HEC event formatting: How to configure Splunk to show only message field and not all fields?

[redg]

Good evening,
With a Java Spring Boot application, I use the library provided by Splunk to send to Splunk the logs using
com.splunk.logging.HttpEventCollectorLogbackAppender.

By default when I do a search in Splunk, the event appears like this (see image below).

But I'd rather default the search to return results in this form.

Is it possible to configure Splunk (Source types, etc..)  to display only the message field and not the entire event with all the fields?

@redg You could use the HEC Raw-Endpoint (Format events for HTTP Event Collector - Splunk Documentation) and parse & transform the events as needed.
