[sha198989]

HI all,
i am getting logs from the syslog server. i have used logstash udp input plugin to get logs via the network. my logstash configuration is this

input{
udp{
port => 5000
type=> syslog
}
}

i am using logstash2.2.4 version on the ubuntu 14.06 system

and i am having this warning
{:timestamp=>"2015-05-09T21:17:44.676000+0000", :message=>"UDP listener died", :exception=>#<SocketError: recvfrom: name or service not known>, :backtrace=>["/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-udp-0.1.3/lib/logstash/inputs/udp.rb:79:in udp_listener'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-udp-0.1.3/lib/logstash/inputs/udp.rb:49:inrun'", "/opt/logstash/lib/logstash/pipeline.rb:174:in inputworker'", "/opt/logstash/lib/logstash/pipeline.rb:168:instart_input'"], :level=>:warn}

Your log message appears to have been mangled, leaving out the interesting part after "exception=>". Please edit your post, paste the log message again, and make sure you format all of it as preformatted text (e.g. using the designated toolbar button).
