• The AWS Systems Manager CloudWatch Dashboard will no longer be available after April 30, 2026. Customers can continue to use Amazon CloudWatch console to view, create, and manage their Amazon CloudWatch dashboards, just as they do today.

# Assign targets to a maintenance window using the console
<a name="sysman-maintenance-assign-targets"></a>

In this procedure, you register a target with a maintenance window. In other words, you specify which resources the maintenance window performs actions on.

**Note**  
If a single maintenance window task is registered with multiple targets, its task invocations occur sequentially and not in parallel. If your task must run on multiple targets at the same time, register a task for each target individually and assign each task the same priority level.

**To assign targets to a maintenance window using the console**

1. Open the AWS Systems Manager console at [https://console.aws.amazon.com/systems-manager/](https://console.aws.amazon.com/systems-manager/).

1. In the navigation pane, choose **Maintenance Windows**. 

1. In the list of maintenance windows, choose the maintenance window to add targets to.

1. Choose **Actions**, and then choose **Register targets**.

1. (Optional) For **Target name**, enter a name for the targets.

1. (Optional) For **Description**, enter a description.

1. (Optional) For **Owner information**, specify information to include in any Amazon EventBridge event raised while running tasks for these targets in this maintenance window.

   For information about using EventBridge to monitor Systems Manager events, see [Monitoring Systems Manager events with Amazon EventBridge](monitoring-eventbridge-events.md).

1. In the **Targets** area, choose one of the options described in the following table.    
[See the AWS documentation website for more details](http://docs.aws.amazon.com/systems-manager/latest/userguide/sysman-maintenance-assign-targets.html)

1. Choose **Register target**.

If you want to assign more targets to this maintenance window, choose the **Targets** tab, and then choose **Register target**. With this option, you can choose a different means of targeting. For example, if you previously targeted nodes by node ID, you can register new targets and target nodes by specifying tags applied to managed nodes or choosing resource types from a resource group.
