WHO WE ARE
Netdata is an open-source, real-time infrastructure monitoring platform. Monitor, detect, and act across your entire infrastructure.
**Core Advantages:**
* **Instant Insights** – With Netdata you can access per-second metrics and visualizations.
* **Zero Configuration** – You can deploy immediately without complex setup.
* **ML-Powered** – You can detect anomalies, predict issues, and automate analysis.
* **Efficient** – You can monitor with minimal resource usage and maximum scalability.
* **Secure & Distributed** – You can keep your data local with no central collection needed.
With Netdata, you get real-time, per-second updates. Clear **insights at a glance**, no complexity.
All heroes have a great origin story. Click to discover ours.
In 2013, at the company where Costa Tsaousis was COO, a significant percentage of their cloud-based transactions failed silently, severely impacting business performance.
Costa and his team tried every troubleshooting tool available at the time. None could identify the root cause. As Costa later wrote:
“*I couldn’t believe that monitoring systems provide so few metrics and with such low resolution, scale so badly, and cost so much to run.*”
Frustrated, he decided to build his own monitoring tool, starting from scratch.
That decision led to countless late nights and weekends. It also sparked a fundamental shift in how infrastructure monitoring and troubleshooting are approached, both in method and in cost.
Most Energy-Efficient Monitoring Tool
According to the University of Amsterdam study, Netdata is the most energy-efficient tool for monitoring Docker-based systems. The study also shows Netdata excels in CPU usage, RAM usage, and execution time compared to other monitoring solutions.
