  You may develop a script base on the SCOM management pack or use powershell comandlet - read this blog.

  Thanks for the blog. Was wondering if there is any other method to find that information especially thru perfmon, since we need to integrate it with our Server monitoring suite, which can easily pick up the info from perfmon.

  Hi,

  This blog gives you a PowerShell script to monitor CSV disk space: http://blogs.msdn.com/b/clustering/archive/2010/06/19/10027366.aspx

  This blog gives an overview of the CSV Perfmon counters, which are much more granular: http://blogs.msdn.com/b/clustering/archive/2009/10/02/9902218.aspx

  Thanks!

  param
  (
  [string]$ClusterName = $(Throw "Cluster name required"),
  [int]$SpaceThreshold = $(Throw "Freespace alert percentage required")

  Import-Module FailoverClusters
  
  $objs = @()

  $csvs = Get-ClusterSharedVolume -Cluster $ClusterName
  foreach ( $csv in $csvs )

     $csvinfos = $csv | select -Property Name -ExpandProperty SharedVolumeInfo
     foreach ( $csvinfo in $csvinfos )
     {
        $obj = New-Object PSObject -Property @{
           Name        = $csv.Name
           Path        = $csvinfo.FriendlyVolumeName
           Size        = $csvinfo.Partition.Size
           FreeSpace   = $csvinfo.Partition.FreeSpace
           UsedSpace   = $csvinfo.Partition.UsedSpace
           PercentFree = $csvinfo.Partition.PercentFree
        }
           if ($obj.PercentFree -le $SpaceThreshold) {$alert++}
  
        $objs += $obj
     }
  }
  Write-Host "Cluster: " $ClusterName
  $objs | ft -auto Name,Path,@{ Label = "Size(GB)" ; Expression = { "{0:N2}" -f ($_.Size/1024/1024/1024) } },@{ Label = "FreeSpace(GB)" ; Expression = { "{0:N2}" -f ($_.FreeSpace/1024/1024/1024) } },@{ Label = "UsedSpace(GB)" ; Expression = { "{0:N2}" -f ($_.UsedSpace/1024/1024/1024) } },@{ Label = "PercentFree" ; Expression = { "{0:N2}" -f ($_.PercentFree) } }
  If ($alert -gt 0){Write-Host "WARNING: One or more drives have exceeded the threshold value of" $SpaceThreshold "% remaining!"}
  return $alert

  Symon - I found the script you posted on the blog to be very useful.  Thank you to you and/or whoever wrote it.

  I have modified the script from your blog post so it can be run from a machine that isn't the Hyper-V host, and to compare the percent free column to a parameter specified by the user. It also returns a value indicating the number of drives exceeding the specified threshold, which might be useful to integrate into some kind of scheduled process.

  Hopefully this is useful for someone.
