Amazon's Elastic Load Balancing (ELB) allows for the distribution of incoming traffic requests across EC2 instances, reducing maximum load on individual hosts and increasing fault tolerance. The three types of ELBs offered by Amazon are Classic ELBs, Application Load Balancers (ALBs), and Network Load Balancers (NLBs). NLBs route incoming client requests at the TCP connection level, using connection header details to determine which target to connect the client to. Datadog's AWS integration now allows users to collect and analyze NLB metrics alongside more than 850 other integrations, including Classic ELBs, ALBs, and the rest of the AWS platform. The integration comes with a customizable dashboard that enables users to start monitoring their NLB metrics right away, along with relevant tags provided by Amazon CloudWatch. Datadog's NLB integration allows users to monitor network traffic, reset packets, and host health, providing insights into key network traffic metrics to help troubleshoot possible issues in applications more efficiently. The integration also enables users to compare and correlate network traffic with metrics across other components of their infrastructure to determine which resources need to be scaled accordingly.
