Grafana is the reference platform for querying, visualizing, and understanding your data, wherever it is stored, and triggering alerts accordingly. Its guiding principle is to unify your existing data via data source plugins rather than forcing migration, thereby democratizing access to information within the organization.

The tool allows you to build flexible and polished dashboards from a rich palette of visualizations: time series, tables, gauges, histograms, heatmaps, graphs, and geo-maps. Built-in transformations allow renaming, aggregating, combining, and calculating across multiple queries, while annotations enrich graphs with events from multiple sources.

Grafana also centralizes alert management — creation, supervision, and silencing from a unified interface. Open source and widely deployed for observability, it integrates naturally with sources like Prometheus to offer complete supervision of your systems and services.
