Operation Scenarios

AS can use the Cloud Trace Service (CTS) to record resource operations. CTS can record operations performed on the management Console after login using a cloud platform account, operations performed by calling APIs through cloud services, and operations triggered within the cloud system. If you have activated CTS, when a call is made to the AS API, the operation will be reported to CTS which will then deliver the operation record to a specified OBS bucket specified by users for storage. With CTS, you can record operations associated with AS for later query, audit, and backtrack operations. After you enable CTS in the application system, AS records the API calling operations performed on AS resources in log files. On the CTS Console, you can query operation records for the last 7 days. To get more operation records, you can enable the Object Storage Service (OSS) and synchronize operation records to the OSS in real time.

The following table lists the AS operations that can be recorded by CTS.

Operation	Resource type	Event Name

Log Entries

Each CTS log entry consists of an event in JSON format. A log entry indicates an SMN API request, including the requested operation, the operation date and time, operation parameters, and information about the user who sends the request. The user information is obtained from the identity and access management service.

The following example shows CloudTrace log entries for the CreateScalingPolicy action:
