Cloud Trace Service

Cloud Trace Service (CTS) records operations on cloud resources in your account. You can use the logs to perform security analysis, track resource changes, audit compliance, and locate faults.

After you enable CTS and configure a tracker, CTS can record management and data traces of OBS for auditing.

Follow-up Procedure

You can click Disable under the Operation column on the right of a tracker to disable the tracker. After the tracker is disabled, the system will stop recording operations, but you can still view existing operation records.

You can click Delete under the Operation column on the right of a tracker to delete the tracker. Deleting a tracker has no impact on existing operation records. When you enable CTS again, you can view operation records that have been generated.
