NetData

Netdata is an open-source infrastructure monitoring platform. It provides real-time visibility into servers, containers, and applications by collecting and processing metrics at per-second resolution. The software is deployed as an agent on nodes, supporting Linux, FreeBSD, macOS, and Windows, and can be used across physical servers, cloud environments, and IoT devices.

The system operates with a zero-configuration approach, automatically detecting and discovering services running on the host immediately upon deployment. It is designed for high efficiency, focusing on low CPU and RAM usage while providing a web-based interface for data visualization. Users can monitor a broad spectrum of components, ranging from hardware sensors and network interfaces to complex Kubernetes clusters and cloud provider infrastructure from AWS, GCP, and Azure.

Key features

• Per-second data collection and processing for real-time insights
• Automatic detection and discovery of system components
• Unsupervised anomaly detection using machine learning models at the edge
• High-performance storage with tiered archiving for long-term retention
• Interactive dashboards that allow data analysis without a query language
• Horizontal scaling through a parent-child centralization architecture
• Support for monitoring Docker, containerd, LXC, and Kubernetes
• Integration with packaged applications including PostgreSQL, MySQL, and MongoDB

Netdata utilizes a three-part architecture consisting of the Netdata Agent, Netdata Cloud, and the Netdata UI. The agent handles the core engine tasks including collection, storage, and alerting on the local server, ensuring that processing happens at the premises rather than in a central location. Netdata Cloud provides enterprise features such as user management and role-based access control without requiring the centralization of metric storage. The platform supports a wide array of inputs, including OpenMetrics and StatsD, and allows for synthetic checks of APIs, TCP ports, and certificates.

This tool is a high-resolution observability solution for DevOps engineers and system administrators who require immediate infrastructure telemetry and detailed performance monitoring.
