Detailed Description

The TelnetAppender is a log4cxx appender that specializes in writing to a read-only socket. The output is provided in a telnet-friendly way so that a log can be monitored over TCP/IP. Clients using telnet connect to the socket and receive log data. This is handy for remote monitoring, especially when monitoring a servlet.

Here is a list of the available configuration options:
