Grafana

Grafana is the observability platform that turns metric, log, and trace data into dashboards and charts, connecting to Prometheus, Loki, Tempo, PostgreSQL, and many other data sources through plugins. It offers a query editor, dashboard and folder organisation, annotations, alerting rules, and a wide panel library from latency histograms to log streams and trace waterfalls.

Teams use it as the single screen they watch during an incident.

Running it on your own infrastructure keeps dashboards and the links to your internal data sources inside your perimeter, avoids per-user or per-dashboard cloud pricing, and turns dashboard definitions into plain JSON files that are easy to version and restore.
