Exam AWS-SysOps topic 1 question 531 discussion

By installing the CloudWatch memory monitoring scripts on the instances in the Auto Scaling group, you can collect memory utilization data. This data can be used to create a custom metric in CloudWatch that reflects the memory utilization of the instances. Once the custom metric is created, you can configure scaling policies based on the memory utilization metric. This allows the Auto Scaling group to scale up or down based on the memory demands of the application.

The CloudWatch monitoring scripts are deprecated We recommend that you use the CloudWatch agent to collect metrics and logs. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-scripts-intro.html
