  3. In the left-side navigation pane, click Instance Monitoring. Find the database instance.
  4. Choose Performance > Storage Analysis in the Actions column.
  5. On the Storage Analysis page, you can view the storage space details. The details include the average daily increase in last week, the available days of storage space, and the total consumed storage space.
  6. You can also view the consumed storage space, the compression percentage, and the index storage space of each collection. To view the indexes of a collection, click the name of the collection.

Global storage usage

Note The Global Storage Usage page cannot display information of database instances deployed in the direct access and centralized-mode access methods, because their storage data cannot be collected.
