Hello,

I m looking for a way (maybe with grok), to create new field by extracting some specified pattern but with keeping the field message without modification after operation

Example Pattern

2023-01-23 10:33:25 [ALB-ID : Root=1-63ce151d-11eb303302cfe4382c61a851] [7640768e8bb07414] [7640768e8bb07414] [boundedElastic-144] INFO c.o.a.decorators.DataDecorator.processResponse(105) - requestId: 99f49b2e-186493, method: POST, url: /api/Communication/acl/webhook, RawStatusCode :200 TOTAL\_TIME\_TAKEN :26ms

Need to create new field TOTAL\_TIME\_TAKEN with value 26ms

If you like to separate the number and the unit:

```auto
grok {
      match => { "message" => "TOTAL_TIME_TAKEN :%{INT:totaltimetaken:int}%{GREEDYDATA:unit}" }
 }

```

Or you want in a single value:  
match =\> { "message" =\> "TOTAL\_TIME\_TAKEN :TOTAL\_TIME\_TAKEN :%{GREEDYDATA:totaltimetaken}" }
