[FIXED] How to check what storage phase is an index in (hot, worm...) - Elastic Search

Issue

I added a life cycle policy and want to ensure it takes effect and the indices are in the 'warm' phase as they should be.

I couldn't find what is the command to view that information. Is it possible? And if so, how?

Solution

You can use Explain Lifecycle API for checking current phase of Index.

GET my-index-000001/_ilm/explain

{
  "indices": {
    "my-index-000001": {
      "index": "my-index-000001",
      "index_creation_date_millis": 1538475653281,  
      "time_since_index_creation": "15s",           
      "managed": true,                              
      "policy": "my_policy",                        
      "lifecycle_date_millis": 1538475653281,       
      "age": "15s",                                 
      "phase": "new",  <--- this is indicating phase of index. 
      "phase_time_millis": 1538475653317,           
      "action": "complete"
      "action_time_millis": 1538475653317,          
      "step": "complete",
      "step_time_millis": 1538475653317             
    }
  }
}
