Grafana

Grafana is an open-source analytics and observability platform for visualizing, querying, and alerting on data from a wide range of sources. It connects to databases and systems such as Prometheus, Graphite, InfluxDB, Loki, Elasticsearch, MySQL, PostgreSQL, cloud monitoring services, and many others through a large ecosystem of plugins. Users can build interactive, real-time dashboards with panels for time-series graphs, tables, heatmaps, logs, and status indicators, enabling a unified view of metrics, logs, and traces.

The tool supports powerful query editors tailored to each data source, allowing users to explore data, apply transformations, and correlate signals across systems. Alerting capabilities let teams define threshold- or query-based alerts, route notifications to channels like email, Slack, PagerDuty, or webhooks, and manage alert rules centrally. Grafana’s role-based access control, folder structure, and team management features support secure, multi-tenant environments.
