Managing Tags

Tag Management

A tag is a user-defined key-value pair used to identify cloud resources, helping you classify and search for them. A tag consists of a tag key and a tag value.

If you use tags in other cloud services, you are advised to create the same tag (key-value pairs) for cloud resources used by the same business to keep consistency.

DLI supports the following two types of tags:

• Resource tags: non-global tags created on DLI

• Predefined tags: global tags created on Tag Management Service (TMS).

  For details about predefined tags, see Tag Management Service User Guide.

DLI allows you to add, modify, or delete tags for queues.

1. In the left navigation pane of the DLI console, choose Resources > Resource Pool.
2. In the Operation column of the queue, choose More > Tags.
3. The tag management page is displayed, showing the tag information about the current queue.
4. On the page that appears, click Add/Edit Tag in the upper left corner. Enter a tag and a value, and click Add.
