Monitoring Hyper-V Host Cluster shared volume and Failover Cluster Management using azure log analytics

Question

We have a Hyper-V host and fail-over cluster where Cluster shared volume is created and all the virtual machines created in the Hyper-V host uses the cluster shared volume.

Our ultimate aim is to monitor the CSV- Cluster shared volume's space utilization. We have installed Microsoft monitoring agent in the hyper-v host and in the Log analytics workspace is configured to get the "% Free Space" for the host with the help of Windows performance counters.

The performance counter shows space utilization for C drive. but not the cluster shared volume, as it is inside the C drive. like, C:\Volume1\

Help me here to monitor the space utilization for CSVFS for Hyper-V.

Answer

Hi，
To monitor the free space of a CSV volume, you could open Failover Cluster Manager - Storage - Disks

Or you could use powershell script, like this

Import-Module FailoverClusters  
  
$objs = @()  
  
$csvs = Get-ClusterSharedVolume  
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  
      }  
      $objs += $obj  
   }  
}  
  
$objs | ft -auto Name,Path,@{ Label = "Size(GB)" ; Expression = { "{0:N2}" -f ($_.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) } }
