Since there is no information available from the "radosgw-admin bucket stats" commands nor any other endpoint I tried to browse the source code but couldn't find any references where the storage class would be exposed in such a way. It also seems that RadosGW today is not saving any counters on amount of objects stored in storage classes when it's collecting usage stats, which means there is no such metadata saved for a bucket. I was hoping it was atleast saved but not exposed because then it would have been a easier fix than adding support to count number of objects in storage classes based on operations which would involve a lot of places and mean writing to the bucket metadata on each op :( Is my assumptions correct that there is no way to retrieve such information, meaning there is no way to measure such usage? If the answer is yes, I assume the only way to get something that could be measured would be to instead have multiple placement targets since that is exposed from in bucket info. The bad things would be though that you lose a lot of functionality related to lifecycle and moving a single object to another storage class.
