Configure logging

You can enable and disable logging for buckets in the KS3 console. You can store logs in an existing bucket with logging enabled or create a bucket in the same region to store logs.

Logging in KS3 is disabled by default. You can enable it and set the storage location manually.

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


  1. Log in to the KS3 console and click Bucket in the left navigation pane. On the Bucket list page, click the name of the target bucket. On the page that appears, click Bucket Settings. On the Basic settings tab, click Edit for Log status settings.

  2. Select Open, set the Log Storage Location parameter, and then click Save. Logs are stored in the current bucket by default. You can also select a bucket in the same region to store logs.
