Netdata is an open-source platform for real-time infrastructure monitoring. The Netdata Agent collects metrics every second, automatically discovers what runs on a system, flags anomalies using machine learning, and offers alerting and export to tools such as Prometheus and InfluxDB. It runs on Linux, FreeBSD, macOS and Windows, including containers and Kubernetes. Optionally there is Netdata Cloud, a commercial layer providing remote access, SSO, role-based access control and dashboards across multiple systems.
The Agent is open source under GPLv3 or later and runs on your own servers, where the metrics are also stored; according to the project, Netdata Cloud does not centralise metric storage. The default web interface and Netdata Cloud itself are closed source. For those wanting full control, Netdata Cloud On-Premises is also available, including for air-gapped environments. For a European organisation, self-hosting the Agent, optionally with its own Parent node to aggregate data, is the route that keeps monitoring data on its own infrastructure.
