About Grafana
Grafana is the visualization layer of modern infrastructure: point it at Prometheus, Loki, Elasticsearch, or dozens of other sources and build dashboards operators live inside. The open-source core is free forever, while Grafana Cloud bundles managed metrics, logs, and traces with a workable free tier. Dashboard sprawl is the eternal hazard; governance features help.
