Prometheus is a powerful open-source tool for real-time monitoring of applications, microservices, and networks, especially useful for monitoring Kubernetes clusters. It was originally developed by SoundCloud in 2012 and is now part of the Cloud Native Computing Foundation. Prometheus offers a dimensional data model, a powerful query language called PromQL, and reliability as its main advantages. Integrating Prometheus with New Relic One can help scale Prometheus and set up long-term storage and role-based access control. New Relic provides durable storage for thirteen months, RBAC, custom user groups, and levels of access, making it easier to import Prometheus metrics and reduce overhead for teams. Users can query Prometheus metrics in New Relic using PromQL-style queries, set up alerts on metrics, and visualize data with dashboards. The integration allows users to harness the power of fire by sharing Prometheus metrics with others, just like Prometheus from Greek mythology shared fire with humanity.
