Elastic Tasks API

The task management APIs enable you to get information about the tasks currently running on one or more nodes in the cluster.

Operations 4

POST /_tasks/_cancel Cancel a task #
POST /_tasks/{task_id}/_cancel Cancel a task #
GET /_tasks/{task_id} Get task information #
GET /_tasks Get all tasks #

Work with this as data

Every API here is available over the APIs.io API and to AI agents over MCP.

      description: 'WARNING: The task management API is new and should still be considered a beta feature.

        The API may change in ways that are not backwards compatible.


        A task may continue to run for some time after it has been cancelled because it may not be able to safely stop its current activity straight away.

        It is also possible that Elasticsearch must complete its work on other tasks before it can process the cancellation.

        The get task information API will continue to list these cancelled tasks until they complete.

        The cancelled flag in the response indicates that the cancellation command has been processed and the task will stop as soon as possible.


        To troubleshoot why a cancelled task does not complete promptly, use the get task information API with the `?detailed` parameter to identify the other tasks the system is running.

        You can also use the node hot threads API to obtain detailed information about the work the system is doing instead of completing the cancelled task.'

        WARNING: The task management API is new and should still be considered a beta feature.

        The API may change in ways that are not backwards compatible.


        **Identifying running tasks**


        The `X-Opaque-Id header`, when provided on the HTTP request header, is going to be returned as a header in the response as well as in the headers field for in the task information.

        This enables you to track certain calls or associate certain tasks with the client that started them.

        For example:


        ```

        curl -i -H "X-Opaque-Id: 123456" "http://localhost:9200/_tasks?group_by=parents"

        ```


        The API returns the following result:


        ```

        HTTP/1.1 200 OK

        X-Opaque-Id: 123456

        content-type: application/json; charset=UTF-8

        content-length: 831


        {

        "tasks" : {

        "u5lcZHqcQhu-rUoFaqDphA:45" : {

        "start_time_in_millis" : 1513823752749,

        "running_time_in_nanos" : 293139,

        "cancellable" : false,

        "headers" : {

        "X-Opaque-Id" : "123456"

        },

        "children" : [

        {

        "node" : "u5lcZHqcQhu-rUoFaqDphA",

        "id" : 46,

        "type" : "direct",

        ]

        }

        }

        }

        ```

        In this example, `X-Opaque-Id: 123456` is the ID as a part of the response header.

        The `X-Opaque-Id` in the task `headers` is the ID for the task that was initiated by the REST request.

        The `X-Opaque-Id` in the children `headers` is the child task of the task that was initiated by the REST request.'
