Experience with Fluentd/Fluent Bit:

I have hands-on experience designing, deploying, and managing log collection pipelines using both Fluentd and Fluent Bit in cloud-native environments.

• Log Aggregation: I’ve configured Fluent Bit as a lightweight forwarder on Kubernetes nodes to collect container logs and forward them to Fluentd aggregators for further processing.

• Parsing & Filtering: I’ve set up Fluentd to parse JSON, syslog, and multiline log formats, and applied filters to enrich, redact, or route logs based on metadata.

• Integrations: I have integrated Fluentd/Fluent Bit with various backends, including Elasticsearch, OpenSearch, Amazon S3, Loki, and cloud-native logging solutions.

• Performance Tuning: I optimized buffer and flush parameters in both tools to handle high log volumes with minimal resource overhead.

• Troubleshooting: I am comfortable debugging configuration issues, analyzing logs from the Fluentd/Fluent Bit daemons, and using tools like fluent-cat to verify data flows.

• Configuration Management: I managed configuration using ConfigMaps and Helm Charts for Kubernetes deployments, ensuring scalable and maintainable setups.

• Custom Plugins: I have some experience developing and extending custom Fluentd plugins (in Ruby) to meet specific business requirements.

Overall, I’m confident in architecting and maintaining robust log pipelines using Fluentd and Fluent Bit, and in supporting observability goals in modern infrastructure.
