Fluentd: Unified Logging for Cloud-Native Systems

by Shriira Press

Fluentd is the open-source data collector for unified logging: it gathers logs and events from everywhere, parses and transforms them into a common structure, and routes them to wherever they need to go — decoupling sources from destinations. This free book teaches it from the ground up: the unified-logging model and structured-event pipeline, Fluentd's plugin architecture and tag-driven event flow, the configuration directives (source, filter, match, label), parsing and enriching data, buffering and reliability, the plugin ecosystem, Fluentd in Kubernetes (and how it compares to Fluent Bit), performance tuning and the forwarder/aggregator architecture, security, and operating it in production. Ten focused chapters with real config and clear diagrams that turn scattered, inconsistent log data into a unified, structured, reliably-delivered stream.
