Hi
I am currently working on retrieving user usage and usage logs from Ceph
RGW using Boto3. While I am able to successfully obtain user usage and all
bucket usage with the following model and code:
```python
params = {
"start-date": "2023-05-13T00:00:00Z",
"end-date": "2023-05-13T23:59:59Z",
}
print(json.dumps(s3_client.get_usage_stats(**params), indent=2))
```
```json

```
and this is my output:
```
"Summary": {
"QuotaMaxBytes": -1,
"QuotaMaxBuckets": 1000,
"QuotaMaxObjCount": -1,
"QuotaMaxBytesPerBucket": -1,
"QuotaMaxObjCountPerBucket": -1,
"TotalBytes": 52696,
"TotalBytesRounded": 53248,
"TotalEntries": 1
},
"CapacityUsed": {
"User": {
"Buckets": {
"Entry": [
{
"Bucket": "opa-test",
"Bytes_Rounded": 53248,
"Bytes": 52696
},
{
"Bucket": "ramfrom",
"Bytes_Rounded": 0,
"Bytes": 0
}
}
}
}
}
```
The issue I am facing is that the usage logs are not being displayed. Upon
investigating the code in the send_response() function of the
RGWGetUsage_ObjStore_S3 class, I found the following conditions:
```cpp
if (show_log_sum) {
formatter->open_array_section("Summary");
map<string, rgw_usage_log_entry>::iterator siter;
for (siter = summary_map.begin(); siter != summary_map.end(); ++siter) {
const rgw_usage_log_entry& entry = siter->second;
formatter->open_object_section("User");
formatter->dump_string("User", siter->first);
dump_usage_categories_info(formatter, entry, &categories);
rgw_usage_data total_usage;
entry.sum(total_usage, categories);
formatter->open_object_section("Total");
encode_json("BytesSent", total_usage.bytes_sent, formatter);
encode_json("BytesReceived", total_usage.bytes_received, formatter);
encode_json("Ops", total_usage.ops, formatter);
encode_json("SuccessfulOps", total_usage.successful_ops, formatter);
formatter->close_section(); // total
formatter->close_section(); // user
}
```
According to the code, the show_log_sum parameter must be true to display
the summary log entries, and I have confirmed that it is indeed set to true.
Additionally, the show_log_entries parameter must also be true to retrieve
the usage log entries, and I have verified that it is set to true as well.
I am using Ceph version 16.2.12, and I have set the RGW debug level to 99.
Here is a snippet of the log output:

I would greatly appreciate any guidance or insights into why I am unable to
retrieve the usage logs. How can I ensure that the usage logs are included
in the response?
Thank you for your assistance!
P.S.
I have also verified the response using tools like Wireshark and tcpdump,
and I can confirm that the responses received are consistent with the
output I provided earlier.
