Fast and Lightweight Logs, Metrics and Traces processor

Fluent Bit is an open source telemetry agent that processes logs, metrics, traces, and profiles. It's designed to efficiently handle the challenges of collecting and processing telemetry data across a wide range of environments, from constrained systems to complex cloud infrastructures. Managing telemetry data from various sources and formats can be a constant challenge, particularly when performance is a critical factor. Rather than serving as a drop-in replacement, Fluent Bit enhances the observability strategy for your infrastructure. It adapts and optimizes your existing logging layer, and adds metrics and traces processing. Fluent Bit supports a vendor-neutral approach, with native OpenTelemetry (OTLP) ingestion and delivery and seamless integration with ecosystems such as Prometheus. Trusted by major cloud providers, banks, and companies that need a ready-to-use telemetry agent, Fluent Bit effectively manages diverse data sources and formats. It maintains optimal performance while keeping resource consumption low. Fluent Bit can be deployed as an edge agent for localized telemetry data handling or utilized as a central aggregator/collector for managing telemetry data across multiple sources and environments.
