Implementing Log Forwarding with Fluentd

Overview

This skill covers configuring Fluentd and Fluent Bit for centralized log collection, routing, and enrichment. Fluent Bit acts as a lightweight log forwarder on endpoints, while Fluentd serves as the central aggregator and processor. The configuration covers input plugins for syslog, file tailing, and application logs, with output routing to Elasticsearch, S3, and Splunk.

When to Use

• When deploying or configuring implementing log forwarding with fluentd capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

Prerequisites

• Fluentd (td-agent) v1.16+ or Fluent Bit v3.0+
• Python 3.8+ with fluent-logger library
• Elasticsearch or Splunk for log destination
