Access logs enable a bucket owner to analyze the property, type, or trend of requests to the bucket in depth. Therefore, you can enable logging to facilitate later analysis or audit as required. When the logging function of a bucket is enabled, OBS will log access requests for the bucket automatically, and write the generated log files to the specified bucket (target bucket).

The logging function itself is offered for free, only the space occupied by log files is charged.


After Logging is enabled, the bucket write permission, as well as the ACL read permission will be enabled automatically for log delivery users of the Target Bucket. If you manually disable such permissions, bucket logging fails.
