Monitoring network performance on Amazon EKS using AWS Managed Open-Source Services

This article explains how to monitor network performance on Amazon EKS clusters using AWS managed open-source services and the new Container Network Observability features.

• Network Flow Monitor provides system and flow-level network performance metrics enriched with Kubernetes metadata
• Export Kubernetes-enriched network metrics to Amazon Managed Prometheus and visualize in Amazon Managed Grafana
• Service Map displays end-to-end visibility of network traffic flows across EKS workloads
• Network Flow Analysis provides granular application network activity and security posture insights
• Walkthrough includes creating EKS cluster, installing NFM agent addon, configuring Prometheus scraper
• Real-world testing with iperf demonstrated detection of bandwidth allowance violations and network throttling
• Supports integration with third-party observability platforms and self-managed Prometheus
• Grafana dashboards track throughput, packet drops, latency, connection states, and anomalies

This guide enables platform teams to gain Kubernetes-aware network telemetry for troubleshooting connectivity issues and optimizing EKS cluster performance.
