You can also get the Elasticsearch Head Plugin for Chrome, which is very useful and will be compatible with 5.x versions of Elasticsearch when Metron upgrades (plugins from 2.x are no longer available in v5.6). https://chrome.google.com/webstore/detail/elasticsearch-head/ffmkiejjmecolpfloofpjologoblkegm Just plugin the address http://node1:9200/ and hit connect. I believe our default status is "yellow." But that should be sufficient. I also second Simon's comments about reading up on Elasticsearch.
