Log4j SocketAppender with DailyRollingFileAppender

This will create a centralized logging mechanism by using log4j
This will create daily one log-file


Step 1: -
     Create a file called log4j-server.properties and add the below content

log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p - %m%n
log4j.appender.R.File=C:/logs/examples
log4j.appender.R.DatePattern='-'yyyyMMdd'.log'

Step 2:-
    Copy log4j-1.2.7.jar into your folder or where log4j-server.properties


Step 3:-   
    Go to cmd prompt and run with the following command.

    Ex:-
   
        D:\Log4j-server\server>    java -classpath log4j-1.2.17.jar org.apache.log4j.net.SimpleSocketServer 4712 log4j-Server.properties
        or
        D:\Log4j-server>   java -classpath .\Server\log4j-1.2.17.jar org.apache.log4j.net.SimpleSocketServer 4712 .\Server\log4j-Server.properties


Step 4:-
    Create a client log4j.properties and add the below content

log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.net.SocketAppender
log4j.appender.R.Port=4712
log4j.appender.R.RemoteHost=localhost
log4j.appender.R.ReconnectionDelay=10000

Step 5:- 

            Your Java program.

public class LogTest
{
    private static org.apache.log4j.Logger    log    = Logger.getLogger ( LogTest.class );

public static void main ( String [] args ) throws Exception
    {
      
            log.info ( "First Info Message!" );

            log.trace ( "First Trace Message!" );
            log.debug ( "First Debug Message!" );
            log.warn ( "First Warn Message!" );
            log.error ( "First Error Message!" );
            log.fatal ( "First Fatal Message!" );

}
}
