Re: [infinispan-dev] Event log
The Hibernate Search project is now working on giving end users the
option to write to either
- Lucene (embedded/local and optionally into Infinispan's Lucene Directory)
- Elastic Search -> would give you ELK integration
- [later] Solr
We have a working prototype, and just yesterday some of the first
steps were merged in master.
This implies that if you write those events into an ad-hoc Infinispan
Cache, you inherit the functionality via Infinispan Query and benefit
from the decoupling and pluggability of our indexing components via a
stable API.
I'd suggest you just write those events into a dedicated Cache; you
could index the cache by default and I'm happy to help defining an
appropriate "domain model" to record such events..
Clearly indexing such a cache has benefits, but assuming you don't
need some Lucene-only statistics you'd have the option for non-indexed
queries and in the near future for ELK connectors.

I really like the idea!
Would it be possible to forward raw data (not aggregated) to the ELK stack
[1]?
This aspect might be important for production systems with centralized
logging.
