What are Netdata and Thanos?
Netdata
Netdata is a real-time monitoring agent that collects thousands of metrics per second and visualizes them with zero configuration. It targets administrators who want instant, granular system insight. It is deployed via Docker or native packages.
- Per-second real-time metrics
- Zero-configuration auto-discovery
- Built-in anomaly detection
- Thousands of collectors
Thanos
Thanos extends Prometheus with global query view, unlimited retention, and high availability. It uses object storage to keep metrics cheaply for years while presenting a single query endpoint across many Prometheus instances.
- Global query view
- Unlimited metric retention
- Object storage backend
- Downsampling for fast queries
