Hi All,

I am trying to index logs using logstash to a dynamic index with the format "index=\>sample-%{[YYYY.MM](http://YYYY.MM)}". How can I assign number of Replica shards at the time of Dynamic Index creation?

You can set it through an [index template](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/indices-templates.html).

Hi Christian,

Thanks for the quick reply..

So, I think I will have to add number\_of\_replicas field to the settings block. And I don't understand what mappings, properties and created at block do? Can you please explain it?
