Are you missing that information? https://github.com/ceph/ceph/blob/master/src/rgw/rgw_user.cc#L413

  op_type_to_str(info.op_mask, buf, sizeof(buf));
  encode_json("op_mask", (const char *)buf, f);
  encode_json("system", (bool)info.system, f);
  encode_json("admin", (bool)info.admin, f);
  encode_json("default_placement", info.default_placement.name, f);
  encode_json("default_storage_class", info.default_placement.storage_class, f);
  encode_json("placement_tags", info.placement_tags, f);
  encode_json("bucket_quota", info.bucket_quota, f);
  encode_json("user_quota", info.user_quota, f);
  encode_json("temp_url_keys", info.temp_url_keys, f);

I'm wondering because that information is returned by the Admin OPS API, see https://github.com/ceph/ceph/blob/master/src/rgw/rgw_rest_user.cc#L91.

I'm wondering because that information is returned by the Admin OPS API, see https://github.com/ceph/ceph/blob/master/src/rgw/rgw_rest_user.cc#L91.

The user_quota contains
"user_quota": {
"enabled": false,
"check_on_raw": false,
"max_size": -1,
"max_size_kb": 0,
"max_objects": -1
}
which is not enough information to calculate the usage.
Additional information required: {
"stats": {
"size": 0,
"size_actual": 0,
"size_utilized": 0,
"size_kb": 0,
"size_kb_actual": 0,
"size_kb_utilized": 0,
"num_objects": 0
}
which we get from CLI using "radosgw-admin user stats --uid=<uid>" command, which I don't think Admin OPS API is returning (atleast not for rgw-user)

Upon further investigation: The RGW-users usage info is not exposed in RGW Admin ops API. I can see CLI command for user stats `radosgw-admin user stats --uid=<uid>` , but this isn't exposed in any of existing RGW-users API or as a seperate endpoint. Also I tried

$ curl -kX GET "https://localhost:11000/api/rgw/user?stats=true" -H  "accept: application/vnd.ceph.api.v1.0+json" -H  "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJjZXBoLWRhc2hib2FyZCIsImp0aSI6IjcxMzViZGU1LTk1Y2MtNDcyMC1hNTAxLWQzY2E5NDNiZTU2YiIsImV4cCI6MTYxNDc4Mjg1OSwiaWF0IjoxNjE0NzU0MDU5LCJ1c2VybmFtZSI6ImFkbWluIn0.WTwnXFvcmssar-nwhtfDHdE4ES5nn8SLXuGSZdQYUjg" 

{"status": "500 Internal Server Error", "detail": "The server encountered an unexpected condition which prevented it from fulfilling the request.", "request_id": "662e60ad-6f87-4486-8c15-5d990fe53a00"}

But it seems like this only works for buckets but not users. So I think maybe RGw team needs to expose this as a API.
Required payload for API: https://tracker.ceph.com/issues/45965#note-4
Or am I missing something here? @Casey Bodley thoughts?

the radosgw /admin/user api supports a ?stats param for this

Also I saw that apart from the one that Casey pointed out:
GET /admin/user?stats=true&uid=<user-id>

It seems this endpoints also provides needed info:
GET /admin/metadata/user?key=<user-id>
