Check out the multiline timestamp example below.

Right, but there is no specific indicator for me to consider multi lines as a single event. By looking at the above example, can you please specify how I can use an indicator or a regex pattern?

The pattern should be

```auto
codec => multiline {
      pattern => "^\d\d\d\d\d\d\d\d:\d\d:\d\d:\d\d:\d\d\d\d\d\d
      negate => true
      what => previous
    }

```
