GET Storage Usage request

PDFs
The GET Storage Usage request tells you the total amount of storage in use by an account, and for each bucket associated with the account.
The amount of storage used by an account and its buckets can be obtained by a modified ListBuckets request with the x-ntap-sg-usage query parameter. Bucket storage usage is tracked separately from the PUT and DELETE requests processed by the system. There might be some delay before the usage values match the expected values based on the processing of requests, particularly if the system is under heavy load.
By default, StorageGRID attempts to retrieve usage information using strong-global consistency. If strong-global consistency can't be achieved, StorageGRID attempts to retrieve the usage information at a strong-site consistency.
You must have the s3:ListAllMyBuckets permission, or be account root, to complete this operation.
