This uses the ES health API to get the cluster health status and pretty it up in our index/gate graph pages. The cluster health API is documented here: https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-health.html Also add a note to the readme on how to view the openstack ES cluster health.

Elastic Recheck Dashboard
Elastic Recheck is a handy tool for mining the data in our logstash environment to categorize race conditions in the OpenStack gate. In addition to including a number of command line tools, we provide an html dashboard, because the kids love that html.
Architecture
The dashboard currently consists of static html and a set of javascript libraries, which read json files full of data, and do client side rendering of graphs. This may change in the future.
Below this tree you'll find a set of sub-directories that assume that you are running this in an apache environment.
- static files - /usr/share/elastic-recheck
- dynamic json - /var/lib/elastic-recheck
- apache config - /etc/apache/conf.d/elastic-recheck.conf
Json files directory is expected to be mapped to /elastic-recheck/data and the static files to /elastic-recheck.
Installation
At install time for elastic-recheck the static files are installed as per our assumed location. The apache configuration is not changed, however an example is provided in the conf directory.
