Storage team said the best practics of QFullSampleSize is 32, they want to check how it’s going in our environment. It’s easy to check individual host, but pretty time consuming if you want to check 300+ hosts.
Here is a one line PowerShell script to export QFullSampleSize and QFullThreshold to a csv file.
Get-VMHost | %{ $HostName=$_.Name; $HostCluster=$_.Parent; Get-VMHostAdvancedConfiguration -VMHost $_ | % { $_.getEnumerator()| ? {$_.Key -like "*QFull*"} | select Name,Value,@{N='host';E={$HostName}},@{N='Cluster';E={$HostCluster}} } } | export-csv c:qSetting.csv
