Fluent Bit is a free, open-source telemetry agent for collecting and processing logs, metrics, and traces. It can run as an edge agent on constrained systems or as a central collector for cloud infrastructure, and is designed for high throughput with low resource consumption. Built-in parsers cover JSON, Regex, LTSV, and Logfmt; metrics compatibility includes Prometheus and OpenTelemetry. More than 100 built-in plugins cover inputs, filters, analytics, and outputs, with destinations including Splunk, Elasticsearch, OpenSearch, and Kafka. Buffering in memory or on the file system and backpressure handling support data flow, while network input and output plugins include TLS and SSL. Stream processing supports SQL queries, aggregation windows, forecasting, and data analysis. Users can write plugins in C, Lua, Golang, or WebAssembly. The Open-source Fluent Bit plan costs nothing, with self-hosted deployment under the Apache License 2.0. Official packages and installation guidance cover Linux, macOS, Windows, containers, and selected BSD and IBM Z Linux environments.
