FluentBit
Fluent Bit is a lightweight, open-source telemetry agent for collecting, processing, enriching, and forwarding logs and other event data.
Logs and Telemetry
Fluent Bit is a lightweight, high-performance telemetry agent for collecting, processing, and forwarding logs and other observability data.
- How it is used
- Routes logs, metrics, and traces from distributed sources into observability storage, aggregation, and analysis paths.
- How deep it goes
- Explains event structure, logical pipeline components, CLI controls, and extension options, while deferring detailed plugin implementation and advanced processing.
- Examples
- Demonstrates version checking, file logging, dummy-plugin help, configuration validation, and a pipeline architecture diagram.
- What you can do after
- Operate/configure it through CLI inputs, outputs, tags, configuration files, logging, and dry-run validation.
Cloud Observability in Action
Fluent Bit is a lightweight open-source agent for collecting, processing, and forwarding logs and other telemetry.
- How it is used
- Routes container and Kubernetes logs to centralized backends for storage, querying, visualization, and operational investigation.
- How deep it goes
- Explains resource positioning, pipeline roles, Docker Compose setup, and basic configuration while deferring detailed metrics and trace coverage.
- Examples
- Uses an EKS Fargate ConfigMap and a Docker Compose pipeline connecting ho11y, Fluentd, Fluent Bit, OpenSearch, and dashboards.
- What you can do after
- Operate/configure a basic Fluent Bit pipeline that receives container logs and forwards them to CloudWatch or OpenSearch.
gRPC Microservices in Go
Fluent Bit is a lightweight open-source agent for collecting, processing, and forwarding logs and other event data.
- How it is used
- Collects Kubernetes container logs and forwards them into a searchable observability stack for microservice operations.
- How deep it goes
- Explains node-level deployment and output configuration, but defers deep Elasticsearch-specific configuration.
- Examples
- Uses Kubernetes container files, Helm commands, an Elasticsearch output, Logstash formatting, TLS settings, and retry configuration.
- What you can do after
- Operate/configure a Kubernetes log collector that forwards pod logs to Elasticsearch with explicit authentication and retry behavior.
