Amazon EKS and Kubernetes Container Insights metrics - Amazon CloudWatch

Amazon EKS and Kubernetes Container Insights metrics

The following table lists the metrics and dimensions that Container Insights collects for Amazon EKS and Kubernetes. These metrics are in the ContainerInsights namespace. For more information, see Metrics.

If you do not see any Container Insights metrics in your console, be sure that you have completed the setup of Container Insights. Metrics do not appear before Container Insights has been set up completely. For more information, see Setting up Container Insights.

With the original version of Container Insights, the metrics are charged as custom metrics. With Container Insights with enhanced observability for Amazon EKS, Container Insights metrics are charged per observation instead of being charged per metric stored or log ingested. For more information about CloudWatch pricing, see Amazon CloudWatch Pricing.
