==== Checking that Elasticsearch is running

You can test that your Elasticsearch node is running by sending an HTTP
request to port `9200` on `localhost`:

[source,js]
--------------------------------------------
GET /
--------------------------------------------
// CONSOLE

which should give you a response something like this:

["source","js",subs="attributes,callouts"]
--------------------------------------------
{
  "name" : "Cp8oag6",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
  "version" : {
    "number" : "{version}",
    "build_flavor" : "oss",
    "build_type" : "zip",
    "build_hash" : "f27399d",
    "build_date" : "2016-03-30T09:51:41.449Z",
    "build_snapshot" : false,
    "lucene_version" : "{lucene_version}",
    "minimum_wire_compatibility_version" : "1.2.3",
    "minimum_index_compatibility_version" : "1.2.3"
  },
  "tagline" : "You Know, for Search"
}
