Below is the format of my logs

```auto
05-08-2022 13:20:13,468 INFO [stdout] (151_bYD2+EULzJ_SLR_124219_-_mymailfc@mailinator.com) Subject: Products Offer exceeded threshold limit of 10%

```

I want to extract the timestamp from this log and store it in a new field so for the above given log new timestamp field should have value "05-08-2022 13:20:13,468".  
can anyone suggest any way to do this ?

Use a dissect filter

```
dissect { mapping => { "message" => "%{newField} %{+newField} %{}" } }

```
