The task management API allows to retrieve information about currently running tasks.
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
curl -XGET 'http://localhost:9200/_tasks'
|
|
curl -XGET 'http://localhost:9200/_tasks/nodeId1,nodeId2'
|
|
curl -XGET 'http://localhost:9200/_tasks/nodeId1,nodeId2/cluster:*'
|
|
--------------------------------------------------
|
|
|
|
The first command retrieves all tasks currently running on all nodes.
|
|
The second command selectively retrieves tasks from nodes
|
|
`nodeId1` and `nodeId2`. All the nodes selective options are explained
|
|
<<cluster-nodes,here>>.
|
|
The third command retrieves all cluster-related tasks running on nodes `nodeId1` and `nodeId2`.
|
|
|
|
The result will look similar to:
