# TelnetAppender Class Reference

Inherits AppenderSkeleton.

List of all members.

## 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:

Name | Requirement | Description | Sample Value
Port | optional | This parameter determines the port to use for announcing log events. The default port is 23 (telnet). | 5875
