Logstash仅发送json

我正在通过logstash发送日志

2017-02-27T13:00:07+01:00    test    {"createdAt":"2017-02-27T13:00:07+0100","cluster":"undefined","nodeName":"undefined","nodeIP":"10.11.11.50","clientIP":"10.11.11.72","customerId":1,"identityId":332,"appType":"admin","eventGroup":"education","eventName":"insert","eventData":{"education_insert":{"type":"course","data":{"education_id":2055,"education":{"id":2055,"customer_id":1,"creator_id":332,"type":"course","status":"new","is_featured":false,"enroll_deadline":null,"complete_deadline":null,"count_view":0,"count_like":0,"meta_title":"test Course - progress","meta_description":"test Course - progress","discoverable":"everyone","progress_max":0,"instructor_ids":[332],"tag_ids":[135],"discoverable_group_ids":[],"category_ids":[14],"audits":null,"instructors":null,"creator":null,"lessonGroups":null,"categories":null},"duration":"quick"}}},"scopeType":"education","scopeId":"2055"}

如何删除

2017-02-27T13:00:07+01:00

和

test.app.event

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

mutate

删除您不希望在最终事件中使用的任何字段（例如，

message

）。

您可以使用regex模式，以便只获取

json

。

regex

模式应位于模式文件中：

该模式可能看起来像：

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

现在，该消息只有日志行中的

JSON

部分，因此现在可以通过

logstash

将它们推送到ES。以上只是一个样本，因此您可以复制

希望有帮助

我用这个为我工作：）谢谢你的帮助

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"}}

转到你说的“发送日期时间，然后测试，然后json”的那一行，删除前两项：）要获得更详细的答案，你可能需要在你正在做的事情中添加一些细节，因为调试这个几乎是不可能的：）我只需要发送json数据，但我不知道如何使用filterIn grok删除logstash中的前两项我必须使用“匹配” ?

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"}}
