Grafana Has a Free Dashboarding Platform: Visualize Metrics, Logs, and Traces From Any Data Source

Your app is running in production. Is it healthy? You check logs with grep . You query the database for metrics. You guess at performance trends. When something breaks at 3 AM, you're blind. What if you had real-time dashboards showing every metric that matters — request latency, error rates, CPU usage, business KPIs — from any data source? That's Grafana. What Grafana Connects To Prometheus — metrics (CPU, memory, request counts) Loki — logs (structured log aggregation) Tempo — traces (distributed tracing) PostgreSQL/MySQL — query databases directly Elasticsearch — search and analytics CloudWatch, Azure Monitor, GCP — cloud provider metrics InfluxDB, TimescaleDB — time-series databases JSON API — any REST endpoint 50+ official data sources. Mix and match on the same dashboard. Quick Start docker run -d -p 3000:3000 grafana/grafana-oss # Open http://localhost:3000 (admin/admin) Example: Node.js API Monitoring 1.
