Fluent Bit Log Collection

Fluent Bit is a lightweight, high-performance log collector and shipper written in C. It reads logs from files, sockets, stdin, systemd journals, and container outputs, parses them (JSON, regex, multiline), filters noisy events, and forwards to centralized systems like Elasticsearch, Datadog, Splunk, or AWS CloudWatch. Fluent Bit is 100x smaller than Fluentd (1MB vs 100MB) and uses 10x less CPU. It's the standard for edge devices, IoT, Lambda functions, and containerized workloads. Every Kubernetes cluster running observability needs Fluent Bit (or similar) as the log collection layer.
