Currently a typical log entry looks like this:

2017-05-12 11:59:20.322942 7f5974ff9700  1 civetweb: 0x7f59fc0014d0: 10.80.0.6 - - [12/May/2017:11:59:20 +0000] "GET / HTTP/1.1" 200 0 - -

There are multiple issues with this:

1. The response size (the number after the "200" status code) is always show as 0, even if data is returned to the client.
2. There is no indication about the "Host" header, so one cannot tell whether this is a list_bucket or a list_buckets request. For the former, it would also be interesting to know which bucket is being targeted, similar for object operations.
3. The user id or name is not shown.
4. As an additional bonus, it would also be nice to should the time it took to serve this request.

Some of this information can be collected from other log entries if one increases the log level, but on a high volume site serving hundreds of requests per second, this is impractical. One can compute the answer to 4. from the req start/done log entries that are included in the default logging, but it still would require some post-processing to take place.
