How to ingest a selection of JSON fields?

[PeraltaRH]

I have a dump.json file that collects events in JSON format:
{"key":"value","key":"value","key":"value","key":"value"....}

I have no problem processing it however each line has 400 Keys and I only need 30 of them in splunk.

How can I tell the Universal forwarder to only send those 30 fields to my Indexers?
Ingesting all the 400 fields consumes a lot of resources and license.

Hi

With UF I suppose that the easiest way is use modify the producer so that it writes only those needed events on that json. I suppose that there is some program which continuously writes this file one event per line?

With HF, you could use props and transforms for get ride of unwanted values.
