[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.![](https://static.scarf.sh/a.png?x-pxid=71f0e011-761f-4c6f-9a89-38817887faae)

## Features

- High performance: High throughput with low resources consumption
- Data parsing
  - Convert your unstructured messages using Fluent Bit parsers: [JSON](pipeline/parsers/json.md), [Regex](pipeline/parsers/regular-expression.md), [LTSV](pipeline/parsers/ltsv.md) and [Logfmt](pipeline/parsers/logfmt.md)
- Metrics support: Prometheus and OpenTelemetry compatible
- Reliability and data integrity
  - [Backpressure](administration/backpressure.md) handling
  - [Data buffering](administration/buffering-and-storage.md) in memory and file system
- Networking
  - Security: Built-in TLS/SSL support
  - Asynchronous I/O
- Pluggable architecture and [extensibility](development/library_api.md): Inputs, Filters and Outputs:
  - Connect nearly any source to nearly any destination using preexisting plugins
  - Extensibility:
    - Write input, filter, or output plugins in the C language
    - Wasm: [Wasm Filter Plugins](development/wasm-filter-plugins.md) or [Wasm Input Plugins](development/wasm-input-plugins.md)
    - Write [Filters in Lua](pipeline/filters/lua.md) or [Output plugins in Golang](development/golang-output-plugins.md)
- [Monitoring](administration/monitoring.md): Expose internal metrics over HTTP in JSON and [Prometheus](https://prometheus.io/) format
- [Stream Processing](stream-processing/overview.md): Perform data selection and transformation using basic SQL queries
  - Create new streams of data using query results
  - Aggregation windows
  - Data analysis and prediction: Time series forecasting
- Portable: Runs on Linux, macOS, Windows and BSD systems
