[Xymon] External Powershell script not working

[Michael Schultheiss]

We've created an external powershell script for monitoring one of our
Exchange servers. The script has been listed in the externals section of
BBwin.cfg and we've verified the script is outputing to 
C:\Program Files (x86)\BBWin\tmp

but the results aren't showing up on the xymon server page.

We have other servers running external scripts but haven't been able to
determine the difference between the working external script and the
non-working one.

Powershell script:


Add-PSSnapin Microsoft.Exchange.Management.PowerShell.Admin -ErrorAction SilentlyContinue
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.Support -ErrorAction SilentlyContinue

$count = Get-TransportServer | Get-Message | Measure-Object | Select-Object Count -ExpandProperty Count
$sAlarm = "green"
$datetime = (Get-Date).ToString()

If ($count -gt 150) {
    $sAlarm = "yellow"
}    

$sAlarm,$datetime | Out-File -FilePath "C:\Program Files (x86)\BBWin\tmp\exchqueues"

Output:

green

BBwin.cfg snippet:


<externals>
	<setting name="timer" value="5m" />
	<setting name="logstimer" value="60" />
	<load value="C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -nologo -ExecutionPolicy Unrestricted -File 'C:\Program Files(x86)\BBWin\ext\exchqueues.ps1'" />
	<!-- externals launch examples
	<load value="cscript mybbscript.vbs" />
	<load value="myexternal.exe" />
	<load value="cscript wlbs.vbs" timer="15m" />
	<load value="cluster.exe" timer="90s" /> -->
</externals>
