   curl -XGET "http://elasticsearch-marvel-01:9200/_template/marvel?pretty"
   

   This will return a large JSON object. The settings that are important are marvel.order, marvel.template, and marvel.settings:

   {
     "marvel" : {
       "order" : 0,
       "template" : ".marvel*",
       "settings" : {
         "index.mapper.dynamic" : "true",
         "index.marvel.index_format" : "6",
         "index.analysis.analyzer.default.type" : "standard",
         "index.number_of_replicas" : "1",
         "index.number_of_shards" : "1",
    "index.analysis.analyzer.default.stopwords" ...
