What is the difference between @timestamp and timestamp?

Elastic Stack Elasticsearch
1

The timestamp field usually have a "@" prefix. Why? What is the difference if we do not add it ?

2

@ fields are usually ones generated by Logstash as metadata ones, @timestamp being the value that the event was processed by Logstash.

Hi Mark

Nice to see you. Thanks for your answer. So it means we can change the @timestamp to timestamp if we want, right?
As long as we are not using logstash

If you want, yes.
