How to know elastic search installed version from kibana?
<p>Currently I am getting these alerts:  </p>

<blockquote>
  <p>Upgrade Required Your version of Elasticsearch is too old. Kibana requires Elasticsearch 0.90.9 or above.</p>
</blockquote>

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