Deployment Architecture

Should the main index be replicated in an indexer cluster?

I have a distributed splunk deployment with search-head cluster, indexer cluster and forwarders. Currently, the main index is not replicated across the index cluster peers. Is that recommended (or the inverse, NOT recommended)?

I would say "yes", if only for consistency's sake. Ideally little if any data winds up being stored in the main index - but if some does wind up there by accident (or misconfigured app), then it'd be really nice were it replicated.

Exactly... it's the only index that you could "accidentally" put something in... which implies it should be treated like an "intentional" and replicated index. 🙂

With Splunk... the answer is always "YES!". It just might require more regex than you're prepared for!
