Grafana
Grafana Labs
Grafana is open-source dashboard software that queries external data sources at render time. It unifies metrics, logs, and traces without storing data itself. Its JSON-based dashboards are versionable and composable. Since 2021, it uses AGPLv3 licensing. It originated from Graphite work at Orbitz and launched in January 2014. Its UI began as a fork of Kibana v3.
