java - What's wrong with my logback syslog appender? -

i'm trying logback syslog appender working, , i've got misconfigured. i've created small sample project think should log syslog, yet doesn't.

i'm sure i'm missing stupid. here's appender logback.xml:

<appender name="syslog" class="ch.qos.logback.classic.net.syslogappender">     <sysloghost>localhost</sysloghost>     <facility>user</facility>     <suffixpattern>[%thread] %logger %msg</suffixpattern> </appender> 

i've tried adding port (514) explicitly, and, no joy. on both systems i've tried on, i've verified syslog receiving input using logger "test message" , tailing either /var/log/messages or /var/log/system.log.

what need change in order logback/slf4j logging syslog?

nothing wrong code, problem system config. using provided test project, able make syslog appender work (ubuntu 14.10).

here steps:

• edit /etc/syslog.conf , ensure have network syslog enabled:

# provides udp syslog reception $modload imudp $udpserverrun 514  # provides tcp syslog reception # note logback seems use udp, isn't strictly necessary. $modload imtcp $inputtcpserverrun 514 

• restart rsyslog (service rsyslog restart) if change config (reload doesn't work)
• check syslog listening lsof -i | grep syslog

results:
