 For Azure Cache for Redis, you can collect the following logs and metrics:
 
 * **Connection logs**. These logs contains information about the connections to the cache for security and diagnostic purposes. To learn more about the [limitations of connection logging](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-monitor-diagnostic-settings?tabs=basic-standard-premium#prerequisiteslimitations-of-connection-logging) and [schemas](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-monitor-diagnostic-settings?tabs=basic-standard-premium#contents-of-the-connection-logs) collected for Azure Cache for Redis, refer to the Azure documentation.
+* **Activity logs**, provides insight into any subscription-level or management group level events that have occurred in the Azure. To learn more, refer to [Azure documentation](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/activity-log-schema).
 * **Cache Metrics**. These metrics are available in [Microsoft.Cache/redis](https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-cache-redis-metrics) and [Microsoft.Cache/redisEnterprise](https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-cache-redisenterprise-metrics) namespace. For more information on supported metrics, refer to the [Azure documentation](https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-how-to-monitor#list-of-metrics).
 
 ## Setup
 
 Azure service sends monitoring data to Azure Monitor, which can then [stream data to Eventhub](https://learn.microsoft.com/en-us/azure/azure-monitor/essentials/stream-monitoring-data-event-hubs). Sumo Logic supports:
 
 * 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.
 
 You must explicitly enable diagnostic settings for each Azure Cache for Redis 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/RedisCache/Logs`, `Azure/RedisCache/Metrics`.

+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 the following fields:
+   - `tenant_name`. This field is tagged at the collector level. You can get the tenant name using the instructions in the [Microsoft Documentation](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 to.
+   - `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.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 a Azure resource.
+   - `service_name`. Services that can be accessed with an Azure resource (for example, Azure SQL databases in Azure SQL Server).
+1. Create the fields if they are not present. Refer to [Manage fields](/docs/manage/fields/#manage-fields).
+
