Hello everyone,

How could I cut a field in a sentence? I looked, there is a filter split module but I do not know how I can use it.

Example: path =\> h2dd\_AMR\_20180612-2357.log

what want:  
fields\_1: ​​AMR  
date: 20180612  
hour: 23h57

Is it possible ?

If they always look like this then I would use dissect.

```
dissect { mapping => { "message" => "%{}_%{field1}_%{date}-%{hour}.%{}" } }

```
