Question

最近，我发现我可以通过直接提供URL直接从Logstash合并数据。提取输入的效果很好，但是它会将完整的文档下载并加载到ES中。

我想为每行创建一个新的弹性搜索记录。默认情况下，整个文件会加载到消息字段中，这会减慢“发现”选项卡等中的Kibana加载。

Logstash配置：

input {
  http_poller {
    urls => {
      bembenek_c2 => "http://osint.bambenekconsulting.com/feeds/c2-ipmasterlist-high.txt"
      bembenek_c2dom => "http://osint.bambenekconsulting.com/feeds/c2-dommasterlist-high.txt"
      blocklists_all => "http://lists.blocklist.de/lists/all.txt"
    }
    request_timeout => 30
    codec => "json"
    tags => c2_info
    schedule => { cron => "*/10 * * * *"}
    metadata_target => "http_poller_metadata"
  }
}

filter {
        grok {
                match => { "message" => [
                                "%{IPV4:ipaddress}" }
                add_tag => [ "ipaddress" ]
        }
}

output {
 stdout { codec => dots }
    elasticsearch {
        hosts =>  ["10.0.50.51:9200"]
        index => "blacklists"
        document_type => "default"
        template_overwrite => true
    }
   file {
        path           => "/tmp/blacklists.json"
        codec          => json {}
    }
}

有人知道如何用“ \ n”分割加载的文件吗？

我尝试过

filter {
split {
terminator => "\n"
}
}

如何使用此过滤器的文档和示例并不流行。

缺少的过滤器是：

filter {
split {
        field => "[message]"
}
}

我们不必指定终止符，因为根据Logstash 6.3文档默认将其设置为“ \ n”。

Logstash拆分过滤器
