Using Tracing APIs

Use these APIs to enable the application user to use End-to-End tracing.

The API consists of the following interfaces or classes:

• SUPE2ETraceService – A public interface for use by the application's user interface developers.

• SUPE2ETraceLevel – Defines an enumeration of the trace levels that you can set to a passport. Trace levels control the amount of logging done on the server side. 

• SUPE2ETraceServiceImpl – The implementation of the SUPE2EtraceService interface; the implementation is a singleton. There are additional methods for you to create a passport and business transaction. 

• SUPE2ETraceMessage – An entity class which holds the request/response details and statistics and the passport. Object API internally makes use of this class to add request/response details to the business transaction and to get a new passport for each new request. Object API sets the new passport to the HTTP header, 'SAP-PASSPORT' and sends it to the server side, so that the server can continue processing the E2E tracing.

• Getting an Instance of the E2E Trace Service
