Netdata

Netdata collects metrics every second and displays them in high res, low-latency dashboards. By design its allowed it to operate on all your physical & virtual servers, cloud instances, Kubernetes clusters, as well as edge and IoT devices, enabling the monitoring of your systems, containers, and applications.

Fully scalable from just a single to thousands of servers, even in intricate multi/mixed/hybrid cloud setups, and with sufficient storage capacity, it can retain your metrics for extended periods, spanning years

• Data Collection: Collects metrics from over 800+ integrations, including OS metrics, container metrics, VMs, hardware sensors, app metrics, OpenMetrics exporters, StatsD, and logs.
• Real-Time Performance: Provides metrics in real-time with minimal latency and high precision, ensuring that data is available on the dashboard immediately after collection.
• Anomaly Detection: Unsupervised anomaly detection by training multiple machine-learning models for each metric, detecting irregularities based on each metric's historical behavior.
• Impecable Visualization: Offers robust visualization for clear and accurate data comprehension, allowing effortless data filtering, manipulation, and exploration directly within the dashboard, eliminating the need for complex query languages.
• Alerting Out of the Box: Comes with a comprehensive set of pre-configured alerts by default, to identify common issues and potential challenges, ensuring that critical problems are promptly recognized. Supports diverse notification methods for timely alerts.
• systemd Journal Logs Explorer - BETA: Enables users to conveniently browse, filter, and scrutinize system and application logs. It achieves this by directly accessing systemd journal files on individual hosts and centralization servers for infrastructure-wide log consolidation.
• Low Maintenance: Requires minimal maintenance efforts due to complete automation, covering automated dashboard creation, pre-configured alerts, automated metric identification and discovery, seamless scalability, high availability, and compatibility with CI/CD processes.
• Open and Extensible: Modular platform that can be extended in all possible ways, facilitating various customization options and smooth integration with other monitoring solutions.
