使用 Nlog 将日志打印到 Logstash 的监控接口

Logstash提供了多种监听日志打印的方式，而Nlog也提供了多种输出日志的方式，当Nlog的输出配置与Logstash的输入配置相对应，就能够让Nlog打印出来的日志都存储到Elasticsearch中

以下介绍3种配置方式：

1. 文件

   Logstash:

   input {
       file {
           path => "D:/Log/Application/*Log.txt"
           type => "Application"
       }
   }
   

   NLog:

   <targets>
       <target xsi:type="File" name="file" filename="D:/Log/Application/${shortdate}Log.txt" layout="${longdate} ${uppercase:${level}} ${message}"/>
   </targets>
   

2. tcp Logstash:

   input {
       tcp{
          port => 8001
          type => "TcpLog"
       }
   }
   

   NLog:

   <targets>
       <target xsi:type="Network" name="tcp" address="tcp://127.0.0.1:8001" layout="${longdate} ${uppercase:${level}} ${message}"/>
   </targets>
   

3. udp Logstash:

   input {
       udp{
          port => 8002
          type => "UdpLog"
       }
   }
   

   NLog:

   <targets>
       <target xsi:type="Network" name="udp" address="udp://127.0.0.1:8001" layout="${longdate} ${uppercase:${level}} ${message}"/>
   </targets>
