How should log4j.properties look like?

After discussion here I still cannot configure my program/chainsaw

When I start ChainSaw I choose

And in my program i set configuration:

PropertyConfigurator.configure("log4j.properties");

And finally run program, and click Simple Receiver in Chainsaw

log4j.properties version1

log4j.rootLogger=DEBUG, server

log4j.appender.server=org.apache.log4j.net.SocketAppender
log4j.appender.server.Port=4445
log4j.appender.server.RemoteHost=localhost
log4j.appender.server.ReconnectionDelay=10000

log4j.properties version2

log4j.rootCategory=DEBUG, zeroconf, chainsaw
# Socket Appender
log4j.appender.chainsaw=org.apache.log4j.net.SocketAppender
log4j.appender.chainsaw.remoteHost=localhost
log4j.appender.chainsaw.port=4445
log4j.appender.chainsaw.locationInfo=true

none of them work. What should I do?

As of version 2.4, Log4j now supports configuration via properties files. Note that the property syntax is NOT the same as the syntax used in Log4j 1.

appender.server.type=Socket
appender.server.name=server
appender.server.port=4445
appender.server.host=localhost
appender.server.reconnectDelayMillis=10000

...

rootLogger.appenderRef.server.ref = server

You might have a problem with reconnectionDelayMillis. In logging-log4j-dev mailing list archives I found out that:

The documentation (https://logging.apache.org/log4j/2.x/manual/appenders.html#SyslogAppender) still has the parameter listed as "reconnectionDelayMillis" but the code is now obviously looking for "reconnectDelayMillis". I'm going to change my config to use the new name, but I thought I'd point out the disconnect as it had me confused for a bit. Thanks - Sam

This might be fixed/unified already, but I haven't checked that in the newer versions of log4j. If you encounter any problem try using reconnectDelayMillis.

More detailed example can be found under Configuration with Properties.

try:

log4j.threshold=ALL
log4j.debug = true
log4j.rootLogger=DEBUG, chainsaw
# Socket Appender
log4j.appender.chainsaw=org.apache.log4j.net.SocketAppender
log4j.appender.chainsaw.RemoteHost=localhost
log4j.appender.chainsaw.Port=4445
log4j.appender.chainsaw.LocationInfo=true

This is good example of chainsaw configuration which is also required:
