How to know elastic search installed version from kibana?

Question

Currently I am getting these alerts:

Upgrade Required Your version of Elasticsearch is too old. Kibana requires Elasticsearch 0.90.9 or above.

Can someone tell me if there is a way I can find the exact installed version of ELS?

Answer 1

from the Chrome Rest client make a GET request or curl -XGET 'http://localhost:9200' in console

rest client: http://localhost:9200

{     "name": "node",     "cluster_name": "elasticsearch-cluster",     "version": {         "number": "2.3.4",         "build_hash": "dcxbgvzdfbbhfxbhx",         "build_timestamp": "2016-06-30T11:24:31Z",         "build_snapshot": false,         "lucene_version": "5.5.0"     },     "tagline": "You Know, for Search" } 

where number field denotes the elasticsearch version. Here elasticsearch version is 2.3.4

Answer 2

I would like to add which isn't mentioned in above answers.

From your kibana's dev console, hit following command:

GET / 

This is similar to accessing localhost:9200 from browser.

Hope this will help someone.
