Managing Tags

Tag Management

A tag is a key-value pair that you can customize to identify cloud resources. It helps you to classify and search for cloud resources. 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

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. Click Add/Edit Tag. The Add/Edit Tag dialog is displayed. Enter a tag and a value, and click Add.
