弹性搜索中的@timestamp和timestamp字段之间的区别 [英] Difference between @timestamp and timestamp field in elasticsearch

问题描述

当我使用日志存储记录一些请求进行弹性搜索时，它将@timestamp字段放置为时间。
当我使用NEST记录这些请求并设置timestamp字段时，它会放置时间戳字段。

When I logged some requests to elastic search using log stash, it puts @timestamp field as time. And when I logged those requests using NEST and set timestamp field, it puts timestamp field.

当我使用kibana看到数据时，这2个字段具有单独的名称。他们之间有什么区别？

When I see data using kibana, those 2 fields have separate name. What is difference between them?

推荐答案

@timestamp字段是一种用于日志存储的内部字段。这就是为什么@符号在字段前面。可以是存储时间戳的任何其他字段。就像elasticsaerch使用_一些内部字段。

The @timestamp field is kind of an internal field for log stash. That is why the @ sign is in front of the field. Could be any other field that stores a timestamp. Just like elasticsaerch uses the _ for some internal fields.
