Building Observability on Amazon Managed Grafana for 5G O-RAN sites built on EKS-Anywhere

This article discusses building observability for 5G Open Radio Access Network (O-RAN) sites built on Amazon EKS Anywhere using Amazon Managed Grafana. It covers the following key points:

Specifically, the article covers:

• The architecture of an O-RAN site with three layers: server hardware, Kubernetes container runtime, and containerized O-RAN applications
• Monitoring the server layer using Redfish REST APIs or the Prometheus 'up' metric
• Monitoring the Kubernetes layer using metrics from utilities like kube-state-metrics, node-exporter, and container-advisor
• Monitoring O-RAN applications by either exposing Prometheus-compatible metrics for scraping or forwarding metrics using OpenTelemetry Protocol
• Visualizing and alerting on these metrics using Amazon Managed Grafana integrated with data sources like Amazon Managed Service for Prometheus
