Netdata

Netdata is an infrastructure monitoring and troubleshooting platform that collects per second metrics, logs and traces from servers, containers and applications. Its open source agent installs with little configuration, ships more than 800 integrations, and includes dashboards and alerts out of the box. The vendor states a footprint of about 5 percent CPU and 150MB of RAM. AI is part of the product in two ways: machine learning that detects anomalies automatically on each node, and AI troubleshooting that helps investigate incidents, with MCP support so outside agents can query monitoring data. Parent nodes stream and store metrics centrally with long retention and high availability, while Netdata Cloud is a managed SaaS layer with SSO, role based access and mobile apps for iOS and Android. Cloud can also be deployed on premises for air gapped or sovereignty requirements. It is built for DevOps, SRE and platform teams that want real time visibility without assembling a monitoring stack. Published pricing has a Community plan that is free forever for up to 5 nodes and non commercial use, a Homelab plan at $90 per year with unlimited nodes under fair usage, and a Business plan at $4.50 per node per month, which the page totals as $540 a year, with a free trial. Government and on premises options are handled through sales.
