# CAT tasks
**Introduced 1.0**
{: .label .label-purple }

The CAT tasks operation lists the progress of all tasks currently running on your cluster.

## Example

```
GET _cat/tasks?v
```
{% include copy-curl.html %}

## Path and HTTP methods

```
GET _cat/tasks
```

## URL parameters

All CAT tasks URL parameters are optional.

In addition to the [common URL parameters]({{site.url}}{{site.baseurl}}/api-reference/cat/index), you can specify the following parameters:

Parameter | Type | Description
:--- | :--- | :---
nodes | List | A comma-separated list of node IDs or names to limit the returned information. Use `_local` to return information from the node you're connecting to, specify the node name to get information from specific nodes, or keep the parameter empty to get information from all nodes.
detailed | Boolean | Returns detailed task information. (Default: false)
parent_task_id | String | Returns tasks with a specified parent task ID (node_id:task_number). Keep empty or set to -1 to return all.
time | Time | Specify the units for time. For example, `5d` or `7h`. For more information, see [Supported units]({{site.url}}{{site.baseurl}}/opensearch/units/).
