HydraExpress supports both client-side and server-side logging. Logging is not implemented in the sample server application by default (although it is implemented on the client side).

HydraExpress provides two types of loggers: its primary Agent global logger, and a Web services-specific logger.

For server-side code, use the Agent logger, which is best for logging events from services, connectors, transports, and handlers. This book does not include a detailed discussion on using the Agent logger; rather, please see “Using the Default Logger in a Service,” in the HydraExpress User Guide.

The Web services logger may provide some use while debugging, as it logs some Fatal and Error level messages. See Server-side Logging through the Web Services Logger for more information.
