When deploying the Autonomous REST Connector in a SaaS application, the Composer interface provides a dedicated Diagnostics tab to manage debug recording. The settings on this tab allow you to enable recording and download logs.
Note: For information about deploying the Autonomous REST Connector in
a SaaS application, refer to Branding the Autonomous REST Composer and

Recording and downloading logs
The following settings may be used for recording user sessions and downloading logs:

- Enable Recording: Use this setting to start diagnostic recording of system events, API calls, and error conditions. When enabled, a .rec file containing detailed session logs is written to the server. The .rec file is saved in the TEMP directory and named with a randomly generated ID linked to the user session.
- Download Log File: Use this setting to download logs to your local system. The logs include timestamped events and system details for troubleshooting connection issues, analyzing performance, creating support tickets, and monitoring the system. The original .rec file is converted into individual snapshots and compressed into a ZIP archive. The ZIP file is named after the Model being created.
File management and system properties
The .rec files are managed on the server in the following way:
- The .rec file is encrypted on the server and decrypted only when converted into individual snapshots for download.
- By default, a .rec file records for a maximum duration of 24 hours to
prevent excessive file growth. This limit can be modified using the system
property
DDTEK_RECORDING_FILEAGE_LIMIT. - The default maximum file size is 100 MB, which can be adjusted through the
system property
DDTEK_RECORDING_FILESIZE_LIMIT. - The system property
DDTEK_RECORDING_CLEANUP_AFTER_N_REQUESTSspecifies the maximum number of requests that can be stored before an error occurs. - The .rec files are automatically deleted when the client disconnects. As an additional safeguard, they are also removed after remaining on the server for more than 24 hours.
- All .rec files are stored in the TEMP directory on the server machine.
