Configure logging

Last updated:2021-10-18 16:00:49

You can enable and disable logging for buckets in the Kingsoft Cloud Standard Storage Service (KS3) console. You can store the logs of a bucket in the same bucket itself or create a bucket in the same region to store the logs.

By default, logging is disabled for buckets in KS3. You can enable logging for a bucket and manually specify the storage location.

A log file is named in the format of ks3log_Bucket name_yyyy_MM_dd.log.

For more information about the API operation for configuring logging, see GET Bucket logging.
