Calyptia announced the release of Fluent Bit v2, the Cloud Native Computing Foundation (CNCF) open-source project for the collection, processing and delivery of logs, metrics and traces.

With Fluent Bit deployed over three billion times and in use by major cloud providers such as AWS, Google and Azure, Fluent Bit v2 adds major new observability integrations with full support for OpenTelemetry, Prometheus Metrics and added extensibility with WebAssembly plugins.

With the growth and standardization of OpenTelemetry for distributed tracing, Fluent Bit’s new integration for OpenTelemetry allows users to capture OpenTelemetry traces, metrics and logs as well as route data to any OpenTelemetry compatible endpoint. This routing also includes using the OpenTelemetry protocol. Additionally, with millions of users running Prometheus and OpenMetrics in production, Fluent Bit can also be used to retrieve and route that data in native Prometheus format. These additions and integrations build on Fluent Bit’s commitment to being the vendor-neutral solution for enterprise observability pipelines.

Fluent Bit is used to gather the massive amounts of telemetry data produced by modern cloud-native applications, process that data, and then deliver it to various other applications and systems for storage and analysis. Fluent Bit has always taken a vendor-neutral approach to the systems and applications with which it integrates, supporting competing industry telemetry standards and allowing users to interoperate freely in the rapidly evolving observability marketplace.

Earlier this month, Fluent Bit surpassed three billion downloads and deployments, making it one of the most valuable open-source projects in the observability space.

“Fluent Bit v2 is the most significant release ever for the project,” said Fluent Bit creator and Calyptia CEO Eduardo Silva. “Fluent Bit is the new standard agent on most cloud providers. As the project’s primary maintainers, Calyptia is dedicated to making Fluent Bit the fastest and lowest resource utilization solution to drive observability data pipelines, but Fluent Bit v2 would not have been possible without others like Microsoft and Observe, Inc. who also made significant contributions to this release. Fluent Bit is a great example of how open-source communities work together for a common solution.”

The new release also includes a feature called Tap that allows users to see in real time exactly how their observability data is transformed at any stage in its journey.

Fluent Bit v2 also improves the developer experience by allowing them to extend Fluent Bit by writing plugins in Go or WebAssembly (Wasm).

Other enhancements include additional security options that allow for data encryption throughout the data pipeline as well as performance improvements.
