Monitor AWS Network Load Balancer with Datadog

Amazon's Elastic Load Balancing (ELB) is an integral part of the AWS platform that distributes incoming traffic across EC2 instances. ELBs reduce maximum load on individual hosts, increase fault tolerance, and provide a single client-side connection point. There are three types of ELBs: Classic ELBs, Application Load Balancers (ALBs), and Network Load Balancers (NLBs). AWS NLBs differ from other ELBs in that they route incoming client requests at the TCP connection level using connection header details to determine which target to connect the client to. Monitoring NLBs is crucial for maintaining application functionality, as any issues may result in loss of application functionality. Datadog's AWS integration allows users to collect and analyze NLB metrics alongside other integrations, including Classic ELBs, ALBs, and the rest of the AWS platform. Key AWS NLB metrics include network traffic, reset packets, and host health. Monitoring these metrics can help identify potential issues in your application more efficiently.
