It ingests and emits OTLP natively, processes telemetry efficiently at the edge or in-cluster, and routes data across hybrid environments without the operational weight of a larger collector deployment. Use Fluent Bit when you need a compact, high-performance telemetry data plane for logs, metrics, and traces. OpenTelemetry OpenTelemetry provides an open-source, vendor-neutral standard for Logs, Metrics, and Traces. It defines an open source schema for these telemetry data types, collectively known as signals, ensuring consistency and compatibility across diverse implementations. /announcements/v3.2.0/ Tue, 12 Nov 2024 00:00:00 +0000 /announcements/v3.2.0/ KNOWLEDGE BASE Release Notes v3.2.0 Fluent Bit is a Fast and Lightweight Telemetry Agent for Linux, BSD, macOS and Windows.

While multiline logs are hard to manage, many of them include essential information needed to debug an issue. In this blog, we will walk through multiline log collection challenges and how to use Fluent Bit to collect these critical logs.

As data increases within organizations, a single backend can put organizations at a disadvantage due to cost, use cases, and different stakeholders needing the same data (E.g., security and operations). Instead of installing multiple agents, users can leverage Fluentd and Fluent Bit to collect and route data to various backends. /announcements/v1.6.6/ Tue, 24 Nov 2020 00:00:00 +0000 /announcements/v1.6.6/ KNOWLEDGE BASE Release Notes v1.6.6 Fluent Bit is a Fast and Lightweight Data Forwarder for Linux, BSD and OSX.
