--- title: Monitor the capacity of an Azure NetApp Files volume description: Describes ways to monitor the capacity utilization of an Azure NetApp Files volume. services: azure-netapp-files author: b-hchen ms.service: azure-netapp-files ms.topic: how-to ms.date: 09/04/2024 ms.author: anfdocs ms.custom: - devx-track-azurecli - linux-related-content - sfi-image-nochange # Customer intent: As a system administrator, I want to monitor the capacity utilization of Azure NetApp Files volumes, so that I can ensure efficient storage management and prevent capacity issues. --- # Monitor the capacity of a volume This article describes ways to monitor the capacity utilization of an Azure NetApp Files volume. ## Using Windows or Linux clients This section shows how to use a Windows or Linux client to monitor the volume capacity. The scenarios described in this section assume a volume configured at 1 TiB size (quota) on a 4 TiB Ultra service-level capacity pool. ### Windows (SMB) clients You can use Windows clients to check the used and available capacity of a volume through the network mapped drive properties. You can use one of the following two methods: * Navigate to File Explorer, right-click the mapped drive, then select **Properties** to display capacity. [  ](./media/monitor-volume-capacity/monitor-explorer-drive-properties.png#lightbox) * Use the `dir` command at the command prompt:  The *available space* is accurate using File Explorer or the `dir` command. However, the *consumed/used space* will be an estimate when snapshots are generated on the volume. The [consumed snapshot capacity](azure-netapp-files-cost-model.md#capacity-consumption-of-snapshots) counts towards the total consumed space on the volume. To get the absolute volume consumption, including the capacity used by snapshots, use the [Azure NetApp Metrics](azure-netapp-files-metrics.md#volumes) in the Azure portal. ### Linux (NFS) clients Linux clients can check the used and available capacity of a volume using the [`df -h`](https://linux.die.net/man/1/df). Using the `h` option displays the size, including used and available space in human readable format (using M, G and T unit sizes). The following snapshot shows volume capacity reporting in Linux:  The *available space* is accurate using the `df` command. However, the *consumed/used space* will be an estimate when snapshots are generated on the volume. The [consumed snapshot capacity](azure-netapp-files-cost-model.md#capacity-consumption-of-snapshots) counts towards the total consumed space on the volume. To get the absolute volume consumption, including the capacity used by snapshots, use the [Azure NetApp Metrics](azure-netapp-files-metrics.md#volumes) in the Azure portal. > [!NOTE] > The `du` command doesn’t account for the space used by snapshots generated in the volume. As such, it’s not recommended for determining the available capacity in a volume. ## Using Azure portal Azure NetApp Files leverages the standard [Azure Monitor](/azure/azure-monitor/overview) functionality. As such, you can use Azure Monitor to monitor Azure NetApp Files volumes. ## Using Azure CLI You can use the [`az netappfiles volume`](/cli/azure/netappfiles/volume) commands of the [Azure command line (CLI) tools](azure-netapp-files-sdk-cli.md) to monitor a volume. ## Using REST API See [REST API for Azure NetApp Files](azure-netapp-files-develop-with-rest-api.md) and [REST API using PowerShell for Azure NetApp Files](develop-rest-api-powershell.md). The REST API specification and example code for Azure NetApp Files are available through the [resource-manager GitHub directory](https://github.com/Azure/azure-rest-api-specs/tree/main/specification/netapp/resource-manager/Microsoft.NetApp/stable). ## Next steps * [Understand volume quota](volume-quota-introduction.md) * [Cost model for Azure NetApp Files](azure-netapp-files-cost-model.md) * [Resize the capacity pool or a volume](azure-netapp-files-resize-capacity-pools-or-volumes.md) * [Capacity management FAQs](faq-capacity-management.md)
