Create a index in ES using the REST service

Elastic Stack Elasticsearch
1

I am using the REST service to create a index named "iislogs"

URL - http://myserver:9200/iislogs

But this is not generating logs on daily basis. e.g. filebeat-2016.27.03, logstash-2016-02-02.

How can I achieve this ?

Append the date to the index name.

This is what LS or beats is doing.
