UDP input plugin fails with SocketError: bind: name or service not known

Question

这是我的 logstash 配置文件。我想通过使用类型来使用多个配置文件。

input {
  udp { 
    port => 62555
    type => 4444 
  } 
}
output {
   if [type] == "4444" {
   }
}

错误是：

←[33mUDP listener died {:exception=>#<SocketError: bind: name or service not   known>, :backtrace=>["org/jruby/ext/socket/RubyUDPSocket.java:157:in `bind'","F:/elasticsearch-2.3.1/logstash-2.3.4/vendor/bundle/jruby/1.9/gems/logstash-input-udp-2.0.5/lib/logstash/inputs/udp.rb:67:in `udp_listener'", "F:/elasticsearch-2.3.1/logstash-2.3.4/vendor/bundle/jruby/1.9/gems/logstash-input-udp2.0.5/lib/logstash/inputs/udp.rb:50:in `run'", "F:/elasticsearch-2.3.1/logstash-2.3.4/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.4-java/lib/logstash/pipeline.rb:342:in `inputworker'", "F:/elasticsearch2.3.1/logstash-2.3.4/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.4-java/lib/logstash/pipeline.rb:336:in `start_input'"], :level=>:warn}←[0m

udp 输入插件的 type 选项需要一个字符串（参见 documentation）：

type
Value type is string
There is no default value for this setting.

因此您需要在 type 选项周围添加 "。

端口是udp输入的必选项，如果有问题，需要更改服务器配置。
