10. How does Nodinite extract business data from SOAP faults and exceptions?

Part of the WCF Diagnostics Tracing troubleshooting and FAQ guide.

WCF Diagnostics Tracing emits SOAP fault details in trace events (fault code, fault string, fault detail XML). Nodinite stores complete fault payloads. Search Field Expression with XPath can extract exception data: //faultstring (error message), //detail/ExceptionType (exception class name), //detail/StackTrace (call stack), //detail/InnerException/Message (root cause). Example: Extract SQL Server constraint violation from SOAP fault //detail/SqlException/Number (2627 = duplicate key) → Search Field "SQL Error Code" → Log View filter "Show all duplicate key violations last 7 days" → Export for database schema review.
