Hello there @Bibhudutta_Mohanty  
I'll try this too.  
What versions of elastic and kibana are you running?

Am I correct in thinking that you wish to keep using the same index and completely remove the data older than 30 days?

I usually (for metrics data) use a data stream instead of a regular index. If you are not using metrics data, then pls disregard. With a data stream and ILM policy you'd we essentially writing to an alias (so to speak) and then the policy will automatically create the backing indices for you. In fact, I normally dont need to know the backing indice names.

Hi Tre\_Seymour,

"version" : {  
"distribution" : "opensearch",  
"number" : "2.4.1",  
"build\_type" : "tar"

yes your assumption is right, wish to keep using the same index and completely remove the data older than 30 days. its a timeseries log data so i need a proper ilm policy which can delete only 30 days old log data without deleting the index.

i want your suggestion if i need one rollover policy?

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance.

ILM is an Elasticsearch only feature, you will need to ask aws directly what opensearch uses there.
