the script can only be executed against one DRS cluster so change it accordingly to your need:
$clusterName = 'Production-Cluster01'
$stat = 'datastore.numberReadAveraged.average','datastore.numberWriteAveraged.average'
$esx = Get-Cluster -Name $clusterName | Get-VMHost
$dsTab = @{}
Get-Datastore -RelatedObject $esx | where {$_.Type -eq 'VMFS' -and $_.ExtensionData.Summary.MultipleHostAccess} | Sort-Object -Property Name -Unique | %{
$dsTab.Add($_.ExtensionData.Info.Vmfs.Uuid,$_.Name)
}
Get-Stat -Entity $esx -Stat $stat -Realtime -MaxSamples 1 |
Group-Object -Property Instance | %{
if($dsTab.ContainsKey($_.Name)){
New-Object PSObject -Property @{
Datastore = $dsTab[$_.Name]
ReadIOPS = $_.Group | where {$_.metricId -match 'read'} | Measure-Object -Property Value -Sum | Select -ExpandProperty Sum
WriteIOPS = $_.Group | where {$_.metricId -match 'write'} | Measure-Object -Property Value -Sum | Select -ExpandProperty Sum
}
}
} | ft -AutoSize
hope this helps.
