Last Updated:Jun 04, 2026

Add tags to Object Storage Service (OSS) buckets to track per-bucket costs on the Split Bill page in the Expenses and Costs console. For example, tag buckets by department to view each department's costs separately.

  2. In the left-side navigation pane, click Buckets. On the Buckets page, find and click the desired bucket.

  3. In the left-side navigation pane, choose Bucket Settings > Bucket Tagging.

  4. On the Bucket Tagging page, click Create Tag.

  5. Click + Tag, and then enter a key and value for the tag or select an existing tag.

    To add multiple tags, click + Tag.

  6. Click Save.

The tag appears on the cost allocation tags page one day after you add it.

Enable a cost allocation tag before it appears in your split bills.

  1. Go to the Expenses and Costs Cost allocation tags page and enable the cost allocation tag feature if prompted.

  2. On the Cost Allocation Tag page, enable the cost allocation tag.

    In the Tag Key search box, enter the tag key, such as department, and click Search. Find the tag and click Enable in the Actions column.

Step 3: View costs in split bills

  1. Go to the Expenses and Costs Split Bill page and enable the Split Bill feature if prompted.

  2. In the Service column, select Object Storage Service (OSS). Set other filter conditions as needed.
