Prometheus is an open-source toolkit that provides monitoring and alerting for services and applications running in containers, widely used to collect metrics data from Kubernetes environments. The New Relic Prometheus OpenMetrics integration allows users to send their Prometheus metrics directly to New Relic for storage, visualization, and correlation with other telemetry data, removing the overhead of managing Prometheus storage and availability. With this integration, users can monitor key aspects of their Kubernetes environments, such as etcd performance and health metrics, Kubernetes horizontal pod autoscaler (HPA) capacity, and node readiness. The integration supports both Docker and Kubernetes, using Prometheus version 2, and provides tools to visualize and alert on these metrics, making it easy for organizations to get started with Prometheus and scale their data without the hassles of managing Prometheus and a dashboard tool like Grafana.
