HF logs is missing from _internal index

[tcmarquesi]

I have this Heavy Forwarder apparently not sending its own _internal logs $SPLUNK_HOME/var/log/splunk/*.log to the indexers.

What I've already checked:

1. HF is working fine, delivering data which it's set to receive and forward.

2. HF is phoning Deployment server fine.

3. _audit index is being indexed fine.

4. Using $ splunk list forward-server I see it is properly set to send data only to correct indexers.

5. The logs are being written as expected and have proper reading permissions, e.g.:
   $ ls -ltr ~/var/log/splunk/splunkd.log
-rw------- 1 splunk splunk 12983503 Feb 26 11:43 /opt/splunk/var/log/splunk/splunkd.log

6. Searching for _internal index into HF returns no results as supposed to be.

Any ideas about what is going on?

There is already a question about it in Answers, but not satisfying answered...

Do you see no logs at all? Like, no metrics, no audit data as well or just _internal?

Only _intental, _audit is fine.

you may want to check your outputs.conf for forwardedindex* and see if _internal is missing under tcpout stanza or if you have custom config like - https://docs.splunk.com/Documentation/Splunk/latest/DistSearch/Forwardsearchheaddata
