【原创】大数据基础之Logstash（3）应用之http（in和out）

一个logstash很容易通过http打断成两个logstash实现跨服务器或者跨平台间数据同步，比如原来的流程是

logstash: nginx log -> kafka

打断成两个是

logstash1: nginx log -> http out

logstash2: http in ->kafka

具体如下

http out

filter {
    ruby {
      code => "event.cancel if not event.get('message').include?'something'"
    }
  }

output {
    http {
      url => "http://test.server:10000"
      codec => "plain"
      format => "json"
      content_type => "application/json"
      http_method => "post"
    }
}

可以通过filter跳过不需要的记录

http in

input {
    http {
        host => "0.0.0.0"
        port => 10000
        additional_codecs => {"application/json"=>"json"}
        codec => "plain"
        threads => 4
        ssl => false
    }
}

http in
