Grafana

Open and composable operational dashboards — query, visualize, alert on, and understand your metrics.

Grafana is the leading open-source platform for monitoring and observability, allowing you to query, visualize, alert on, and explore metrics, logs, and traces from any data source. It connects to dozens of backends including Prometheus, InfluxDB, Elasticsearch, PostgreSQL, CloudWatch, and more, unifying disparate monitoring data into cohesive dashboards. Grafana's dashboard builder supports hundreds of visualization types (time series, heatmaps, histograms, geomaps, gauges) with templating for dynamic, reusable dashboards. The alerting engine supports multi-dimensional alerts, notification routing to Slack, PagerDuty, email, and webhooks, with silences and alert grouping. Grafana Loki for log aggregation and Grafana Tempo for distributed tracing extend the platform into a full observability stack. With both open-source and cloud offerings, Grafana serves as the visualization layer for infrastructure and application monitoring worldwide.
