Hello,
is there an option to see the used and free capacity of every VM size or series in each region and zone to avoid allocation fails?
thank you
hello @Anonymous ,
I don't mean the Quota limits but the used and free capacity of an Azure region. Because I had too often the issue that a VM could not start (allocation failed) despite of available quota.
thank you

Hello, @Mares Martin !
(Edit) Apologies, the previous answer was in the context of another thread. I'm looking into this and will give you an update as I learn more.
Hello, @Mares Martin !
I've been reviewing this some more and az vm list-skus is going to be your best resource for seeing what is available. There's no public documentation or API that will give you a list of datacenter resources (ex: 870 out of 1000 NV48as_v4 in use in West US), but this will give you a snapshot of what VMs are available to your subscription in a given region.
If you do run into a scenario where you have quota available but are unable to create a resource (there have been a couple reports of this in high demand regions) then the proper path to secure those resources is to create a support request as outlined in the sticky (making a note in the details section of the SKU, core count, and region you are interested in).
I've been reaching out to the VM product group frequently to get more information and will update the sticky as I learn more.
Hello, @Mares Martin !
How do I see what amount of my virtual machine quota I've used?
In addition to the portal, you can use Azure CLI or PowerShell to check your current quota usage and availability.
https://learn.microsoft.com/en-us/azure/virtual-machines/linux/quotas
https://learn.microsoft.com/en-us/azure/virtual-machines/windows/quotas
Azure CLI
List VM usage for a region:
az vm list-usage --location "East US" -o table
Azure PowerShell
List VM usage for a region:
Get-AzVMUsage -Location "East US"
How do I see what VM size is available prior to deployment?
The NotAvailableForSubscription error indicates that there is no availability in the subscription for that VM size (see the sticky for more information). The documentation has been updated to provide solutions using Azure CLI, PowerShell, and REST (and of course you can always check the portal as well). When viewing the results, look for NotAvailableForSubscription in the Restriction column.
Azure CLI
List specific SKUs for a region (D in this example):
az vm list-skus --location centralus --size Standard_D --all --output table
List all SKUs for a region:
az vm list-skus --location centralus --zone --all --output table
PowerShell
List all SKUs for a region:
Get-AzComputeResourceSku | Where-Object { $_.Locations -contains "centralus" }
Similarly, you can use this which formats a bit better by default for me:
Get-AzComputeResourceSku "centralus";
