Have you done any basic network tests to make sure you can connect to your
syslog server from the remote machines?

This is directing the root logger to use your ConsoleAppender, not the
SyslogAppender. This means anything that you do not specifically send to the
SyslogAppender will be sent to stdout. Probably not what you want here.

Have you followed the instructions for using Log4j with Tomcat?
http://tomcat.apache.org/tomcat-7.0-doc/logging.html#Using_Log4j
I’d suggest you get Log4j working to a local file first. Then add the
SyslogAppender and try sending them to your syslog server. It will make
troubleshooting easier if you know that you have Log4j working before you try
to setup syslog.
