-------------------------------------
Summary: SyslogAppender not working
Key: LOG4J2-901
URL: https://issues.apache.org/jira/browse/LOG4J2-901
Project: Log4j 2
Issue Type: Bug
Components: Appenders
Affects Versions: 2.1
Environment: Linux
Reporter: Tihomir Meščić
I'm using Log4j version 2.1 and trying to use a Syslog appender to log to a
syslog server (rsyslog). I'm using the configuration given at the official site
(http://logging.apache.org/log4j/2.x/manual/appenders.html#SyslogAppender):
{noformat}
<Syslog name="RFC5424" format="RFC5424" host="localhost" port="514"
protocol="UDP" appName="MyApp" includeMDC="true"
facility="LOCAL0" enterpriseNumber="18060" newLine="true"
messageId="Audit" id="App"/>
{noformat}
When I start my app and do a LogManager.getLogger(), I get an error:

The same thing works on an older version of log4j 2.0-beta9.
