SyslogAppender not working

Question

I have a java program and I want to enter the / var / log / messages file on the fedora computer. I am using log4j SyslogAppender but it does not work.

my log4j properties file contains

# Set root category priority to INFO and its only appender to CONSOLE. log4j.rootCategory=INFO, CONSOLE, SYSLOG #log4j.rootCategory=INFO, CONSOLE, LOGFILE # Set the enterprise logger priority to DEBUG log4j.logger.com.locaid=INFO, CONSOLE, LOGFILE, SYSLOG # CONSOLE is set to be a ConsoleAppender using a PatternLayout. log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n # LOGFILE is set to be a File appender using a PatternLayout. log4j.appender.LOGFILE=org.apache.log4j.FileAppender log4j.appender.LOGFILE.File=/home/dev/app.log log4j.appender.LOGFILE.Append=true log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout log4j.appender.LOGFILE.layout.ConversionPattern=[%d{dd/MM/y HH:mm:ss}][%t][%1p] %c - %m%n log4j.appender.SYSLOG=org.apache.log4j.net.SyslogAppender log4j.appender.SYSLOG.syslogHost=localhost log4j.appender.SYSLOG.layout=org.apache.log4j.PatternLayout log4j.appender.SYSLOG.layout.conversionPattern=%d{ISO8601} %-5p [%t] %c{2} %x - %m%n log4j.appender.SYSLOG.Facility=LOCAL1 log4j.appender.SYSLOG.Threshold=debug log4j.appender.SYSLOG.FacilityPrinting=true 

in /etc/rsyslog.conf I have

 local1.* /var/log/app.log 

in the file / etc / sysconfig / rsyslog there is

 SYSLOGD_OPTIONS="-r -m 0 -c 4" 

When the rsyslog service is restarted, the app.log file is created, but no logs are added. I also tried using the default USER tool, but it doesn’t work, although logger -p LOCAL1.info cmd works and adds the log to app.log. Need help.

Answer 1

I don't see anything bad at the end of log4j, but my /etc/default/rsyslog (on Ubuntu) says

 # Options for rsyslogd # -m 0 disables 'MARK' messages (deprecated, only used in compat mode < 3) # -r enables logging from remote machines (deprecated, only used in compat mode < 3) # -x disables DNS lookups on messages received with -r # -c compatibility mode # See rsyslogd(8) for more details 

which assumes that -r and -m 0 will not work in combination with -c 4 . Instead of trying to set up remote access here, you should edit your /etc/rsyslogd.conf and add (or uncomment)

 $ModLoad imudp $UDPServerRun 514

See if this can help you as it works great for me! Regards Anand Bhat

Answer 3

Problem here

 SYSLOGD_OPTIONS="-r -m 0 -c 4" 

Must be

 SYSLOGD_OPTIONS="-r -m 0" 

These options do not work together.
