 ### Description
 
+输出数据到 ElasticSearch
 
 ### Options
 
+| name | type | required | default value |
+| --- | --- | --- | --- |
+| [hosts](#hosts-array) | array | yes | - |
+| [index_type](#index_type-string) | string | no | log |
+| [index_time_format](#index_time_format-string) | string | no | yyyy.MM.dd |
+| [index](#index-string) | string | no | waterdrop |
+
+##### hosts [array]
+
+Elasticsearch集群地址，格式为host:port，允许指定多个host。如["host1:9200", "host2:9200"]。
+
+##### index_type [string]
+
+Elasticsearch index type
+
+##### index_time_format [string]
+
+当`index`参数中的格式为`xxxx-${now}`时，`index_time_format`可以指定index名称的时间格式，默认值为 `yyyy.MM.dd`。常用的时间格式列举如下：
+
+| Symbol | Description |
+| --- | --- |
+| y | Year |
+| M | Month |
+| d | Day of month |
+| H | Hour in day (0-23) |
+| m | Minute in hour |
+| s | Second in minute |
+
+详细的时间格式语法见[Java SimpleDateFormat](https://docs.oracle.com/javase/tutorial/i18n/format/simpleDateFormat.html)。
+
+
+##### index [string]
+
+Elasticsearch index名称，如果需要根据时间生成index，可以指定时间变量，如：`waterdrop-${now}`。`now`代表当前数据处理的时间。
+
 
 ### Examples
+
+```
+elasticsearch {
+    hosts = ["localhost:9200"]
+    index = "waterdrop"
+}
+```
+
+> 将结果写入Elasticsearch集群的名称为 waterdrop 的索引中
