An Amazon Auto Scaling Group contains a collection of Amazon Elastic Compute Cloud (EC2) instances that are treated as a logical grouping for automatic scaling and management.

To monitor this entity:

  1. Configure cloud connections in Cisco Cloud Observability. See Set up Cisco AppDynamics Cloud Collectors to Monitor AWS.
  2. In the AWS Management Console:
