Weblogic 12C sending logs to syslog - unix

Question

I want to send my weblogic log to syslog. here is what I have done so far.
1.Included following log4j.properties in managed server classpath -
log4j.rootLogger=DEBUG,syslog
log4j.appender.syslog=org.apache.log4j.net.SyslogAppender
log4j.appender.syslog.Threshold=DEBUG
log4j.appender.syslog.Facility=LOCAL7
log4j.appender.syslog.FacilityPrinting=false
log4j.appender.syslog.Header=true
log4j.appender.syslog.SyslogHost=localhost
log4j.appender.syslog.layout=org.apache.log4j.PatternLayout
log4j.appender.syslog.layout.ConversionPattern=[%p] %c:%L - %m%n
2. added following command to managed server arguments -
-Dlog4j.configuration=file :<path to log4j properties file> -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger -Dweblogic.log.Log4jLoggingEnabled=true
3. Added wllog4j.jar and llog4j-1.2.14.jar into domain's lib folder.
4.Then, from Admin console changed logging information by doing the following. "my_domain_name"--->Configuration--->Logging--->(Advanced options)-->Logging implementation: Log4J
Restart managed server.
I used this as refernce. But didnt get anaything in syslog(/var/log/message). What am I doing wrong?

Answer 1

I would recommend a couple items to check:
Remove the space in DEBUG, syslog in the file
Your last two server arguments have a space between the - and the D so make sure that wasn't just a copy and paste error in this post.
Double check that the log files are in the actual classpath.
Double check from a ps command, that the -D options made it correctly into the start command that was executed.
Make sure that the managed server has a copy of the JARs correctly as they would get synchornized from admin during the restart.
Hopefully something in there will help or give an idea of what to look for.

I figured out the problem. My appender was working fine, the problem was in rsyslog.conf. Just uncommented following properties
# Provides UDP syslog reception
#$ModLoad imudp
#$UDPServerRun 514
We were appending the messages, but the listner was abesnt, so it didnt knew what to do with it.
and from *.debug;mail.none;authpriv.none;cron.none /var/log/messages it figures out where to redirect any (debug in this case) information to messages file.
