Fluent Bit is a fast, lightweight log processor and forwarder compatible with multiple operating systems, designed to efficiently collect and ship data from diverse sources to various destinations. Its configuration is user-friendly, involving a single file divided into sections—Service, Input, Filter, and Output—each serving distinct roles in defining global properties, data sources, data alteration, and data destinations respectively. Fluent Bit supports the use of environment variables and allows for complex configurations to be organized and simplified using the @INCLUDE keyword, while also enabling the parsing of both structured and unstructured logs through pluggable parsers. The tool is versatile, demonstrated by examples such as a simple setup for tailing log files and a more intricate integration with Kubernetes, showcasing its adaptability to different environments and use cases. By leveraging Fluent Bit, users can enhance their system's observability and streamline troubleshooting processes, particularly when used in conjunction with platforms like Coralogix.
