Logging Overview

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

OBS allows you to configure access logging for buckets. After the configuration, access to buckets will be recorded in the format of logs. These logs will be saved in specific buckets in OBS.

You can enable OBS logging for bucket analysis or audit purposes. With access logs, a bucket owner can analyze the sources, types, or trends of requests sent to the bucket.

With logging enabled, OBS automatically logs access requests for the bucket and writes the generated log files into a specified bucket.

Log files can be stored in any bucket you own in the region where the logged bucket is, including the logged bucket itself.

For more information, see Logging.
