通過以下請求方法創建一個名為 “tiered-storage-policy” 的 ISM policy：

PUT _plugins/_ism/policies/tiered-storage-policy

{"policy": {"description": "Changes replica count and deletes.","schema_version": 1,"default_state": "current","states": [{"name": "current","actions": [],"transitions": [{"state_name": "old","conditions": {"min_index_age": "7d"}}]},{"name": "old","actions": [{"replica_count": {"number_of_replicas": 0}}],"transitions": [{"state_name": "delete","conditions": {"min_index_age": "21d"}}]},{"name": "delete","actions": [{"delete": {}}],"transitions": []}]}
}

創建策略后，請將它附加到一個或多個索引：

POST _plugins/_ism/add/my-index
{"policy_id": "my-policy-id"
}
