Grafana is an open source analytics and visualization platform that connects to a wide range of data sources — including Prometheus, Loki, Tempo, Elasticsearch, and many databases — to provide a unified observability view. Teams use it to build dashboards, set up alerting, and correlate metrics, logs, and traces in a single interface.
Grafana’s plugin system allows extending it with new data sources, panel types, and app plugins, making it adaptable to a broad range of monitoring and business intelligence use cases.
