Get aliases

GET /_cat/aliases

Get the cluster's index aliases, including filter and routing information. This API does not return data stream aliases.

IMPORTANT: CAT APIs are only intended for human consumption using the command line or the Kibana console. They are not intended for use by applications. For application consumption, use the aliases API.

Query parameters

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. It supports comma-separated values, such as open,hidden.

  • local boolean

    If true, the request computes the list of selected nodes from the local cluster state. If false the list of selected nodes are computed from the cluster state of the master node. In both cases the coordinating node will send requests for further information to each selected node.

  • The period to wait for a connection to the master node. If the master node is not available before the timeout expires, the request fails and returns an error. To indicated that the request should never timeout, you can set it to -1.

Get the cluster health status

GET /_cat/health

IMPORTANT: CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the cluster health API. This API is often used to check malfunctioning clusters. To help you track cluster health alongside log files and alerting systems, the API returns timestamps in two formats: HH:MM:SS, which is human-readable but includes no date information; Unix epoch time, which is machine-sortable and includes date information. The latter format is useful for cluster recoveries that take multiple days. You can use the cat health API to verify cluster health across multiple nodes. You also can use the API to track the recovery of a large cluster over a longer period of time.

Query parameters

  • time string

    The unit used to display time values.

    Values are nanos, micros, ms, s, m, h, or d.

  • ts boolean

    If true, returns HH:MM:SS and Unix epoch timestamps.

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

Get the pending cluster tasks

GET /_cluster/pending_tasks

Get information about cluster-level changes (such as create index, update mapping, allocate or fail shard) that have not yet taken effect.

NOTE: This API returns a list of any pending updates to the cluster state. These are distinct from the tasks reported by the task management API which include periodic tasks and tasks initiated by the user, such as node stats, search queries, or create index requests. However, if a user-initiated task such as a create index command causes a cluster state update, the activity of this task might be reported by both task api and pending cluster tasks API.

Query parameters

  • local boolean

    If true, the request retrieves information from the local node only. If false, information is retrieved from the master node.

  • 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.

      • insert_order number Required

        The number that represents when the task has been inserted into the task queue.

      • priority string Required

        The priority of the pending task. The valid priorities in descending priority order are: IMMEDIATE > URGENT > HIGH > NORMAL > LOW > LANGUID.

      • source string Required

        A general description of the cluster task that may include a reason and origin.

      • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

      • Time unit for milliseconds

Reroute the cluster Added in 5.0.0

POST /_cluster/reroute

Manually change the allocation of individual shards in the cluster. For example, a shard can be moved from one node to another explicitly, an allocation can be canceled, and an unassigned shard can be explicitly allocated to a specific node.

It is important to note that after processing any reroute commands Elasticsearch will perform rebalancing as normal (respecting the values of settings such as cluster.routing.rebalance.enable) in order to remain in a balanced state. For example, if the requested allocation includes moving a shard from node1 to node2 then this may cause a shard to be moved from node2 back to node1 to even things out.

The cluster can be set to disable allocations using the cluster.routing.allocation.enable setting. If allocations are disabled then the only allocations that will be performed are explicit ones given using the reroute command, and consequent allocations due to rebalancing.

The cluster will attempt to allocate a shard a maximum of index.allocation.max_retries times in a row (defaults to 5), before giving up and leaving the shard unallocated. This scenario can be caused by structural problems such as having an analyzer which refers to a stopwords file which doesn’t exist on all nodes.

Once the problem has been corrected, allocation can be manually retried by calling the reroute API with the ?retry_failed URI query parameter, which will attempt a single retry round for these shards.

Query parameters

  • dry_run boolean

    If true, then the request simulates the operation. It will calculate the result of applying the commands to the current cluster state and return the resulting cluster state after the commands (and rebalancing) have been applied; it will not actually perform the requested changes.

  • explain boolean

    If true, then the response contains an explanation of why the commands can or cannot run.

  • metric string | array[string]

    Limits the information returned to the specified metrics.

  • If true, then retries allocation of shards that are blocked due to too many subsequent allocation failures.

  • 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.

  • timeout string

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

Claim a connector sync job Technical preview

PUT /_connector/_sync_job/{connector_sync_job_id}/_claim

This action updates the job status to in_progress and sets the last_seen and started_at timestamps to the current time. Additionally, it can set the sync_cursor property for the sync job.

This API is not intended for direct connector management by users. It supports the implementation of services that utilize the connector protocol to communicate with Elasticsearch.

To sync data using self-managed connectors, you need to deploy the Elastic connector service on your own infrastructure. This service runs automatically on Elastic Cloud for Elastic managed connectors.

Path parameters

application/json

Body Required

  • The cursor object from the last incremental sync job. This should reference the sync_cursor field in the connector state for which the job runs.

  • worker_hostname string Required

    The host name of the current system that will run the job.

Create or update auto-follow patterns Added in 6.5.0

PUT /_ccr/auto_follow/{name}

Create a collection of cross-cluster replication auto-follow patterns for a remote cluster. Newly created indices on the remote cluster that match any of the patterns are automatically configured as follower indices. Indices on the remote cluster that were created before the auto-follow pattern was created will not be auto-followed even if they match the pattern.

This API can also be used to update auto-follow patterns. NOTE: Follower indices that were configured automatically before updating an auto-follow pattern will remain unchanged even if they do not match against the new patterns.

Pause an auto-follow pattern Added in 7.5.0

POST /_ccr/auto_follow/{name}/pause

Pause a cross-cluster replication auto-follow pattern. When the API returns, the auto-follow pattern is inactive. New indices that are created on the remote cluster and match the auto-follow patterns are ignored.

You can resume auto-following with the resume auto-follow pattern API. When it resumes, the auto-follow pattern is active again and automatically configures follower indices for newly created indices on the remote cluster that match its patterns. Remote indices that were created while the pattern was paused will also be followed, unless they have been deleted or closed in the interim.

External documentation

Path parameters

  • name string Required

    The name of the auto-follow pattern to pause.

Query parameters

  • The period to wait for a connection to the master node. If the master node is not available before the timeout expires, the request fails and returns an error. It can also be set to -1 to indicate that the request should never timeout.

Get term vector information

POST /{index}/_termvectors

Get information and statistics about terms in the fields of a particular document.

You can retrieve term vectors for documents stored in the index or for artificial documents passed in the body of the request. You can specify the fields you are interested in through the fields parameter or by adding the fields to the request body. For example:

GET /my-index-000001/_termvectors/1?fields=message

Fields can be specified using wildcards, similar to the multi match query.

Term vectors are real-time by default, not near real-time. This can be changed by setting realtime parameter to false.

You can request three types of values: term information, term statistics, and field statistics. By default, all term information and field statistics are returned for all fields but term statistics are excluded.

Term information

  • term frequency in the field (always returned)
  • term positions (positions: true)
  • start and end offsets (offsets: true)
  • term payloads (payloads: true), as base64 encoded bytes

If the requested information wasn't stored in the index, it will be computed on the fly if possible. Additionally, term vectors could be computed for documents not even existing in the index, but instead provided by the user.


Start and end offsets assume UTF-16 encoding is being used. If you want to use these offsets in order to get the original text that produced this token, you should make sure that the string you are taking a sub-string of is also encoded using UTF-16.

Behaviour

The term and field statistics are not accurate. Deleted documents are not taken into account. The information is only retrieved for the shard the requested document resides in. The term and field statistics are therefore only useful as relative measures whereas the absolute numbers have no meaning in this context. By default, when requesting term vectors of artificial documents, a shard to get the statistics from is randomly selected. Use routing only to hit a particular shard.

Path parameters

  • index string Required

    The name of the index that contains the document.

Query parameters

  • fields string | array[string]

    A comma-separated list or wildcard expressions of fields to include in the statistics. It is used as the default list unless a specific field list is provided in the completion_fields or fielddata_fields parameters.

  • If true, the response includes:

    • The document count (how many documents contain this field).
    • The sum of document frequencies (the sum of document frequencies for all terms in this field).
    • The sum of total term frequencies (the sum of total term frequencies of each term in this field).
  • offsets boolean

    If true, the response includes term offsets.

  • payloads boolean

    If true, the response includes term payloads.

  • positions boolean

    If true, the response includes term positions.

  • The node or shard the operation should be performed on. It is random by default.

  • realtime boolean

    If true, the request is real-time as opposed to near-real-time.

  • routing string

    A custom value that is used to route operations to a specific shard.

  • If true, the response includes:

    • The total term frequency (how often a term occurs in all documents).
    • The document frequency (the number of documents containing the current term).

    By default these values are not returned since term statistics can have a serious performance impact.

  • version number

    If true, returns the document version as part of a hit.

  • The version type.

    Values are internal, external, external_gte, or force.

    • The maximum word length above which words will be ignored. Defaults to unbounded.

    • Ignore terms which do not occur in at least this many docs.

    • Ignore words with less than this frequency in the source doc.

    • The minimum word length below which words will be ignored.

  • Override the default per-field analyzer. This is useful in order to generate term vectors in any fashion, especially when using artificial documents. When providing an analyzer for a field that already stores term vectors, the term vectors will be regenerated.

  • 200 application/json
    Hide response attributes Show response attributes object
    • coordinator_stats array[object] Required

      Objects containing information about each coordinating ingest node for configured enrich processors.

    • executing_policies array[object] Required

      Objects containing information about each enrich policy that is currently executing.

      • name string Required
      • task object Required Additional properties

        • action string Required
        • cancelled boolean
        • cancellable boolean Required
        • Human readable text that identifies the particular request that the task is performing. For example, it might identify the search request being performed by a search task. Other kinds of tasks have different descriptions, like _reindex which has the source and the destination, or _bulk which just has the number of requests and the destination indices. Many requests will have only an empty description because more detailed information about the request is not easily available or particularly helpful in identifying the request.

        • headers object Required

          • * string Additional properties
        • id number Required
        • node string Required
        • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

        • Time unit for nanoseconds

        • Time unit for milliseconds

        • status object

          The internal status of the task, which varies from task to task. The format also varies. While the goal is to keep the status for a particular task consistent from version to version, this is not always possible because sometimes the implementation changes. Fields might be removed from the status for a particular request so any parsing you do of the status might break in minor releases.

        • type string Required
    • cache_stats array[object]

      Objects containing information about the enrich cache stats on each ingest node.

Get the async EQL status Added in 7.9.0

GET /_eql/search/status/{id}

Get the current status for an async EQL search or a stored synchronous EQL search without returning results.

Path parameters

  • id string Required

    Identifier for the search.

Responses

  • 200 application/json
    Hide response attributes Show response attributes object
    • id string Required
    • is_partial boolean Required

      If true, the search request is still executing. If false, the search is completed.

    • is_running boolean Required

      If true, the response does not contain complete search results. This could be because either the search is still running (is_running status is false), or because it is already completed (is_running status is true) and results are partial due to failures or timeouts.

    • Time unit for milliseconds

    • Time unit for milliseconds

    • For a completed search shows the http status code of the completed search.

Run an async ES|QL query Added in 8.13.0

POST /_query/async

Asynchronously run an ES|QL (Elasticsearch query language) query, monitor its progress, and retrieve results when they become available.

The API accepts the same parameters and request body as the synchronous query API, along with additional async related properties.

External documentation

Query parameters

  • The character to use between values within a CSV row. It is valid only for the CSV format.

  • Indicates whether columns that are entirely null will be removed from the columns and values portion of the results. If true, the response will include an extra section under the name all_columns which has the name of all the columns.

  • format string

    A short version of the Accept header, for example json or yaml.

    Values are csv, json, tsv, txt, yaml, cbor, smile, or arrow.

  • The period for which the query and its results are stored in the cluster. The default period is five days. When this period expires, the query and its results are deleted, even if the query is still ongoing. If the keep_on_completion parameter is false, Elasticsearch only stores async queries that do not complete within the period set by the wait_for_completion_timeout parameter, regardless of this value.

  • Indicates whether the query and its results are stored in the cluster. If false, the query and its results are stored in the cluster only if the request does not complete during the period set by the wait_for_completion_timeout parameter.

  • The period to wait for the request to finish. By default, the request waits for 1 second for the query results. If the query completes during this period, results are returned Otherwise, a query ID is returned that can later be used to retrieve the results.
