Writing log data to syslog using log4j

Question

I cannot write log messages to syslog. Any help would be great. Here is my simple log4j program

import org.apache.log4j.Logger; import java.io.*; import java.sql.SQLException; import java.util.*; public class log4jExample { /* Get actual class name to be printed on */ static Logger log = Logger.getLogger(log4jExample.class.getName()); public static void main(String[] args) throws IOException,SQLException { log.error("Hello this is an error message"); log.info("Hello this is an info message"); log.fatal("Fatal error message"); } } 

My syslog properties file

 # configure the root logger log4j.rootLogger=INFO, SYSLOG # configure Syslog facility LOCAL1 appender log4j.appender.SYSLOG=org.apache.log4j.net.SyslogAppender log4j.appender.SYSLOG.threshold=WARN log4j.appender.SYSLOG.syslogHost=localhost log4j.appender.SYSLOG.facility=LOCAL4 log4j.appender.SYSLOG.layout=org.apache.log4j.PatternLayout log4j.appender.SYSLOG.layout.conversionPattern=[%p] %c:%L - %m%n

Add the following lines to the rsyslog.conf file

 $ModLoad imudp $UDPServerRun 514 

It worked for me.

You need to restart rsyslog after modifications.
