AWS ELB
Overview
AWS Elastic Load Balancing (ELB) is a service used to dispatch incoming web traffic from your applications across your Amazon EC2 backend instances, which may be in different availability zones. AWS ELB helps ensure a smooth user experience and provides increased fault tolerance, handling traffic peaks and failed EC2 instances without interruption. AIOps collects metrics and metadata from all three flavors of Elastic Load Balancers that AWS offers: Application, Classic, and Network Load Balancers.
Metrics
