消息为空

Question

logstash 5.3.0

filter {
  grok {
    patterns_dir => ["/etc/logstash/patterns"]
    match => [
               "message", "%{NGINXACCESS} %{GREEDYDATA:message}",
               "message", "%{NGINXACCESSAUTH}%{GREEDYDATA:message}",
               "message", "%{NGINXERROR}",
               "message", "%{PHPLOG}%{GREEDYDATA:message}",
               "message", "%{FPMERROR}%{GREEDYDATA:message}",
               "message", "%{SYSLOG5424PRI}%{SYSLOGBASE2} %{GREEDYDATA:message}"
    ]
    overwrite => [ "message" ]
  }

我在这里遇到一个问题，我在这里为NGINXACCESSAUTH提供了一个完整的解析，这让我得到％{GREEDYDATA：message}的空结果，并且这不会重写消息字段为空，让我的消息字段的结果很混乱完整的rsyslog源消息以及解析的所有标记。

除了删除部分模式之外，还有什么想法可以解决这个问题，以便GREEDYDATA可以解析一些内容吗？

Answer 1

使用keep_empty_captures => true保留空消息
