Well, I have installed and configured ELK on my own server to ingest and analyze IIS logs and Windows events of few servers. Having a standalone ELK server is filling my needs for now.
But, I had some error messages about expired license, and I had to deinstall X-Pack. Have still this annoying message on Kibana saying my trial period has expired (that should be ackonledged every time I connect to).
Ok I tried to figure out what is exactly the ELK license model. What is really long-term free and what is not, among all modules ElasticSearch, Logstash, Kibana, X-Pack, etc... Someone to clarify ? Web site is not really clear about all these free, basic, trial period, etc...
Edit : and what is the procedure to have a long-term free solution with/without updates and/or what is the very first level of licence to get minimal but functional solution ?
At some point you must have triggered a trial license. Either you did that explictly on 6.3, or you upgraded from an earlier version of Elasticsearch where the default starting license was a trial.
You just need to switch back to a basic license through Kibana or the API
