Fluent Bit

Fluent Bit is a high-performance log processor and stream processor for Linux, BSD-family, and Windows Operating systems.

Nowadays the number of sources of information in our environments is ever increasing. Handling data collection at scale is complex, and collecting and aggregating diverse data requires a specialized tool that can deal with:

• Different sources of information
• Different data formats
• Data Reliability
• Security
• Flexible Routing
• Multiple destinations

Fluent Bit provides a flexible and pluggable architecture to collect, enrich, and deliver logs or metrics to multiple databases or cloud providers.
