[New_Installation] Unable to fetch mapping

Hi, I cannot configure an index pattern beause I have a grey button.
I follow the steps intructructions to http://www.itzgeek.com/how-tos/linux/centos-how-tos/updated-install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-7-rhel-7.html

I can connect to kibana in port 5601 but not in elasticsearch on port 9200. (with web browser).
the command "curl -X GET http://localhost:9200" results is OK.
I try differents things like filebeat-*, shakes, elasticsearch, logstash or .kibana in index name but no success.
.kibana give a time-field name value but with a blank choice.

What's wrong in my parameters ?

Thanks a lot.

Its fine, elasticsearch unlike kibana does not have GUI interface by default , you can install plugins like head, hq to get a web ui of your shards and indexes.

How install this plugins ?

You can install head plugin from this link :

OK. T try that. Thanks

Did you send data to ES?
