public class SpotifyInternalAppender
extends MillisecondPrecisionSyslogAppender

A SyslogAppender that uses millisecond precision, and that by default configures its values for SyslogAppenderBase.syslogHost and SyslogAppenderBase.port based on the environment variables specified in LoggingConfigurator.SPOTIFY_SYSLOG_HOST and LoggingConfigurator.SPOTIFY_SYSLOG_PORT. If the configuration explicitly sets the SyslogAppenderBase.syslogHost or SyslogAppenderBase.port values, the environment variables will not be used. Note that logback's configuration support allows you to use environment variables in your logback.xml file as well (see http://logback.qos.ch/manual/configuration.html#scopes).
