As a matter of fact, I played with the now deprecated Elastiflow, however I couldn't get my head around managing ELK, scrapped it pretty quickly, and Netflow did not reach the meaningful stage at that time. OpenNMS looks pretty massive that I can't run it at the moment. Thanks for suggestion though.
