== Nodes Task API

The nodes task management API retrieves information about the tasks currently
executing on one or more nodes in the cluster.

[source,js]
--------------------------------------------------
GET /_tasks <1>
GET /_tasks/nodeId1,nodeId2 <2>
GET /_tasks/nodeId1,nodeId2/cluster:* <3>
--------------------------------------------------
// AUTOSENSE

<1> Retrieves all tasks currently running on all nodes in the cluster.
<2> Retrieves all tasks running on nodes `nodeId1` and `nodeId2`.  See <<cluster-nodes>> for more info about how to select individual nodes.
<3> Retrieves all cluster-related tasks running on nodes `nodeId1` and `nodeId2`.

The result will look similar to the following:
