Hi,
The local Splunk folks recommended we switch from a universal forwarder to a light-forwarder in our dev env. I installed the full splunk image, and enabled light-forwarding, but now I'm seeing "Connection to XX.XX.XXX.XX:8089 closed. Read error. Connection reset by peer" messages. I enabled light-fowarding, and added the forwarder destination. Is this port right? Not sure what I missed here...

Port 8089 is used for intra-splunk communication (license info, deployment traffic, etc), not for sending and receiving logs. You should configure the forwarder to send its logs to a port that has been setup for receiving forwarded logs on the indexer - which port number it has depends on what port the indexer has been configured to use, but port 9997 is commonly used for this.
Some docs on the subject:

No, you only need one output per indexer from the forwarder, regardless of how many sources (files, ports, scripts, ...) the forwarder has.

Ah, gatcha. Wasn't sure if there was some sort of "funnel", where I read from different ports and sent them over a different one. So, if I read 3 different ports, I should have 3 corresponding outputs to the indexer?

I am seeing it in the splunkd.log on the agent server. I used port 8089 as the forwarder port - I don't see any doc that states what port to use.

Where are you seeing this error? What port did you configure the forwarder to send its events to?
