+### [ARM Template](#tab/arm-template)
+
+Use the [ARM template](https://learn.microsoft.com/en-us/azure/azure-monitor/resource-manager-samples?tabs=powershell) to create a diagnostic setting .
+
+> [!NOTE]
+> We recommend setting the **logAnalyticsDestinationType** property to **Dedicated** for enabling resource specific tables.
+
+1. Create the following Template file for your ComsosDB resource. 
+
+    ```json
+    {
+	"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
+	"contentVersion": "1.0.0.0",
+	"parameters": {
+		"settingName": {

+		}
+	}]
+    }
+
+    ```
+
+1. Create the following Parameter file for your CosmosDB resource. 
+
+    ```json
+    {

+			},
+			"logAnalyticsDestinationType":{
+				"value": "Dedicated"
+			}
+        }
+    }
+    ```
+
+
+1. Deploy the template by using any [deployment method for Resource Manager templates](https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/deploy-portal).
