9 | 9 | [Fluent Bit](http://fluentbit.io) is a fast and lightweight telemetry agent for logs, metrics, and traces for Linux, macOS, Windows, and BSD family operating systems. Fluent Bit has been made with a strong focus on performance to allow the collection and processing of telemetry data from different sources without complexity.
