Logging
Overview
HydraExpress provides two types of loggers: its primary Agent global logger, and a Web services-specific logger, each with a specific use: 

Use the 
Agent logger to log events from services, connectors, transports, and handlers. It is not available to client-side applications or standalone servers. 

Use the 
Web services logger to log events from a client or a standalone server. While this logger is also available to server-side code, we recommend using the Agent logger for services. 
NOTE: 	The Agent logger is not available to services hosted outside the Agent.
This chapter discusses the Agent logger in detail (
The Agent Logger), and includes an introduction to using the Web services logger in client applications (
The Web Services Logger for Client Applications). For a detailed look at the Web services logger, see 
“Web Service Logging,” in the 
HydraExpress Web Service Development Guide.
