You should modify redis-stat/lib/redis-stat/elasticsearch.rb file.

`
24 def initialize hosts, elasticsearch
25 url, @index = elasticsearch
26 @hosts = hosts
27 @client = Elasticsearch::Client.new :url => url,
28 transport_options: {
29 headers: { 'Content-Type' => 'application/json' }
30 }
31 end

`
