+# Exporting cAdvisor Stats to ElasticSearch
+
+cAdvisor supports exporting stats to [ElasticSearch](https://www.elastic.co/). To use ES, you need to provide the additional flags to cAdvisor:
+
+Set the storage driver as ES:
+
+```
+ -storage_driver=elasticsearch
+```
+
+Specify ES host address:
+
+```
+ -storage_driver_es_host="http://elasticsearch:9200"
+```
+
+There are also optional flags:
+
+```
+ # ElasticSearch type name. By default it's "stats".
+ -storage_driver_es_type="stats"
+ # ElasticSearch can use a sniffing process to find all nodes of your cluster automatically. False by default.
+ -storage_driver_es_enable_sniffer=false
+```
+
