/** \defgroup ChannelLogging Channel logging macros
 *
 * These macros augment the log message with some channel-specific information,
 * such as the local URI, that are useful to distinguish which channel produced
 * the message. It is strongly recommended to use these macros instead of the
 * generic ones for all logging inside Channel subclasses.
