Does anybody know, or could advise whether v5 can be used as a heavy forwarder to a 4.3 back end please? I did read the doco, promise...including p11 on known issues. The v5 installed ok on a Linux box including the usual suspects re accepting the T's & C's. The service is running ok. The Indexer is Windows based, all 64 bit.
Damn ...did I down vote something Drainy?! Was it me? I shouldn't feel qualified to have an opinion on this. I've been using a Kindle Fire recently to access the SplunkBase if away from a desktop, and have to say it has yielded some 'unpredictable results'! I know...don't blame the technology 😉
Someone downvoted your answer on your question, I upvoted it again to return the balance to 0 🙂 If someone genuinely answers a question or explains the cause then regardless of if someone did it by mistake, you can't downvote it as a bad answer... because its the answer! Anyway, rant over, nothing to see here...
Yes. Any Forwarder of 4.2+ can be used to send to a 4.2+ indexer, so a 5.x Heavy Forwarder can send to a 4.3 Indexer.
From the Splunk doc:
4.2+/5.0+ forwarders (universal/light/heavy) are backwards compatible down to 4.2+ indexers. For example, a 4.3 forwarder can send data to a 4.2 indexer but not to a 4.1 indexer.
Pre-4.2 forwarders are backwards compatible down to 4.0 indexers.
All indexers are backwards compatible with any forwarder and can receive data from any earlier version forwarder. For example, a 4.2 indexer can receive data from a 4.1 forwarder.
