        Live charts and statistics for elasticsearch cluster.

        This plugin works only for elasticsearch 1.0.0 or higher:

• Go to elastic search home directory: 
Generally ES_HOME is /usr/share/elasticsearch
cd  /usr/share/elasticsearch                                                                                                                           
• Navigate to the node installation folder and run the following command: 
$  ./bin/plugin -install lukas-vlcek/bigdesk                                                                                                     
• To install a specific version (for example 2.4.0) run: 
$  ./bin/plugin -install lukas-vlcek/bigdesk/2.4.0                                                                                                
• Then you can navigate your web browser to http://<elasticsearch_REST_endpoint>/_plugin/bigdesk/

for example in case of localhost:
http://localhost:9200/_plugin/bigdesk/#cluster
