**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser): 1.1

**Describe the issue** :

We have recently started using ISM to transition our indices to warm and cold storage.

I am trying to set up a query to show which storage tier and policy state are applied to indices. I cannot seem to find any documentation on how this can be achieved. Has anyone had any success with this before?

You can use [explain index api](https://opensearch.org/docs/latest/im-plugin/ism/api/#explain-index) to get the current state of index.
