As of 19 November 2017, Wasabi has started providing per-bucket usage statistics. This info is initially available as .csv file for each bucket and is accessible under the Settings page for each bucket. In a future release, Wasabi will incorporate this data into the info set provided under the Billing page for each account.
When the .csv file is downloaded for a bucket, you will see information that looks like the example below. Each row of the table represents a 24 hour period. For new buckets, it will take up to 24 hours for the .csv option to show up (a billing cycle that runs every 24 hours needs to be completed at least once for the .csv file to be available).
Note that the 'Bucket Size' info displayed on the Wasabi UI represents the raw file size values for all of the files in the bucket. This number will be slightly lower than the BillableActiveStorageBytes number in the .csv file because the BillableActiveStorageBytes number includes the metadata associated with the files.
It is also important to note that the Bucket Size info on the Wasabi UI does not factor in any deleted storage values that may show up in the .csv file.
The definition of each column header is as follows:
Bucket: the bucket name
BucketNum: the system-wide internal bucket number
StartTime: the start of the measurement period (in UTC time)
EndTime: the end of the measurement period (in UTC time)
NumBillableActiveStorageObjects: the number of objects in the bucket that are considered to be Active Storage
NumBillableDeletedStorageObjects: the number of objects in the bucket that are considered to be DeletedStorage (i.e. storage that has not yet met the 90 day minimum storage period)
BillableActiveStorageBytes: the total number of storage bytes & associated metadata consumed by all Active Storage objects in the bucket
BillableDeletedStorageBytes: the total number of storage bytes & associated metadata consumed by all Deleted Storage objects in the bucket
NumAPICalls: the number of API calls against the bucket
IngressBytes: the number of ingress (upload) bytes against the bucket
EgressBytes: the number of egress (download) bytes against the bucket
