How to extract field from log in Log monitoring V2


I'm new in the community and in the use of Dynatrace.

There is someway to extract specific fields in a custom trace log.

I associate the custom log to the process but I don't find a way to extract and create a custom field.


For example if I have a logfile with these line pattern:

25/01/2021 ORD1234 OK

Is there some way to identify the ORD1234  as NrOrder and OK as Result fields to use in the search text for post processing?


Thank's a lot for helping me

Hi Babar, 

thank for your reply. I have some doubt because in this article it seems that the custom metric is to built only for json log  but i don' t understand if this is possible for log4Net , log4j or custom log defining some rule or regular expr to extract a specific field as a metric. 
thanks a lot for your support



Hi dcappare,

You are correct, you can create custom metrics from API ingested logs in JSON at the moment.

Extracting specific fields from plaintext logs will be available soon!


Best regards,

Any information on which release it is planned? Looking forward to it too.

Most precise information will definitely be in the release notes, but the team will post here too when a release time is certain-

@HansLougas : Do you have an ETA for this feature ?

Hi, I am eager to share a specific ETA, but currently asking to please hold.

I will keep this thread posted as soon as we have ETA.

Thanks for posting this here also Mathias!

I recommend watching through the whole Observability Clinic session, but if you're curious about extracting fields from log record, see from 53:26.
