==== 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" : "{build_flavor}",
"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"
}
