如何删除2017-02-27T13:00:07+01:00和test.app.event

Answer 1

您需要使用grok提取消息的JSON部分，然后使用json过滤器将提取的JSON转换为事件。最后，您需要使用最终事件中不需要的mutate删除任何字段（例如，message）。

Answer 2

您可以使用 REGEX 模式仅获取json。regex模式应在您的模式文件中：

模式看起来像：

REQUIREDDATA {([^}]*)}([^}]*)([^}]*)}}}([^}]*)} <-- this extracts only your json part

测试的正则模式。

此后，您可以在 grok 匹配中使用图案：

grok {
    patterns_dir => ["/pathto/patterns"]
    match => { "message" => "^%{REQUIREDDATA:new}" }            
}

现在，该消息仅在日志行中具有JSON零件，因此您现在可以通过logstash将其推向ES。以上只是一个样本，因此您可以复制。

希望它有帮助！

我用它并为我工作:) thx寻求帮助

input { kafka { bootstrap_servers=>"localhost:9092" topics=>"test"}}
filter{
grok {
    match => { "message" => "%{TIMESTAMP_ISO8601:timestamp}t%{GREEDYDATA:topic}t%{GREEDYDATA:json}" }
  }
  json {
     source => "json"
     remove_field => ["timestamp","topic","json","message","@version","@timestamp","tags"]
  }
 }
output{ elasticsearch {hosts=>["127.0.0.1:9200"] document_type=>"app_stats" index=>"test"}}
