Hello! How can I remplace the value of @timestamp with the value that I get with a regular expresion? I need change the value of @timestamp because when the data is indexed in elasticsearch it shows in this field the value when the data was indexed instead of when data was logged in the file. Thank you! ---

Use a [date](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html) filter. ---
