Meet Fluent Bit v2.2!

Last week we announced the release of Fluent Bit v2.2 at KubeCon + CloudNativeCon North America. Eduardo Silva, original creator of Fluent Bit and Calyptia CEO, presented highlights from the new release at Observability Day, a KubeCon co-located event. You can watch the full video below.

Here are some highlights of the new release.

System information, including the hostname, the operating system, the kernel version, and the version of Fluent Bit running, is often invaluable when trying to diagnose an issue. Too often, though, system information is unavailable to downstream search and analytics platforms. The new Sysinfo plugin can automatically gather and enrich your logs with system information.

Fluent Bit already supported cgroups v2 for Podman. With this new release, Fluent Bit also adds support cgroups v2 for Docker containers. Now Fluent Bit offers parity for cgroups support across Podman and Docker with support for cgroups v1 and v2 on both platforms.

Fluent Bit now supports using either v1 or v2 of cgroups for pulling metrics from Docker containers

Classic Fluent Bit configuration files use a “YAML-inspired” format. Now you can use true YAML format. The classic format files will still work, and you can even use a mixture of the two formats for different config files for the same Fluent Bit instance. The change represents the project’s dedication to open standards.

The Node Exporter Metrics plugin is now able to collect extended metrics from Windows, giving you more insight into what is happening with your Windows-based machines. Support for macOS will be rolling out shortly.

We’ve completely reworked our integration with Grafana Loki to make it native. The original Loki Golang plugin is being deprecated.

The new Kubernetes Events plugin lets you collect cluster events through the API server. You can collect events from all namespaces, or limit it to specific namespaces.

Fluent Bit was already highly performant. That said, demands on data pipelines are growing and the Fluent Bit technology is advancing to keep up with these increased demands. We’ve improved Fluent Bit’s performance under the most demanding use cases. Testing of Fluent Bit v2.2 using multiple filters with hybrid mem+fs storage and checksums ON showed up to a 6X performance improvement based upon CPU and memory usage.

We’ve covered just the highlights of what Fluent Bit v2.2 offers. Check out the full changelog for all the nitty gritty details.

Fluent Bit has over 10 billion Docker pulls and is the industry standard open-source solution for processing and forwarding logs and metrics. It is deployed in major Kubernetes distributions, including Google Kubernetes Engine (GKE), AWS Elastic Kubernetes Service (EKS), Azure Kubernetes Service (AKS), and more.
