# Fluent Bit v2.2 Documentation
[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. It has been made with a strong focus on performance to allow the collection and processing of telemetry data from different sources without complexity.
## Features
* High Performance: High throughput with low resources consumption
* Data Parsing
* Convert your unstructured messages using our 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
* More than 100 built-in plugins are available
* Extensibility
* Write any input, filter or output plugin in C language
* WASM: [WASM Filter Plugins](development/wasm-filter-plugins.md) or [WASM Input Plugins](development/wasm-input-plugins.md)
* Bonus: 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/introduction.md): Perform data selection and transformation using simple SQL queries
* Create new streams of data using query results
* Aggregation Windows
* Data analysis and prediction: Timeseries forecasting
* Portable: runs on Linux, macOS, Windows and BSD systems
