Amazon ECS and EKS clusters running on Fargate can be monitored using Amazon CloudWatch, which aggregates monitoring data from many AWS services. CloudWatch collects metrics from ECS on Fargate in two separate namespaces: `AWS/ECS` for resource reservation and utilization metrics, and `ECS/ContainerInsights` for custom metrics that describe the status of ECS tasks and the number of running services, containers, and deployments. Container Insights is a separate namespace from `ECS/ContainerInsights` and stores EKS performance and resource metrics only from EC2-backed EKS clusters, not Fargate-backed EKS clusters. CloudWatch Logs collects logs from AWS services, including ECS on Fargate, and provides a console for exploring logs and a query language called CloudWatch Logs Insights for querying and analyzing logs. The Kubernetes Metrics API can be used to view metrics generated by cAdvisor, which runs as part of the kubelet on each compute resource. Prometheus can also collect cluster and resource metrics from Kubernetes, including EKS clusters running on Fargate, and stores metrics in a timeseries database. Fluent Bit can be used to route ECS logs to CloudWatch Logs, and kubectl can be used to view logs emitted by containerized applications. Datadog is a platform that collects, analyzes, and alerts on comprehensive monitoring data from Fargate and other technologies in the stack.
