 * *Parameters*:

-  ** `es_datastream_name`: This parameter is optional and can be used to set which data stream documents will be stored. When unspecified, logs will be stored in indexes of `logs-awsfirehose-default` data stream and metrics will be stored in indexes of `metrics-aws.cloudwatch-default` datas stream.
+  ** `es_datastream_name`: This parameter is optional and can be used to set which data stream documents will be stored. When unspecified, logs will be stored in `logs-awsfirehose-default` data stream and metrics will be stored in `metrics-aws.cloudwatch-default` data stream.
   ** `include_cw_extracted_fields`: This parameter is optional and can be set when using a CloudWatch logs subscription filter as the Firehose data source. When set to true, extracted fields generated by the filter pattern in the subscription filter will be collected. Setting this parameter can add many fields into each record and may significantly increase data volume in Elasticsearch. As such, use of this parameter should be carefully considered and used only when the extracted fields are required for specific filtering and/or aggregation.
   ** `set_es_document_id`: This parameter is optional and can be set to allow Elasticsearch to assign each document a random ID or use a calculated unique ID for each document. Default is true. When set to false, a random ID will be used for each document which will help indexing performance.
