 When you configure the event hubs source or HTTP source, plan your source category to ease the querying process. A hierarchical approach allows you to make use of wildcards. For example: `Azure/VirtualNetwork/Metrics` and `Azure/VirtualNetwork/Logs`.

In the top menu select **Configuration**, and then under **Logs** select **Fields**. You can also click the **Go To...** menu at the top of the screen and select **Fields**.
-1. Search for the following fields:
-   - `tenant_name`. This field is tagged at the collector level and users can get the tenant name using the instructions [here](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tenant-management-read-tenant-name#get-your-tenant-name).
-   - `location`. The region to which the resource name belongs.
-   - `subscription_id`. Id associated with a subscription where the resource is present.
-   - `resource_group`. The resource group name where the Azure resource is present.
-   - `provider_name`. Azure resource provider name (for example, Microsoft.Storage).
-   - `resource_type`. Azure resource type (for example, storageaccounts).
-   - `resource_name`. The name of the resource (for example, storage account name).

 ### Configure metrics collection
 
-In this section, you will configure a pipeline for shipping metrics from Azure Monitor to an Event Hub, onto an Azure Function, and finally to an HTTP Source on a hosted collector in Sumo Logic. This step is required only for DDOS related metrics which comes after enabling DDOS protection in your virtual network.
+import MetricsSourceBeta from '../../reuse/metrics-source-beta.md';
 
-1. Create a hosted collector and tag `tenant_name` field. <br/><img src={useBaseUrl('img/integrations/microsoft-azure/Azure-Storage-Tag-Tenant-Name.png')} alt="Azure Storage Tag Tenant Name" style={{border: '1px solid gray'}} width="800" />
-2. [Configure an HTTP Source](/docs/send-data/collect-from-other-data-sources/azure-monitoring/collect-metrics-azure-monitor/#step-1-configure-an-http-source).
-1. [Configure and deploy the ARM Template](/docs/send-data/collect-from-other-data-sources/azure-monitoring/collect-metrics-azure-monitor/#step-2-configure-azure-resources-using-arm-template).
-1. [Export metrics to Event Hub](/docs/send-data/collect-from-other-data-sources/azure-monitoring/collect-metrics-azure-monitor/#step-3-export-metrics-for-a-particular-resource-to-event-hub). Perform the steps below for each storage service (blob, queue, table, and file) and each storage account that you want to monitor.
-   * Choose `Stream to an event hub` as the destination.
-   * Select `AllMetrics`.
-   * Use the Event hub namespace created by the ARM template in Step 2 above. You can create a new Event hub or use the one created by the ARM template. You can use the default policy `RootManageSharedAccessKey` as the policy name.
-4. Tag the location field in the source with the right location value.<br/><img src={useBaseUrl('img/integrations/microsoft-azure/Azure-Storage-Tag-Location.png')} alt="Azure Storage Tag Location" style={{border: '1px solid gray'}} width="500" />
-5. Enable the `DDOS protection` by following the instructions in Azure [documentation](https://learn.microsoft.com/en-us/azure/ddos-protection/manage-ddos-protection#enable-for-an-existing-virtual-network)

+As part of the app installation process, the following fields will be created by default:

+- `tenant_name`. This field is tagged at the collector level. You can get the tenant name using the instructions [here](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tenant-management-read-tenant-name#get-your-tenant-name).

+- `resource_group`. The resource group name where the Azure resource is present.
+- `provider_name`. Azure resource provider name (for example, Microsoft.Network).
+- `resource_type`. Azure resource type (for example, storage accounts).
+- `resource_name`. The name of the resource (for example, storage account name).
+- `service_type`. Type of the service that can be accessed with an Azure resource.
+- `service_name`. Services that can be accessed with an Azure resource (for example, in Azure Container Instances the service is Subscriptions).
+
+Also FER `AzureVirtualNetworkTargetResourceIdExtractionFER` will be created as part of the app installation process itself.
