As we are on Splunk 7 we do not use the "X-Splunk-Request-Channel"
The data is recieved by an heavy forwarder and parsed to the indexer cluster.
The data is arriving at the assigned index but the problem is that splunk handles the whole file as one event.
I created a sourcetype on a test environment which breaks up the events in single events when i upload the file manually.
But when i send this file to our productive environment via the HEC with /raw endpoint the file is still indexed as one event.
I tried to configure the sourcetype on all indexers in the index cluster -> was nor working
I tried to configure the sourcetype also at the heavy forwarders -> not working
The event endpoint expects properly formed JSON and things broken into events. It bypasses parsing queues. If you send to RAW you treat it like any file pickup ingestion and do your own line breaking etc as you would any text stream multi line event.
