How to filter fields in my logs before to index in splunk enterprise using ingest actions?

[Alejandro1195]

Hello, I need help to filter fields of an event and in this way reduce the size of the log before indexing it in splunk, I was reviewing the documentation and using ingest actions it is possible to exclude events based on regular expressions, however I do not need to exclude events if not specific fields

Hi,

I'd use SEDCMD in props.conf. You can find more details in the props.conf.spec. This is used for anonymization, but it should also work for your use case.

If you want detailed steps to set it up, you can follow this guide: Anonymize data with a sed script.
