terraform-aws-observability-accelerator/modules/eks-monitoring

Infrastructure monitoring

This module provides EKS cluster monitoring with the following resources:

• AWS Distro For OpenTelemetry Operator and Collector
• AWS Managed Grafana Dashboard and data source
• Alerts and recording rules with AWS Managed Service for Prometheus

This module is inspired from the open source kube-prometheus-stack
