我想使用logstash为每条记录导入conversation.lines（忽略info等其余信息），并且可能运行一些逻辑，例如根据时间属性删除一些行。

是否可以单独使用 Logstash，或者我应该预处理文件？

【问题讨论】：

这些 JSON 文档是在单行上，还是如上所示打印得很漂亮？
每个文档都是一行，打印不漂亮，但第一行包含计数和状态字段
您能否展示 JSON 数据在您要处理的文件中的确切是什么样的？
感谢回复，请看我的修改
Logstash 擅长逐行解析文本文件，但如果要解析多行 JSON 文件，那不是我的首选。

【解决方案1】：

我认为最简单的方法是使用 node.js。

require 你的 JSON 文件
循环遍历records
循环遍历conversation.lines
应用你的逻辑
使用 JS ES 客户端将每一行发送到 ES

Logstash 非常擅长逐行解析文本文件，但如果要解析多行 JSON 文件，那可不是我的首选。
