NetData - Open Source Datadog Alternative

In today's dynamic digital landscape, where applications and services run across diverse environments ranging from traditional data centers to cloud-native architectures, monitoring and observability have become indispensable. The ability to gain deep insights into system performance, detect anomalies in real-time, and troubleshoot issues promptly is critical for maintaining the health, reliability, and performance of modern infrastructures.

Enter Netdata, the open-source observability platform that has been gaining significant traction among DevOps engineers, SREs (Site Reliability Engineers), and system administrators. In this comprehensive guide, we'll explore what Netdata is, why it's gaining popularity, its key features, recent developments, and how you can get started with it.

What is Netdata?

Netdata is a real-time monitoring and troubleshooting tool designed to provide unparalleled visibility into the performance and health of your entire infrastructure, including servers, containers, virtual machines, and applications. Unlike traditional monitoring solutions that typically operate on a one-minute or five-minute polling interval, Netdata collects metrics at per-second resolution, offering high granularity and low-latency insights.

Key Features of Netdata:

  • Wide Range of Integrations: Netdata can collect metrics from over 800 integrations, covering operating system metrics, container metrics, virtual machines, hardware sensors, application metrics, and more.

  • Real-Time, High-Resolution Monitoring: All metrics are collected per second and are available on the dashboard immediately after collection, enabling real-time visibility into system performance.

  • Unsupervised Anomaly Detection: Netdata employs multiple machine learning models to detect anomalies based on the past behavior of each metric individually, facilitating proactive issue identification.

  • Powerful Visualization: Netdata offers clear and precise visualization capabilities, allowing users to quickly understand datasets, filter, slice, and dice data directly on the dashboard without the need for complex query languages.

  • Out-of-the-Box Alerts: It comes with hundreds of predefined alerts to detect common issues and pitfalls, ensuring that critical events don't go unnoticed. Netdata supports various notification methods to alert users when attention is required.

  • Low Maintenance: Netdata is fully automated, featuring automated dashboards, out-of-the-box alerts, auto-detection, and auto-discovery of metrics, zero-touch machine learning, easy scalability, and high availability.

  • Open and Extensible: As a modular platform, Netdata can be extended in various ways and integrates seamlessly with other monitoring solutions, offering flexibility and customization options.

Recent Developments and Innovations

Network Connections Explorer:

One of the latest additions to Netdata is the Network Connections Explorer, available in the nightly builds. This tool provides a visual representation of all sockets each server has, including IPv4 and IPv6, TCP, and UDP connections. It classifies connections as inbound, outbound, listen, and local, offering insights into network traffic patterns.

Energy Efficiency Study:

A study conducted by the University of Amsterdam highlighted Netdata's exceptional energy efficiency compared to other monitoring tools for Docker-based systems. Netdata emerged as the most energy-efficient tool while also demonstrating superior performance in CPU and RAM usage, execution time, and network traffic impact.

Performance Analysis:

In a comparative performance analysis with Prometheus, Netdata showcased significant advantages in resource utilization. On the same workload, Netdata consumed 35% less CPU, 49% less RAM, 12% less bandwidth, and 98% less disk I/O while being 75% more disk space efficient for high-resolution metrics storage.

Systemd Journal Logs Explorer:

Netdata now features a systemd journal logs explorer, enabling users to view, filter, analyze, and query systemd journal logs directly from the dashboard. This capability enhances the platform's troubleshooting capabilities, facilitating comprehensive log analysis alongside performance metrics.

Getting Started with Netdata

Getting started with Netdata is straightforward. You can begin by visiting the Project's Home Page and exploring the documentation, community forums, and resources available. Netdata offers extensive support for various platforms, including physical servers, virtual machines, containers, and cloud environments.


Netdata stands out as a powerful and efficient observability platform, providing real-time insights, proactive anomaly detection, and comprehensive monitoring capabilities for modern infrastructures. With its extensive feature set, active community support, and continuous innovation, Netdata is poised to become the go-to solution for monitoring and troubleshooting in diverse environments.
