Java Logstash TCP input w/JSON编解码器将每一行视为一个单独的事件

我试图使用Logstash JSON编解码器通过Logstash TCP套接字读取log4j v2.3 JSON输出，但Logstash将每一行作为单独的事件进行索引，而不是将每一个JSON对象作为事件读取

log4j配置

<Appenders>
    <Console name="console" target="SYSTEM_OUT">
        <PatternLayout pattern="%d %p [%c] - &lt;%m&gt;%n"/>
    </Console>
    ... removed for brevity ...
    <Socket name="logstash" host="localhost" port="4560">
      <JSONLayout />
    </Socket>
</Appenders>
<Loggers>
    <Logger name="org.jasig" level="info" additivity="false">
        <AppenderRef ref="console"/>
        <AppenderRef ref="file"/>
        <AppenderRef ref="logstash"/>
    </Logger>
    ... removed for brevity ...
    <Root level="error">
        <AppenderRef ref="console"/>
        <AppenderRef ref="logstash"/>
    </Root>
</Loggers>

input {
  tcp {
      port => 4560
      codec => json
  }
}
output {
  elasticsearch {}
  stdout {}
}

input {
  tcp {
      port => 4560
      codec => multiline {
        pattern => "^\{$"
        negate => true
        what => previous
      }  
  }
}

filter {
  json { source => message }
}

output {
  elasticsearch {}
  stdout {}
}

日志存储输出

每一行都被解析为一个单独的JSON对象，而不是将整个JSON对象视为一个事件

提前感谢您的帮助。

好吧，我让它工作起来了。这不是我想要解决它的方式，但它确实有效

我没有使用

json

编解码器，而是使用

multiline

编解码器进行输入，并使用

json

过滤器

input {
  tcp {
      port => 4560
      codec => json
  }
}
output {
  elasticsearch {}
  stdout {}
}

input {
  tcp {
      port => 4560
      codec => multiline {
        pattern => "^\{$"
        negate => true
        what => previous
      }  
  }
}

filter {
  json { source => message }
}

output {
  elasticsearch {}
  stdout {}
}

这是正确索引的输出

这似乎有点脆弱，因为它依赖于log4j格式化json的方式，所以我仍然很想知道如何让

json

codec处理多行json输出
