2.2.1 SocketAppender
The SocketAppender allows to send the logging information to a TCP port.
The Logging Collector provides two TCP inputs. The former receives java log4j
LoggingEvent objects (org.apache.log4j.spi.LoggingEvent) from java applications. The latter
instead more generic can receive logging information in XML format (log4j compliant) from
non-java applications such as C or C++ applications.
The outputs of the logging collector called appenders are:
• Socket Appender
• JMS Appender
• DB Appender
The collector’s outputs are used to allow the persistent storage, the display and the
distribution of the logging information.
