Netdata

Netdata transforms infrastructure monitoring by providing real-time, per-second metrics collection and visualization without the complexity of traditional observability stacks. Built in C for maximum performance, it auto-detects thousands of applications and services the moment they start, requiring zero configuration to begin monitoring your entire infrastructure.

Unlike heavyweight monitoring solutions that demand extensive setup and maintenance, Netdata delivers immediate value with its distributed architecture. Each node runs an autonomous agent that collects, stores, and analyzes metrics locally, eliminating the need for centralized data lakes while providing sub-second granularity. The built-in machine learning engine automatically learns normal behavior patterns and alerts you to genuine anomalies, dramatically reducing alert fatigue.

The platform seamlessly integrates with existing tools like Prometheus, Grafana, and InfluxDB, while offering its own intuitive web interface for instant troubleshooting. With support for Docker, Kubernetes, databases, and over 800 integrations, Netdata scales from single servers to massive cloud-native deployments. Its efficient design means minimal resource overhead—typically under 1% CPU and a few MB of RAM per monitored system.

As a CNCF sandbox project with enterprise-grade features available in both open-source and commercial editions, Netdata empowers lean teams to achieve full-stack observability without the traditional cost and complexity barriers.
