Netdata

Overview

Netdata is an open-source (GPLv3) real-time server monitoring tool, headquartered in the United States. Its core strength is collecting system metrics (CPU, memory, disk, network, processes, etc.) at second-level resolution and displaying them in beautiful real-time dashboards. It supports hundreds of preconfigured alert rules with automatic notifications on anomalies. Netdata also monitors applications (Nginx, MySQL, Redis, PostgreSQL, etc.). Deployment is minimal with a one-command install, while the cloud version provides centralized management and long-term storage. This page belongs to the automation tool providers category.
