Creating a Tracker

Function

When you enable CTS, a tracker is automatically created to associate with the cloud services you are using and record all operations on the services. Currently, only one management tracker can be created for a cloud account in a region. Traces are retained in the CTS console for seven days. For long-term storage, you can enable Object Storage Service (OBS) and deliver real-time operation records to OBS buckets.
