我收集的数据正在将数据发送到端口25826的Logstash,但是我在运行Logstash时看到此错误

UDP listener died {:exception=>#<SocketError: bind: name or service not known>, :backtrace=>["org/jruby/ext/socket/RubyUDPSocket.java:160:in `bind'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-udp-2.0.5/lib/logstash/inputs/udp.rb:67:in `udp_listener'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-udp-2.0.5/lib/logstash/inputs/udp.rb:50:in `run'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.2-java/lib/logstash/pipeline.rb:342:in `inputworker'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.2-java/lib/logstash/pipeline.rb:336:in `start_input'"], :level=>:warn}

有人知道这里的解决方案吗？

解决方法:

得到解决

• No error at Logstash the collector collectd was not sending the data
  to logstash udp port corrected it by adding conf in network plugin of
  collectd enabled that plugin in collectd.conf and replace hostname with logstash host and udp port.
