What is Fluent Bit?

Fluent Bit ships parallel version lines with eBPF tracing, GCS/OTLP expansion, and a steady stream of crash fixes.

Fluent Bit is running three active release branches simultaneously — 4.2.x, 5.0.x, and 5.1.x — with backports keeping the older lines current on security and correctness fixes. The 5.x line is where new capabilities land: eBPF-based tracing (DNS, scheduler, openssl), expanded GCS output (Workload Identity Federation, Parquet compression, Application Default Credentials), and OTLP metrics improvements. Crash fixes across in_tail, in_winevtlog, out_azure_blob, and the Kafka consumer show active hardening of production edge cases.

What is Fulcrum?

Fulcrum turns on Insights, its AI assistant for field data, for every customer.

Fulcrum, a field data collection platform, opened Insights to all customers on all plans as a public beta, on by default. Users ask questions in plain language across up to five apps and get charts, maps and tables, with an org-level off switch. Around it, web, iOS and Android releases fixed map, GPS and photo markup issues and tuned Photo FastFill and Insights styling.

Fluent Bit vs Fulcrum: editorial side-by-side

Fluent Bit
ANALYTICS
5.0

Fluent Bit ships parallel version lines with eBPF tracing, GCS/OTLP expansion, and a steady stream of crash fixes.

◆ Current state

Fluent Bit is running three active release branches simultaneously — 4.2.x, 5.0.x, and 5.1.x — with backports keeping the older lines current on security and correctness fixes. The 5.x line is where new capabilities land: eBPF-based tracing (DNS, scheduler, openssl), expanded GCS output (Workload Identity Federation, Parquet compression, Application Default Credentials), and OTLP metrics improvements. Crash fixes across in_tail, in_winevtlog, out_azure_blob, and the Kafka consumer show active hardening of production edge cases.

◆ Where it's heading

The eBPF input plugin is building out a full observability surface — DNS, scheduler, openssl traces added over several releases — suggesting a push toward kernel-level telemetry collection as a differentiator from Fluentd and other log shippers. The GCS output expansion (Parquet, WIF, ADC) follows the same pattern: depth-first feature addition to a specific destination rather than broad new connectors. The multiline JSON parser, namespace-scoped systemd capture, and Kubernetes namespace exclusion filter all point toward tighter Kubernetes-native operation.

◆ Prediction

The next move is likely more eBPF trace types (HTTP, TCP) completing the network observability set, and broader OTLP coverage given OpenTelemetry's growing dominance as the wire format in observability stacks.

6.3

Fulcrum turns on Insights, its AI assistant for field data, for every customer.

◆ Current state

Fulcrum, a field data collection platform, opened Insights to all customers on all plans as a public beta, on by default. Users ask questions in plain language across up to five apps and get charts, maps and tables, with an org-level off switch. Around it, web, iOS and Android releases fixed map, GPS and photo markup issues and tuned Photo FastFill and Insights styling.

◆ Where it's heading

Fulcrum is adding AI at both ends of its workflow: FastFill extracts data from photos and audio at capture, and Insights answers questions about the data afterwards. Mobile releases stay focused on reliability for GPS and map features still in beta.

◆ Prediction

Expect Insights to move toward general availability or paid packaging once the beta collects usage, and GPS Integration to leave beta after the current fix cycle.
