Tableau Server can record performance metrics for workbooks to troubleshoot slow-loading views. This feature must be enabled at the site level (viaSettings > General > Allow Performance Recording). Once enabled, you can trigger recording for a specific view by modifying its URL.
The correct syntax is to append :record_performance=yes& to the view URL, immediatelyafter the session ID
. For example:
* Original
URL: http://server/#/site/my-site/views/workbook/view?:iid=1
* Modified
URL: http://server/#/site/my-site/views/workbook/view?:iid=1:record_performance=yes
&
After loading the view with this parameter, a performance recording is generated and accessible via the Performanceoption in the toolbar.
* Option B (Type :record_performance=yes& at the end of the view URL, immediately after the session ID): Correct. This follows Tableau's documented method for enabling performance recording.
* Option A (Click the Performance link in the toolbar): Incorrect. The Performance link appears only after recording is triggered via the URL; it's not the method to enable it.
* Option C (Type :record_performance=yes& immediately before the session ID): Incorrect. The parameter must follow the session ID (e.g., :iid=1) to function correctly.
* Option D (Delete the session ID in the URL and reload the view): Incorrect. The session ID is required for the view to load properly; removing it breaks the URL.
