* Logs collection from [Azure Monitor](https://docs.microsoft.com/en-us/azure/monitoring-and-diagnostics/monitoring-get-started) using our [Azure Event Hubs source](/docs/send-data/collect-from-other-data-sources/azure-monitoring/ms-azure-event-hubs-source/).
* Activity Logs collection from [Azure Monitor](https://docs.microsoft.com/en-us/azure/monitoring-and-diagnostics/monitoring-get-started) using our [Azure Event Hubs source](/docs/send-data/collect-from-other-data-sources/azure-monitoring/ms-azure-event-hubs-source/). It is recommended to create a separate source for activity logs. If you are already collecting these logs, you can skip this step.
* Metrics collection using our [HTTP Logs and Metrics source](/docs/send-data/collect-from-other-data-sources/azure-monitoring/collect-metrics-azure-monitor/) via Azure Functions deployed using the ARM template.
* Metrics collection using our [Azure Metrics Source](/docs/send-data/hosted-collectors/microsoft-source/azure-metrics-source).

You must explicitly enable diagnostic settings for each storage service (blob, queue, table, and file) and each storage account that you want to monitor. You can forward logs to the same event hub provided they satisfy the limitations and permissions as described [here](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/diagnostic-settings?tabs=portal#destination-limitations).

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/Storage/Logs`, `Azure/Storage/Metrics`.

### Configure field in field schema
1. [**Classic UI**](/docs/get-started/sumo-logic-ui-classic). In the main Sumo Logic menu, select **Manage Data > Logs > Fields**. <br/>[**New UI**](/docs/get-started/sumo-logic-ui). 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 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).
- `service_type`. Type of the service that can be accessed from with an Azure resource (for example, blobservices).
- `service_name`. Services that can be accessed from within an Azure resource (for example, Azure SQL databases in Azure SQL Server).


3. Create the fields if it is not present. Refer to [create and manage fields](/docs/manage/fields/#manage-fields).

### Configure Field Extraction Rules

Create a Field Extraction Rule (FER) for Azure Storage by following the instructions [here](/docs/manage/field-extractions/create-field-extraction-rule/).

* **Azure Location Extraction FER**

```sql
Rule Name: AzureLocationExtractionFER
Applied at: Ingest Time
Scope (Specific Data): tenant_name=*
```

```sql title="Parse Expression"
json "location", "properties.resourceLocation", "properties.region" as location, resourceLocation, service_region nodrop
| replace(toLowerCase(resourceLocation), " ", "") as resourceLocation
| if (!isBlank(resourceLocation), resourceLocation, location) as location
| if (!isBlank(service_region), service_region, location) as location
| if (isBlank(location), "global", location) as location
| fields location
```

* **Resource ID Extraction FER**

```sql
Rule Name: AzureResourceIdExtractionFER
Applied at: Ingest Time
Scope (Specific Data): tenant_name=*
```

```sql title="Parse Expression"
json "resourceId", "ResourceId" as resourceId1, resourceId2 nodrop
| if (isBlank(resourceId1), resourceId2, resourceId1) as resourceId
| toUpperCase(resourceId) as resourceId
| parse regex field=resourceId "/SUBSCRIPTIONS/(?<subscription_id>[^/]+)" nodrop
| parse field=resourceId "/RESOURCEGROUPS/*/" as resource_group nodrop
| parse regex field=resourceId "/PROVIDERS/(?<provider_name>[^/]+)" nodrop
| parse regex field=resourceId "/PROVIDERS/[^/]+(?:/LOCATIONS/[^/]+)?/(?<resource_type>[^/]+)/(?<resource_name>.+)" nodrop
| parse regex field=resource_name "(?<parent_resource_name>[^/]+)(?:/PROVIDERS/[^/]+)?/(?<service_type>[^/]+)/?(?<service_name>.+)" nodrop
| if (isBlank(parent_resource_name), resource_name, parent_resource_name) as resource_name
| fields subscription_id, location, provider_name, resource_group, resource_type, resource_name, service_type, service_name
```
### Configure metric rules

* **Azure Observability Metadata Extraction Service Level**

In case this rule is already exists then no need to create again.
```sql
Rule Name: AzureObservabilityMetadataExtractionServiceLevel
```

```sql title="Metric match expression"
resourceId=/SUBSCRIPTIONS/*/RESOURCEGROUPS/*/PROVIDERS/*/*/*/*/* tenant_name=*
```
| Fields extracted | Metric rule |
|------------------|----------------|
| subscription_id | $resourceId._1 |
| resource_group | $resourceId._2 |
| provider_name | $resourceId._3 |
| resource_type | $resourceId._4 |
| resource_name | $resourceId._5 |
| service_type | $resourceId._6 |
| service_name | $resourceId._7 |

* **Azure Observability Metadata Extraction Storage Account Level**
```sql
Rule Name: AzureObservabilityMetadataExtractionStorageAccountLevel
```

```sql title="Metric match expression"
resourceId=*/SUBSCRIPTIONS/*/RESOURCEGROUPS/*/PROVIDERS/*/*/* tenant_name=* accountresourceid=*
```
| Fields extracted | Metric rule |
|------------------|----------------|
| subscription_id | $resourceId._1 |
| resource_group | $resourceId._2 |
| provider_name | $resourceId._3 |
| resource_type | $resourceId._4 |
| resource_name | $resourceId._5 |

### 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.

1. Create a hosted collector and tag the `tenant_name` field
<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 `Transaction`.
* 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.
<img src={useBaseUrl('img/integrations/microsoft-azure/Azure-Storage-Tag-Location.png')} alt="Azure Storage Tag Location" style={{border: '1px solid gray'}} width="500" />
To set up the Azure Metrics source in Sumo Logic, refer to [Azure Metrics Source](/docs/send-data/hosted-collectors/microsoft-source/azure-metrics-source).

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