Recording AS Resource Operations
Scenarios
AS can use the Cloud Trace Service (CTS) to record resource operations. CTS can record operations performed on the management console, operations performed by calling APIs, and operations triggered within the cloud system.
If you have enabled 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 for storage. With CTS, you can record operations associated with AS for later query, audit, and backtrack operations.
Obtaining AS Information in CTS
After you enable CTS in the application system, the system logs the API calling operations performed on AS resources. On the Cloud Trace Service console, you can view operation records for the last 7 days. To obtain more operation records, you can enable the Object Storage Service (OBS) and synchronize operation records to the OBS in real time.

Viewing Audit Logs
- Log in to the management console.
- Click
in the upper left corner to select a region and a project.
- Click Service List. Choose Management & Deployment > Cloud Trace Service.
- Click Trace List in the navigation pane on the left.
- You can use filters to query traces. The following filters are available:
- Trace Source, Resource Type, and Search By
Select a filter criterion from the drop-down list.
When you select Trace name for Search By, you need to select a specific trace name.
When you select Resource ID for Search By, you need to select or enter a specific resource ID.
When you select Resource name for Search By, you need to select or enter a specific resource name.
- Operator: Select a specific operator (at user level rather than tenant level).
- Trace Status: Available options include All trace statuses, normal, warning, and incident. You can only select one of them.
- Time range: In the upper right corner of the page, you can query traces in the last one hour, last one day, last one week, or within a customized period of time.
- Trace Source, Resource Type, and Search By
- Click
to the left of the required trace to expand its details.
- Locate the required trace and click View Trace in the Operation column. A dialog box is displayed, showing the trace content.
CTS Log Entries
Each log entry consists of a trace in JSON format. A log entry indicates an AS 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 (IAM) service.
