Kibana is a great tool which connects directly to Elasticsearch, it all based on html, javascript and css and without any server side scripting => Kibana run directly in your browser and connects your browser to Elasticsearch on port tcp:9200.

To run Kibana we can use any common http server like Nginx or Apache.

Download https://download.elasticsearch.org/kibana/kibana/kibana-3.0.0milestone4.tar.gz and extract Kibana into a folder like /var/www/html/kibana/

Point the config to Elasticsearch server (this server also) : # vim /var/www/html/kibana/config.js

elasticsearch: "",

Make sure the browser can connect to Turn any firewall in between to off.

At last, we should have a dashboard like this :
