 ## Map an existing field to the service name field

+For logs that already have the field to use as the service name, map that field to the `service.name` field using the [alias field type](((ref))/field-alias.html).
 Follow these steps to update your mapping:
 
-1. Find the field you want to map to the `service.name` field. For this example, we'll use `my_service`.
-1. Update your index mapping to map `my_service` to `service.name` by adding an alias:
-
-        ```Console
-        PUT your_index/_mapping
-        {
-        "properties": {
-            "@timestamp": {
-              "type": "date"
-            },
-            "your_service_field": {
-              "type": "keyword"
-            },
-            "service.name": {
-              "type": "alias",
-              "path": "your_service_field"
-            }
-        }
-        }
-        ```
-
-1. Verify that the index mapping is showing the `service.name` field with the following command:
-
-        ```console
-        GET your_index/_search
-        ```
-
-For more on using an alias, refer to [alias field type](((ref))/field-alias.html).
+1. Go to **Management** → **Index Management** → **Index Templates**.
+1. Search for the index template you want to update.
+1. From the **Actions** menu for that template, select **edit**.
+1. Got to **Mappings**, and select **Add field**.
+1. Under **Field type**, select **Alias** and add `service.name` to the **Field name**.
+1. Under **Field path**, select the existing field you want to map to the service name.
+1. Select **Add field**.
