NAS Disk Volume Monitoring

Is the file share accessible from the Orion Server itself (ie. can you just open \\fileserver\share\directory from that server)?  If so, they can you can create a SAM template that uses a PowerShell script to get the size of the folder.  That's the way I would go, but then again, I almost always use PowerShell for things, so take my advice with a grain of NaCL.

The file share URL's are not available to the Orion Server, I was thinking about putting a Orion Agent on a server that did have access to \\fileserver\share\directory via WMI/Agent to performed the PowerShell script.  

Do you have any example or URL of a SAM PowerShell script to get the size of the folder?

I'm 90% sure that there's an example in the SAM Template Content Exchange (CX), but I always seem to write my own as I find new and better ways to do things in PowerShell.

This is quick and dirty - for more information about how I write PowerShell SAM templates, you can read:

# This is the Path to Check - you can also use the 'script parameters' in SAM and then use '$args[0]' as the variable.
$PathToCheck = "\\KMS-NAS\Documents"
# Get a list of all the files in the folder, recursively, and select only the Name and the Length (Size of the file)
# Use -Force to get files that also hidden or system files
$Files = Get-ChildItem -Path $PathToCheck -Recurse -Force -File | Select-Object -Property Name, Length
$FileCount = $Files.Count
# Get the size of all the files by summing the lengths of all the files.
$SizeInBytes = $Files | Measure-Object -Property Length -Sum | Select-Object -ExpandProperty Sum
# Write the output in the format:
# Message.(Element): Informational message about Element <-- Optional, but nice for readability
# Statistic.Element: ####
Write-Host "Message.Count: The '$PathToCheck' folder contains $( $FileCount ) file(s)."
Write-Host "Statistic.Count: $( $FileCount )"
Write-Host "Message.Size: The '$PathToCheck' folder is $( ( $SizeInBytes / 1GB ).ToString("0.00") ) GB"
Write-Host "Statistic.Size: $SizeInBytes"
# Exit with a 0 indicates that it ran clean.  This should probably have some other logic for error-trapping (folder does not exist, don't have access to files, etc.
exit(0)

On my computer, it returns:

Message.Count: The '\\KMS-NAS\Documents' folder contains 77477 file(s).
Statistic.Count: 77477
Message.Size: The '\\KMS-NAS\Documents' folder is 218.72 GB
Statistic.Size: 234847859171

If it were me, I might also add a "how long it took to enumerate the file share" because that may be an interesting metric for me.  For something like this, I wouldn't poll very frequently (if there are a bunch of files) - maybe once an hour or less.

thanks for the help, I will try out the scrip and see what I get back from the scrip
