CloudWatch OTel Container Insights for Amazon EKS collects infrastructure metrics at 30-second granularity using open-source receivers including cAdvisor, Kube State Metrics, and NVIDIA DCGM. Each metric carries OpenTelemetry semantic conventions and Kubernetes labels, making it straightforward to correlate across nodes, pods, and workloads in a single PromQL query. Pre-built dashboards give you immediate visibility into cluster health, node performance, and pod-level resource usage.
