GET /{index}/_ilm/explain
Api key auth Basic auth Bearer auth

Get the current lifecycle status for one or more indices. For data streams, the API retrieves the current lifecycle status for the stream's backing indices.

The response indicates when the index entered each lifecycle state, provides the definition of the running phase, and information about any failures.

Required authorization

  • Index privileges: view_index_metadata,manage_ilm

Path parameters

  • index string Required

    Comma-separated list of data streams, indices, and aliases to target. Supports wildcards (*). To target all data streams and indices, use * or _all.

Query parameters

  • only_errors boolean

    Filters the returned indices to only indices that are managed by ILM and are in an error state, either due to an encountering an error while executing the policy, or attempting to use a policy that does not exist.

  • only_managed boolean

    Filters the returned indices to only indices that are managed by ILM.

  • master_timeout string

    Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
