# Monitor a Deadline Cloud customer-managed fleet health check with CloudFormation
<a name="examples-cfn-cmf-health-check"></a>

The [cmf\_templates](https://github.com/aws-deadline/deadline-cloud-samples/tree/mainline/cloudformation/farm_templates/cmf_templates) directory in the samples repository includes a `deadline-fleet-health-check.yaml` CloudFormation template that sets up continuous health check monitoring for a single Deadline Cloud customer-managed fleet with auto scaling. The template creates a Lambda function, an EventBridge rule, and a CloudWatch alarm that you can configure with an SNS topic.

To deploy the template, you need:
+ A Deadline Cloud farm and customer-managed fleet. Copy the Farm ID, Fleet ID, and Fleet Name from the fleet details page in the Deadline Cloud management console.
+ An EC2 Auto Scaling group that scales the fleet. Copy the Auto Scaling group name from the EC2 Auto Scaling console.
+ An SNS topic and subscription for the health check alarm. Copy the SNS topic ARN.
