Frequently asked questions
Fluent Bit or Fluentd?
Fluent Bit, written in C, uses a few megabytes of memory: it is built for per-node agents. Fluentd, written in Ruby, is still useful as an aggregator with its many plugins, but new deployments favour Fluent Bit.
Does Fluent Bit support OpenTelemetry?
Yes: it receives and sends OTLP (opentelemetry input and output) for logs, metrics and traces.
