Kibana

Kibana is an open source (Apache Licensed), browser based analytics and search dashboard for Elastic Search. Kibana is a snap to setup and start using. Written entirely in HTML and Javascript it requires only a plain webserver, Kibana requires no fancy server side components. Kibana strives to be easy to get started with, while also being flexible and powerful, just like Elastic Search.
