summary
Fluent Bit is a C-based, lightweight log and now metrics agent that claims ~10x better performance than Fluentd (Ruby) in recent benchmarks and registers ~2M Docker pulls/day; it uses MessagePack vs JSON internally, a hybrid memory+filesystem buffering design with memory‑mapped files, and exposes metrics via a new cmetrics library plus a Prometheus exporter and remote_write support. Node Exporter collectors are reimplemented as input plugins, nginx collector merged, outputs include InfluxDB today and planned Splunk/DataDog/CloudWatch; design is vendor‑agnostic and production‑ready.
