We often found free space in a datastore has dramatically reduced. Is there any way we can get the VM name and the amount it contributes to this free space utilization?

Try to find a Script that gives me Cluster Performance values for a “custom Time-Schedule” (CPU MHz usage max/average and Memory consumed max/average) for all Clusters

Great function.

Hi Luc, you´re right, some datastores don´t have HI4 statistics. When I change to HI3 or HI2, all works fine.
But, after a few runs of the script, I see that some VMs don´t show on the list.
And after a time looking, I found that the VMs with disks bigger than 2Tb was the trouble.
I cut the script to look like this (for diagnose purposes):

*-*-*-*

$metrics = “disk.used.latest”
$report = @()
foreach($vm in Get-VM ){
$report += Get-Stat -entity $vm.ExtensionData -stat $metrics -interval “HI2” |
Sort-Object -Property Timestamp |
Group-Object -Property Timestamp | %{
New-Object PSObject -Property @{
“VM Name” = $vm.Name
Timestamp = $_.Name
“Used (GB)” = [Math]::Round(($_.Group |
where {$_.CounterName -eq “disk.used.latest”}).Value/1GB,2)

}
}
}
$report | Export-Csv “z:\DS-stats_sata.csv” -NoTypeInformation -UseCulture

*-*-*-*-*

I think the problem is to handle the numbers, because a VM got a disk of 3Tb and the “disk.used.latest” is under 2Tb. If i cut the “disk.provisioned.latest” line on the original script, the VM is showed on the list.

What do you think about this?

I hope you can understand my idea because my english is too poor.

Thanks in advance.

LucD :
@tequesta,in the code you specify Historical Interval 4 (HI4). That means data from more than 1 month ago with an interval of 1 day.
If the Get-Stat cmdlet doesn’t find any data that corresponds, it will not return anything at all.
Like I said in the other reply, are you sure that there is data for HI4 available for these specific datastores ? You can check by looking under the Performance tab in the vSphere client.
You could also try to get the report for a more recent intervals (HI3, HI2….).
Let me know if that brings something ?

Thanks LucD.

Thats the problem, I have less than 1 month of data of some datastores.

Thank you very much!
