EMA C++ Developers Guide : 6 Consuming Data from the Cloud : 6.10 Logging of Authentication and Service Discovery Interaction
 
6.10 Logging of Authentication and Service Discovery Interaction
If needed, you can log interactions with the Delivery Platform. To enable logging, use the parameters RestEnableLog and RestLogFileName in the EMA configuration file or programmatic configuration in the Consumer Group. If Service Discovery is done from the application, logging may be enabled only via function call configuration. For details on these parameters, refer to the Enterprise Message API C++ Configuration Guide.
