• 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. For more information, see [Amazon CloudWatch Dashboard documentation](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Dashboards.html). 

# Using roles to collect inventory and view OpsData
<a name="using-service-linked-roles-service-action-1"></a>

Systems Manager uses the service-linked role named **`AWSServiceRoleForAmazonSSM`**. AWS Systems Manager uses this IAM service role to manage AWS resources on your behalf.

## Service-linked role permissions for inventory, OpsData, and OpsItems
<a name="service-linked-role-permissions-service-action-1"></a>

The `AWSServiceRoleForAmazonSSM` service-linked role trusts only `ssm.amazonaws.com` to assume this role. 

You can use the Systems Manager service-linked role `AWSServiceRoleForAmazonSSM` for the following:
+ The Systems Manager Inventory tool uses the service-linked role `AWSServiceRoleForAmazonSSM` to collect inventory metadata from tags and resource groups.
+ The Explorer tool uses the service-linked role `AWSServiceRoleForAmazonSSM` to enable viewing OpsData and OpsItems from multiple accounts. This service-linked role also allows Explorer to create a managed rule when you enable Security Hub CSPM as a data source from Explorer or OpsCenter.

**Important**  
Previously, the Systems Manager console provided you with the ability to choose the AWS managed IAM service-linked role `AWSServiceRoleForAmazonSSM` to use as the maintenance role for your tasks. Using this role and its associated policy, `AmazonSSMServiceRolePolicy`, for maintenance window tasks is no longer recommended. If you're using this role for maintenance window tasks now, we encourage you to stop using it. Instead, create your own IAM role that enables communication between Systems Manager and other AWS services when your maintenance window tasks run.  
For more information, see [Setting up Maintenance Windows](setting-up-maintenance-windows.md).

The managed policy that is used to provide permissions for the `AWSServiceRoleForAmazonSSM` role is `AmazonSSMServiceRolePolicy`. For details about the permissions it grants, see [AWS managed policy: AmazonSSMServiceRolePolicy](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonSSMServiceRolePolicy).

## Creating the `AWSServiceRoleForAmazonSSM` service-linked role for Systems Manager
<a name="create-service-linked-role-service-action-1"></a>

You can use the IAM console to create a service-linked role with the **EC2** use case. Using commands for IAM in the AWS Command Line Interface (AWS CLI) or using the IAM API, create a service-linked role with the `ssm.amazonaws.com` service name. For more information, see [Creating a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#create-service-linked-role) in the *IAM User Guide*.

If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account. 

## Editing the `AWSServiceRoleForAmazonSSM` service-linked role for Systems Manager
<a name="edit-service-linked-role-service-action-1"></a>

Systems Manager doesn't allow you to edit the `AWSServiceRoleForAmazonSSM` service-linked role. After you create a service-linked role, you can't change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see [Editing a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#edit-service-linked-role) in the *IAM User Guide*.

## Deleting the `AWSServiceRoleForAmazonSSM` service-linked role for Systems Manager
<a name="delete-service-linked-role-service-action-1"></a>

If you no longer need to use any feature or service that requires a service-linked role, then we recommend that you delete that role. That way you don’t have an unused entity that isn't actively monitored or maintained. You can use the IAM console, the AWS CLI, or the IAM API to manually delete the service-linked role. To do this, you must first manually clean up the resources for your service-linked role, and then you can manually delete it.

Because the `AWSServiceRoleForAmazonSSM` service-linked role can be used by multiple tools, ensure that none are using the role before attempting to delete it.
+ **Inventory:** If you delete the service-linked role used by the Inventory tool, then the Inventory data for tags and resource groups will no longer be synchronized. You must clean up the resources for your service-linked role before you can manually delete it.
+ **Explorer:** If you delete the service-linked role used by the Explorer tool, then the cross-account and cross-Region OpsData and OpsItems are no longer viewable. 

**Note**  
If the Systems Manager service is using the role when you try to delete tags or resource groups, then the deletion might fail. If that happens, wait for a few minutes and try the operation again.

**To delete Systems Manager resources used by the `AWSServiceRoleForAmazonSSM`**

1. To delete tags, see [Add and delete tags on an individual resource](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html#adding-or-deleting-tags).

1. To delete resource groups, see [Delete groups from AWS Resource Groups](https://docs.aws.amazon.com/ARG/latest/userguide/deleting-resource-groups.html).

**To manually delete the `AWSServiceRoleForAmazonSSM` service-linked role using IAM**

Use the IAM console, the AWS CLI, or the IAM API to delete the `AWSServiceRoleForAmazonSSM` service-linked role. For more information, see [Deleting a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#delete-service-linked-role) in the *IAM User Guide*.
