 2
Const intUnknown = 3

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer &
"\root\cimv2")

Set colItems = objWMIService.ExecQuery("Select * from
Win32_MappedLogicalDisk WHERE DeviceID=""" & DeviceName & """")

For Each objItem in colItems
	PercentageFree = objItem.FreeSpace / objItem.Size
	PercentageFree = Int(PercentageFree * 100)
	
	If (PercentageFree <= Int(CriticalPercentage)) Then
		ReturnString = "CRITICAL"
		ReturnCode = intCritical
	ElseIf (PercentageFree <= Int(WarningPercentage)) Then
		ReturnString = "WARNING"
		ReturnCode = intWarning
	Else
		ReturnString = "OK"
		ReturnCode = intOK
	End If

	Wscript.Echo ReturnString & " " & objItem.DeviceID & " -
Percentage Free = " & PercentageFree & "% (" & objItem.FreeSpace & "/" &
objItem.Size & ")"	
	Wscript.Quit(ReturnCode)
Next

Yes, you do. The text response above is for human consumption only.
Nagios relies exclusively on the exit code of the plugin to determine
state.
