[IMPORTANT]
|
|
====
|
|
cat APIs are only intended for human consumption using the command line or {kib}
|
|
console. They are _not_ intended for use by applications. For application
|
|
consumption, use the <<tasks,task management API>>.
|
|
====
|
|
|
|
Returns information about tasks currently executing in the cluster,
|
|
similar to the <<tasks,task management>> API.
|

==== {api-prereq-title}
|

|
|
* If the {es} {security-features} are enabled, you must have the `monitor` or
|
|
`manage` <<privileges-list-cluster,cluster privilege>> to use this API.
|

|
|
[[cat-tasks-api-desc]]
|
|
==== {api-description-title}
|
|
|
|
The cat task management API returns information
|
|
about tasks currently executing
|
|
on one or more nodes in the cluster.
|
|
It is a more compact view
|
|
of the JSON <<tasks,task management>> API.
