Autoscaling Groups Health Checks Should Be Checked
More Info:
This rule checks if your Amazon EC2 Auto Scaling groups that are associated with a Classic Load Balancer use Elastic Load Balancing health checks. The rule is NON_COMPLIANT if the Amazon EC2 Auto Scaling groups are not using Elastic Load Balancing health checks.

Triage and Remediation
Remediation
To remediate the misconfiguration of Autoscaling Groups Health Checks not being checked in AWS EC2 using the AWS console, follow these step-by-step instructions:
-
Login to AWS Console: Go to the AWS Management Console (https://aws.amazon.com/console/) and login to your account.
-
Navigate to EC2 Dashboard: Click on the “Services” dropdown menu at the top left corner and select “EC2” under the Compute section.
-
Select Autoscaling Groups: In the EC2 Dashboard, under the “Auto Scaling” section in the left-hand menu, click on “Auto Scaling Groups”.
-
Select the Autoscaling Group: Click on the Autoscaling Group that you want to remediate the health check misconfiguration for.
-
Edit Autoscaling Group Settings: In the Autoscaling Group details page, click on the “Edit” button to modify the group settings.
-
Update Health Check Configuration: Scroll down to the “Health check type” section and ensure that the “Health check type” is set to “EC2” or “ELB” based on your requirements.
-
Configure Health Check Parameters: Configure the health check parameters such as “Grace period” and “Health check grace period” based on your application’s requirements.
-
Save Changes: After updating the health check configuration, click on the “Update” or “Save” button to apply the changes to the Autoscaling Group.
-
Verify Configuration: Once the changes are saved, verify the health check configuration by checking the status of the Autoscaling Group and monitoring the health of the instances.
By following these steps, you can successfully remediate the misconfiguration of Autoscaling Groups Health Checks not being checked in AWS EC2 using the AWS console.
To remediate the misconfiguration of Autoscaling Groups Health Checks not being checked for AWS EC2 using AWS CLI, follow these steps:
- List all the autoscaling groups in your AWS account to identify the group that needs to be updated:
aws autoscaling describe-auto-scaling-groups
-
Identify the Autoscaling Group that needs to have health checks enabled and note down the name of the Autoscaling Group.
-
Update the Autoscaling Group to enable health checks by running the following command, replacing
<autoscaling-group-name>with the actual name of the Autoscaling Group:
aws autoscaling update-auto-scaling-group --auto-scaling-group-name <autoscaling-group-name> --health-check-type EC2 --health-check-grace-period 300
In this command, we are setting the health check type to EC2 and the health check grace period to 300 seconds. You can adjust the health check type and grace period as needed.
- Verify that the health checks have been successfully enabled for the Autoscaling Group by describing the Autoscaling Group again:
aws autoscaling describe-auto-scaling-groups --auto-scaling-group-names <autoscaling-group-name>
By following these steps, you can remediate the misconfiguration of Autoscaling Groups Health Checks not being checked for AWS EC2 using AWS CLI.
To remediate the misconfiguration of Autoscaling Groups Health Checks not being checked in AWS EC2 using Python, you can follow these steps:
- Import Boto3 Library: Boto3 is the AWS SDK for Python, which allows Python developers to write software that makes use of services like Amazon S3 and Amazon EC2. You need to have Boto3 installed in your Python environment.
import boto3
- Initialize Boto3 EC2 Client: To interact with the EC2 service, you need to create a Boto3 EC2 client.
ec2_client = boto3.client('ec2')
- Get Autoscaling Groups: Use the
describe_auto_scaling_groupsmethod to get a list of all Autoscaling Groups in your AWS account.
response = ec2_client.describe_auto_scaling_groups()
auto_scaling_groups = response['AutoScalingGroups']
- Enable Health Checks: For each Autoscaling Group, check if the health check is enabled. If not, update the Autoscaling Group to enable health checks.
for asg in auto_scaling_groups:
if not asg['HealthCheckType']:
ec2_client.update_auto_scaling_group(
AutoScalingGroupName=asg['AutoScalingGroupName'],
HealthCheckType='EC2',
HealthCheckGracePeriod=300
)
- Complete Python Script:
import boto3
ec2_client = boto3.client('ec2')
response = ec2_client.describe_auto_scaling_groups()
auto_scaling_groups = response['AutoScalingGroups']
for asg in auto_scaling_groups:
if not asg['HealthCheckType']:
ec2_client.update_auto_scaling_group(
AutoScalingGroupName=asg['AutoScalingGroupName'],
HealthCheckType='EC2',
HealthCheckGracePeriod=300
)
- Run the Python Script: Save the script in a file (e.g.,
remediate_health_checks.py) and run it using Python. Make sure your AWS credentials are properly configured on your system.
python remediate_health_checks.py
By following these steps, you can remediate the misconfiguration of Autoscaling Groups Health Checks not being checked in AWS EC2 using Python.
