Fluent Bit
Fluent Bit is an open-source, lightweight, and high-performance log, metrics, and trace processor and forwarder. It's designed to collect data from various sources, filter, parse, and buffer it, then send it to multiple destinations, excelling in resource-constrained and cloud-native environments.

- Problem solved
- Fluent Bit was created to address the need for a significantly more lightweight and high-performance data collector for logs and metrics in resource-constrained environments, such as embedded systems, edge devices, and large-scale containerized deployments (like Kubernetes pods), where its spiritual predecessor, Fluentd, could be too resource-intensive.
