log4j telnet appender, example needed 1

[hDepotRacing20]

Im trying to figure out how to use the telnet appender. Very little documentation on and have found no working examples to show its use. Anyone know how to use the telnet appender and be willing to give a short example of using in log4j properties file.. Thnx

It is configured just like any other appender with the addition of being able to specify a port (which defaults to 23 - the standard Telnet port)

For example, I set this up in my log4j.properties file

log4j.rootLogger=DEBUG, Remote

# Remote Telnet Appender
log4j.appender.Remote=org.apache.log4j.net.TelnetAppender
log4j.appender.Remote.port=23
log4j.appender.Remote.layout=org.apache.log4j.PatternLayout
log4j.appender.Remote.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

I then started my application which writes to this logger, and was then able to open a separate command window and type

telnet localhost

Logging output began to appear in the telnet session. Well cool.

Obviously, if the application is running on a machine which already has a Telnet server on port 23 or you don't have security rights for Log4j to create a socket on port 23, then you'd need to use a different port.

Hope this helps.
