About netdata

Netdata is an open-source, AI-powered monitoring and observability platform that provides per-second real-time visibility into your entire infrastructure. It features a self-learning AI agent that autonomously detects anomalies, performs root cause analysis, identifies blast radius, and offers an AI chat interface for troubleshooting. With extremely low resource usage (5% CPU, 150MB RAM, 3GB disk) and multi-year retention, Netdata can be deployed on-premises or via a fully managed cloud (Netdata Cloud). It supports 800+ integrations out of the box with zero configuration, offers customizable dashboards, native mobile apps, centralized metric streaming (Parent nodes), high availability clustering, and enterprise-grade security (SSO, RBAC, SOC2, ISO certified). The platform is linearly scalable with tiered retention, making it suitable for lean teams to large enterprises.
