DataService Studio provides log analysis for reviewing API requests. When a request fails, intelligent analysis helps you quickly identify the root cause and provides a diagnosis with actionable suggestions.
Limits
The intelligent analysis feature is available only in DataWorks Professional Edition or later. You can try this feature for free, but we recommend that you upgrade to the Professional Edition to access more product capabilities. For more information about edition upgrades, see DataWorks editions.
